Comparing Social Media Outlets for Developer Tips

As a little experiment, I shared a development tip on three different social networks. I also tried to post it in a format that was most suitable for that particular social network:

How did each of them “do”? Let’s take a look. But bear in mind… this ain’t scientific. This is just me having a glance at one isolated example to get a feel for things across different social media sites.

The Twitter Thread

The Tweet

Twitter is probably our largest social media outlet. Despite the fact that I’ve done absolutely nothing with it this year other than auto-tweeting posts from this site (via our Jetpack Integration), those tweets do just about as well as it ever did when I was writing each tweet. These numbers are bound to change, but at the time of writing:

Tweet Analytics showing 102,501 Impressions, 3,753 engagements and a few other more fine-grained stats.
Twitter provides analytics on tweets

Going off that engagements number, a little bit less than 1% of the followers had anything to do with it. I’d say this was a very average tweet for us, if not on the low side.

The Instagram Post

The Post

Instagram is by far the smallest of our social media outlets, being newer and not something I stay particularly active or consistent on. No auto-posting there just yet.

Instagram provides analytics (“insights”) on posts.

Using Reach, that’s 96% of the followers. That’s pretty incredible compared t 1% of followers on Twitter. Although, on Twitter. I can easily put URLs to tweets and send people places, where my only options on Instagram are “check out the link in my profile” or use a swipe-up thing in an Instagram Story. So, despite the high engagement of Instagram, I’m mostly just getting the satisfaction of teaching something as well as a little brand awareness. It’s much harder for me to get you to directly do something from Instagram.

The YouTube Video

The Video

YouTube is in the middle for us, much bigger than Instagram but not as big as Twitter. YouTube is a little unique in that there can be (and are) advertising directly on the videos and that get’s a “revenue share” from YouTube. That’s very much not driving motivation for using YouTube (I make 50 cents a day, but it is unique compared to the others.

We do have a Facebook page but it’s the most neglected of all of them. We auto-post new articles to it, but this experiment didn’t really have a blog post. I published the video to our site, but that doesn’t get auto-posted to Facebook, so the tip never made it there.

I used to feel a little guilty about not taking as much advantage of Facebook as I could, but whenever I look at overall analytics, I’m reminded that all of social media accounts combine for ~2% of traffic to this site. Spending any more time on this stuff is foolish for me, when that time could be spent on content for this site and information architecture for what we already have. And for Facebook specifically, whatever time we have spent there has never seemed to pan out. Just not a hive for developers.


I probably should have factored CodePen into this more, since it’s something of a social network itself with similar metrics. I worked on the examples in CodePen and the whole video was done in CodePen. But in this case, it was more about the journey than the destination. I did ultimately link to a demo at the end of the Twitter thread, but Instagram can’t link to it and I wasn’t as compelled to link to it on YouTube as the video itself to me was the important information.

If I was trying to compare CodePen stats here, I would have created the Pen in a step-by-step educational format so I could deliver the same idea. That actually sounds fun and I should probably still do that!



The problem is that there isn’t anything particularly useful to measure. What would have been way more interesting is if I had some really important call to action in each one where I’m like trying to sell you something or get you to sign up for something or whatever. I feel like that’s the real world of developer marketing. You gotta do 100 things for someone for free if you want them to do something for you on that 101st time. And on the 101st time, you should probably measure it somehow to see if the effort is worth it.

Here’s the very basic data together though…

Followers Engagements %
Twitter ~446,000 3,753 0.08%
Instagram ~2,800 2,685 96%
YouTube ~51,300 2,455 5%

One interesting thing is that I find the effort was about equal for all of them. You’d think a video would be hardest, but at least that’s just hit-record-hit-stop and minor editing. The other formats take longer to craft with custom text and graphics.

These would be my takeaways from this limited experiment:

  • You need big numbers on Twitter to do much. That’s because the engagement is pretty low. Still, it’s probably our best outlet for getting people to click a link and do something.
  • Instagram has amazing engagement, but it’s hard to send anyone anywhere. It’s still no wonder why people use it. You really do reach your audience there. If you had a strong call to action, I bet you could still get people do to it even with the absence of links (since people know how to search for stuff on the web).
  • While I mentioned that for this example the effort level was fairly even, in general, YouTube is going to require much higher effort. Video production just isn’t the same as farting out a couple of words or a screenshot. With that, and knowing that you’d need absolutely massive numbers to earn anything directly from YouTube, it’s pretty similar to other social networks in that you need to derive value from it abstractly.
  • This was not an idea that “went viral” in any sense. This is just standard-grade engagement, which was good for this experiment. I’m always super surprised at the type of developer tips that go viral. It’s always something I don’t expect, and often something I’m like awwwww we have an article about that too! I’d never bet on or expect anything going viral. Making stuff that your normal audience likes is the ticket.
  • Being active is pretty important. Any chart I’ve seen has big peaks when posts go out regularly and valleys when they don’t. Post regularly = riding the peaks.
  • None of this compares anywhere close to the real jewel of making things: blogging. Blogging is where you have full control and full benefit. The most important thing social media can do is get people over to your own site.

CSS fix for 100vh in mobile WebKit

CSS fix for 100vh in mobile WebKit

Not long ago there was some buzz around how WebKit handles 100vh in CSS, essentially ignoring the bottom edge of the browser viewport. Some have suggested avoid using 100vh, others have come up with different alternatives to work around the problem. In fact, this issue goes further back a few years when Nicolas Hoizey filed a bug with WebKit on the subject (the short of it: WebKit says this is “intentional” ?).

The other day I was doing some work with a basic flexbox layout – header, main, sticky footer – the kind we’ve all seen and used many times before:

<header>HEADER GOES HERE</header>
<main>MAIN GOES HERE</main>
<footer>FOOTER GOES HERE</footer>
body {
  display: flex; 
  flex-direction: column;
  margin: 0;
  min-height: 100vh;

main {
  flex: 1;

I began running some browser tests on my iPhone, and that’s when I noticed that my sticky footer wasn’t looking so sticky:

Mobile screen showing sticky footer below Safari's menu bar

The footer was hiding below Safari’s menu bar. This is the 100vh bug (feature?) that Nicolas originally uncovered and reported. I did a little sleuthing – hoping that maybe by now a non-hacky fix had been found – and that’s when I stumbled upon my own solution (btw, it’s totally hacky):

Using -webkit-fill-available

The idea behind -webkit-fill-available – at least at one point – was to allow for an element to intrinsically fit into a particular layout, i.e., fill the available space for that property. At the moment intrinsic values like this aren’t fully supported by the CSSWG.

However, the above problem is specifically in WebKit, which does support -webkit-fill-available. So with that in mind, I added it to my ruleset with 100vh as the fallback for all other browsers.

body {
  min-height: 100vh;
  /* mobile viewport bug fix */
  min-height: -webkit-fill-available;

And now the sticky footer is right where I want it to be in mobile Safari!

Does this really work?

The jury seems to be out on this. I’ve had no problems with any of the tests I’ve run and I’m using this method in production right now. But I did receive a number of responses to my tweet pointing to other possible problems with using this (the effects of rotating devices, Chrome not completely ignoring the property, etc.).

Will -webkit-fill-available work in every scenario? Probably not, cuz let’s be honest: this is the web, and it can be damn hard to build. But, if you’re having a problem with 100vh in WebKit and you’re looking for a CSS alternative, you might want to try this.

Basic Frontend Dev Environment Setup

In this post, I will share with you a very basic development environment setup which is very useful if you just quickly want to evaluate some functionality. At the same time, can act as a good foundation and can be extended once you are done with the initial testing.

Angular and React are nowadays the default choice for frontend development, but for simple POC and validation purposes, we don’t have to use those; this way, we can avoid complexity.

The idea is to keep it very simple and reuse this approach for other POC projects as well. However, if you want to see more details about specific topics e.g. Git, then you can find some posts written by me on those topics here on DZone or ask in comments. Ok, let’s see the steps involved in this setup.


  • Create a git-repo for the project. Add ReadMe and .gitignore files.
  • Initialize npm >> npm init
  • Install lite-server>>npm install –save-dev lite-server
  • Add lite-server config file: bs-config.json and update npm-start script: lite-server.
  • Install some initial dependencies:
    • npm install  — save bootstrap
    • npm install — save jquery
    • npm install — save font-awesome
  • Create index.html (see example code)

The result of following these steps is that you will have a starting point to test your idea. Furthermore, you can clone the sample-code repository, and you have all above mentioned steps already done for you. So, one git-clone command and the whole environment is available. At this point, the environment is done, and the whole idea was to keep it very minimum for quick reuse.

Screenshot of Index.html

The HTML code is available in the repo, and here are the screenshots of that simple HTML structure. 

Head of HTML file

Body of HTML file

Other Screenshots

Here are some other screenshots, showing the folder structure and some code. Again, if you clone the repo, you have all this available to you. 

Screenshots of file structure


So, this setup can now be reused for POC type cases. Let me know if you have any comments in this regard. Until next time, Happy Coding.

Registrar is selling my domain without asking? : web_design

So, my domain was going to expire and decided to renew it. For my surprise, when checking other registrars, I found that it was available for purchase for 9K+ $, as a “premium domain”. On some sites it would even show that “that’s the price the owner of the domain is asking”. WTF?
I checked on my registrar’s KB and it is said that, if a domain is on it’s 30th day of grace period after expire, they will put it on sale at Dynadot. But my domain was not expired… I renewed it on the same registrar because of being short of time, but I can see it’s still displayed as on sale! Is this even legal?
I never put it on sale.

For example, at GoDaddy:

Illustrating the ascender, cap height, x-height, baseline and descender of the Lato font with The quick fox as sample text.

How to Tame Line Height in CSS

In CSS, line-height is probably one of the most misunderstood, yet commonly-used attributes. As designers and developers, when we think about line-height, we might think about the concept of leading from print design — a term, interestingly enough, that comes from literally putting pieces of lead between lines of type. 

Leading and line-height, however similar, have some important differences. To understand those differences, we first have to understand a bit more about typography. 

An overview of typography terms

In traditional Western type design, a line of text is comprised of several parts: 

  • Baseline: This is the imaginary line on which the type sits. When you write in a ruled notebook, the baseline is the line on which you write.
  • Descender: This line sits just below the baseline. It is the line that some characters — like lowercase g, j, q, y and p  — touch below the baseline. 
  • X-height: This is (unsurprisingly) the height of a normal, lowercase x in a line of text. Generally, this is the height of other lowercase letters, although some may have parts of their characters that will exceed the x-height. For all intents and purposes, it servers as the perceived height of lowercase letters.
  • Cap-height: This is the height of most capital letters on a given line of text.
  • Ascender: A line that oftentimes appears just above the cap height where some characters like a lowercase h or b might exceed the normal cap height.
Illustrating the ascender, cap height, x-height, baseline and descender of the Lato font with The quick fox as sample text.

Each of the parts of text described above are intrinsic to the font itself. A font is designed with each of these parts in mind; however, there are some parts of typography that are left up to the type setter (like you and me!) rather than the designer. One of these is leading.

Leading is defined as the distance between two baselines in a set of type.

Two lines of text with an order box around the second line ofd text indicating the leading.

A CSS developer might think, “OK, leading is the line-height, let’s move on.” While the two are related, they are also different in some very important ways.

Let’s take a blank document and add a classic “CSS reset” to it:

* {
  margin: 0;
  padding: 0;

This removes the margin and padding from every single element.

We’ll also use Lato from Google Fonts as our font-family.

We will need some content, so let’s an create an <h1> tag with some text and set the line-height to something obnoxiously huge, like 300px. The result is a single line of text with a surprising amount of space both above and below the single line of text.

When a browser encounters the line-height property, what it actually does is take the line of text and place it in the middle of a “line box” which has a height matching the element’s line-height. Instead of setting the leading on a font, we get something akin to padding one either side of the line box.

Two lines of text with orange borders around each line of text, indicating the line box for each line. The bottom border of the first line and the top border of the second line are touching.

As illustrated above, the line box wraps around a line of text where leading is created by using space below one line of text and above the next. This means that for every text element on a page there will be half of the leading above the first line of text and after the last line of text in a particular text block.

What might be more surprising is that explicitly setting the line-height and font-size on an element with the same value will leave extra room above and below the text. We can see this by adding a background color to our elements.

This is because even though the font-size is set to 32px, the actual text size is something less than that value because of the generated spacing.

Getting CSS to treat line-height like leading

If we want CSS to use a more traditional type setting style instead of the line box, we’ll want a single line of text to have no space either above or below it — but allow for multi-line elements to maintain their entire line-height value. 

It is possible to teach CSS about leading with a little bit of effort. Michael Taranto released a tool called Basekick that solves this very issue. It does so by applying a negative top margin to the ::before pseudo-elementand a translateY to the element itself. The end result is a line of text without any extra space around it.

The most up-to-date version of Basekick’s formula can be found in the source code for the Braid Design System from SEEK. In the example below, we are writing a Sass mixin to do the heavy lifting for us, but the same formula can be used with JavaScript, Less, PostCSS mixins, or anything else that provides these kinds of math features.

@function calculateTypeOffset($lh, $fontSize, $descenderHeightScale) {
  $lineHeightScale: $lh / $fontSize;
  @return ($lineHeightScale - 1) / 2 + $descenderHeightScale;

@mixin basekick($typeSizeModifier, $baseFontSize, $descenderHeightScale, $typeRowSpan, $gridRowHeight, $capHeight) {
  $fontSize: $typeSizeModifier * $baseFontSize;
  $lineHeight: $typeRowSpan * $gridRowHeight;
  $typeOffset: calculateTypeOffset($lineHeight, $fontSize, $descenderHeightScale);
  $topSpace: $lineHeight - $capHeight * $fontSize;
  $heightCorrection: 0;
  @if $topSpace > $gridRowHeight {
    $heightCorrection: $topSpace - ($topSpace % $gridRowHeight);
  $preventCollapse: 1;
  font-size: #{$fontSize}px;
  line-height: #{$lineHeight}px;
  transform: translateY(#{$typeOffset}em);
  padding-top: $preventCollapse;

  &::before {
    content: "";
    margin-top: #{-($heightCorrection + $preventCollapse)}px;
    display: block;
    height: 0;

At first glance, this code definitely looks like a lot of magic numbers cobbled together. But it can be broken down considerably by thinking of it in the context of a particular system. Let’s take a look at what we need to know:

  • $baseFontSize:This is the normal font-size for our system around which everything else will be managed. We’ll use 16px as the default value.
  • $typeSizeModifier: This is a multiplier that is used in conjunction with the base font size to determine the font-size rule. For example, a value of 2 coupled with our base font size of 16px will give us font-size: 32px.
  • $descenderHeightScale: This is the height of the font’s descender expressed as a ratio. For Lato, this seems to be around 0.11.
  • $capHeight: This is the font’s specific cap height expressed as a ratio. For Lato, this is around 0.75.
  • $gridRowHeight: Layouts generally rely on default a vertical rhythm to make a nice and consistently spaced reading experience. For example, all elements on a page might be spaced apart in multiples of four or five pixels. We’ll be using 4 as the value because it divides easily into our $baseFontSize of 16px.
  • $typeRowSpan: Like $typeSizeModifier, this variable serves as a multiplier to be used with the grid row height to determine the rule’s line-height value. If our default grid row height is 4 and our type row span is 8, that would leave us with line-height: 32px.

Now we can then plug those numbers into the Basekick formula above (with the help of SCSS functions and mixins) and that will give us the result below.

That’s just what we’re looking for. For any set of text block elements without margins, the two elements should bump against each other. This way, any margins set between the two elements will be pixel perfect because they won’t be fighting with the line box spacing.

Refining our code

Instead of dumping all of our code into a single SCSS mixin, let’s organize it a bit better. If we’re thinking in terms of systems, will notice that there are three types of variables we are working with:

Variable Type Description Mixin Variables
System Level These values are properties of the design system we’re working with. $baseFontSize
Font Level These values are intrinsic to the font we’re using. There might be some guessing and tweaking involved to get the perfect numbers. $descenderHeightScale
Rule Level These values will are specific to the CSS rule we’re creating $typeSizeMultiplier

Thinking in these terms will help us scale our system much easier. Let’s take each group in turn.

First off, the system level variables can be set globally as those are unlikely to change during the course of our project. That reduces the number of variables in our main mixin to four:

$baseFontSize: 16;
$gridRowHeight: 4;

@mixin basekick($typeSizeModifier, $typeRowSpan, $descenderHeightScale, $capHeight) {
  /* Same as above */

We also know that the font level variables are specific to their given font family. That means it would be easy enough to create a higher-order mixin that sets those as constants:

@mixin Lato($typeSizeModifier, $typeRowSpan) {
  $latoDescenderHeightScale: 0.11;
  $latoCapHeight: 0.75;
  @include basekick($typeSizeModifier, $typeRowSpan, $latoDescenderHeightScale, $latoCapHeight);
  font-family: Lato;

Now, on a rule basis, we can call the Lato mixin with little fuss:

.heading--medium {
  @include Lato(2, 10);

That output gives us a rule that uses the Lato font with a font-size of 32px and a line-height of 40px with all of the relevant translates and margins. This allows us to write simple style rules and utilize the grid consistency that designers are accustomed to when using tools like Sketch and Figma.

As a result, we can easily create pixel-perfect designs with little fuss. See how well the example aligns to our base 4px grid below. (You’ll likely have to zoom in to see the grid.)

Doing this gives us a unique superpower when it comes to creating layouts on our websites: We can, for the first time in history, actually create pixel-perfect pages. Couple this technique with some basic layout components and we can begin creating pages in the same way we would in a design tool.

Moving toward a standard

While teaching CSS to behave more like our design tools does take a little effort, there is potentially good news on the horizon. An addition to the CSS specification has been proposed to toggle this behavior natively. The proposal, as it stands now, would add an additional property to text elements similar to line-height-trim or leading-trim

One of the amazing things about web languages is that we all have an ability to participate. If this seems like a feature you would like to see as part of CSS, you have the ability to drop in and add a comment to that thread to let your voice be heard.

Why browser showing blank white screen when playing videos? …

I am on chrome. I have the below html5 video tag..

<video id="video" controls="" preload="none">
  <source src="">
  <source src="" type="video/mp4">
  <source src="" type="video/webm">
  <p>Your browser does not support HTML 5 Video</p>

When the page loads, I see audio is coming but the video player is white, no video. Once I remove all the source tag, but keep <source type="video/webm">then the page playing the video as expected. What is wrong with the multiple source inputs like I have?

I edited the URL for not exposing it. So it will be 404. 🙂

Total newbie wanting to do a landing page


Not a coder or anything remotely close to that, so got some rather basic questions for redditors here.

I want to do create a landing page for my friend’s journal app for fun. We have a rough idea of how things are laid out on the landing page:

Post image

Nothing fancy for now. Sorry about the yucky green-yellow color combo. We haven’t decided on the brand colour just yet.

We will need the “Enter email address” and the line underneath to be replaced with “Thanks!” message once visitor clicks on the CTA button. We will also need the social media icons to somehow make it easy for visitors to spread the word – preferably without leaving our website. And if that’s not possible, what’s the standard way to do that?

We are thinking of doing this via Webflow to start, since it might be fun to do some basic coding and trying to customise a template might be harder? Other suggestions on this is welcome. We are going for cost-effective solution here as we are paying out-of-pocket.

Down the line, we will change up the landing page into a website with basics like ‘About’, ‘Contact us’.

So we got a domain. What do we do now? We really need easy step-by-step instructions here.

Thanks so much!

PS. Sorry in advance if we end up seeking more explanation from your comments as we don’t know any webdev terms.
