New in Chrome: CSS Overview
1.7.2020
Here’s a fancy new experimental feature in Chrome! Now, we can get an overview of the CSS used on a site, from how many colors there are to the number of unused declarations… even down to the total number of defined media queries.
Again, this is an experimental feature. Not only does that...
Responsive Styling Using Attribute Selectors
30.6.2020
One of the challenges we face when implementing class-based atomic styling is that it often depends on a specific breakpoint for context.
<div class="span-12"</div<!-- we want this for small screens --<div class="span-6"</div<!-- we want this for medium screens --<div...
When Sass and New CSS Features Collide
29.6.2020
Recently, CSS has added a lot of new cool features such as custom properties and new functions. While these things can make our lives a lot easier, they can also end up interacting with preprocessors, like Sass, in funny ways.
So this is going to be a post about the issues I’ve encountered...
Quick Tips for High Contrast Mode
27.6.2020
Sarah Higley has some CSS tricks up her sleeve for dealing with High Contrast Mode on Windows, which I learned is referred to as WHCM.
Here’s the first trick:
[…] if the default CSS outline property doesn’t give you the visual effect you want [in WHCM] for focus states...
Line-Animated Hamburger Menu
26.6.2020
This kind of SVG + CSS animation trickery is catnip to me. Mikael Ainalem shares how to draw a hamburger icon (the “three lines” thing you’re well familiar with), but then animate it in a way that is surprising and fun by controlling the SVG properties in CSS.

How to Disable Code: The Developer’s Production Kill Switch
25.6.2020
The following is a guest post written by Carlos Schults.
Being able to disable code in production is a power that many developers aren’t aware of. And that’s a shame. The ability to switch off some portions—or even complete features—of the codebase can dramatically improve the software development...
Hide Scrollbars During an Animation
24.6.2020
CSS still can’t animate to auto dimensions.
.dropdown {
transition: 0.2s;
height: 0;
}
.dropdown.open {
/* the height will change, but it won't animate. */
height: auto;
}
There is JavaScript trickery you can try. Brandon Smith outlined several techniques here a little while back....
How to Make localStorage Reactive in Vue
24.6.2020
Reactivity is one of Vue’s greatest features. It is also one of the most mysterious if you don’t know what it’s doing behind the scenes. Like, why does it work with objects and arrays and not with other things, like localStorage?
Let’s answer that that question, and while we’re at it, make...
Let’s Make a Multi-Thumb Slider That Calculates The Width Between Thumbs
23.6.2020
HTML has an <input type="range">, which is, you could argue, the simplest type of proportion slider. Wherever the thumb of that slider ends up could represent a proportion of whatever is before and whatever is after it (using the value and max attributes). Getting fancier, it’s possible...
Rough Notation
22.6.2020
This is a neat little library. It uses SVG to insert hand-drawn looking annotations to elements (probably text), like underlines and box highlights (there are 6 design options, all configurable). Super clever.
Here’s a little demo:

Aside from it just being cool,...
Easing Animations in Canvas
19.6.2020
The <canvas> element in HTML and Canvas API in JavaScript combine to form one of the main raster graphics and animation possibilities on the web. A common canvas use-case is programmatically generating images for websites, particularly games. That’s exactly what I’ve done in a website...
Just another +1 for subgrid
19.6.2020
I’d say 85% of my grid usage is in one of these two categories…
I just need some pretty basic (probably equal width) columns that ends up being something like like grid-template-columns: repeat(3, minmax(0, 1fr)); to be safe.
Actually doing some real layout where five minutes in...
Blockchain Code Can Fill In When Antitrust Law Fails
17.6.2020
Technology and the law have traditionally been at odds, but with blockchain and antitrust policy there's potential for cooperation
LingoJam

I’ll sometimes search the web for something like “Small Text Generator” knowing there will be some website that will turn some dumb thing I want to type like:
Uhm hi when is that meeting again?
into something fun like…

Striking a Balance Between Native and Custom Select Elements
12.6.2020
Here’s the plan! We’re going to build a styled select element. Not just the outside, but the inside too. Total styling control. Plus we’re going to make it accessible. We’re not going to try to replicate everything that the browser does by default with a native <select> element. We’re going...
Learn Z-Index Using a Visualization Tool
12.6.2020
There are some neat interactive demos in here from Thiru Manikandan. There are a couple of very tricky things with z-index that never fail to confuse. In addition to things like requiring positioning and source order, the trickiest are the stacking contexts and parent/child relationships. z-index...
On Adding IDs to Headers
11.6.2020
Here’s a two-second review. If an element has an ID, you can link to it with natural browser behavior. It’s great if headings have them, because it’s often useful to link directly to a specific section of content.
<h3 id="step-2"Step 2</a
Should I be so inclined, I could...
How to Reverse CSS Custom Counters
11.6.2020
I needed a numbered list of blog posts to be listed with the last/high first and going down from there. Like this:
5. Post Title
4. Post Title
3. Post Title
2. Post Title
1. Post Title
But the above is just text. I wanted to do this with a semantic <ol> element.
The easy way
This can...
Kotlin Coroutines and Delay
11.6.2020
Whenever I suspect that there’s a timing conflict causing a problem with rendering and directives, I usually opt for a JavaScript setTimeout with a delay. The setTimeout code never makes it to production, but it does help me to understand if my code is the problem or if there’s a timing...
CSS :is() and :where() are coming to browsers
10.6.2020
Šime Vidas with the lowdown on what these pseudo-selectors are and why they will be useful:
:is() is to reduce repetition¹ of parts of comma-separated selectors.
:where() is the same, but nothing inside it affects specificity. The example of wrapping :where(:not()) is really great, as now there...
