The Ultimate Guide to JavaScript Algorithms: Counting the Vowels in a String of Text
23.1.2019
In this challenge, we will be working with strings and arrays. Strings and arrays are very much alike in that they are both collections of elements usually of the same type.

2019 CSS Wishlist
17.1.2019
What do you wish CSS could do natively that it can't do now? First, let's review the last time we did this in 2013.
❌ "I'd like to be able to select an element based on if it contains another particular selector"
❌ "I'd like to be able to select an element based on the content...
Algorithmic Layouts
10.1.2019
Don't miss this video by Heydon that digs into CSS layouts. It's great how he combines fundamental knowledge, like the way elements flow, wrap, and can have margin with new layout methods like flexbox and grid (with specific examples). Of particular note is the clear demonstration of how flexbox...
The Elements of UI Engineering
4.1.2019
I really enjoyed this post by Dan Abramov. He defines his work as a UI engineer and I especially like what he writes about his learning experience:
My biggest learning breakthroughs weren’t about a particular technology. Rather, I learned the most when I struggled to solve a particular UI problem....
People Talkin’ Shapes
22.12.2018
Codrops has a very nice article on CSS Shapes from Tania Rascia. You might know shape-outside is for redefining the area by which text is floated around that element, allowing for some interesting design opportunities. But there are a couple of genuine CSS tricks in here:
Float shape-outside...
Regarding CSS’s Global Scope
20.12.2018
html {
font-family: Roboto, sans-serif;
}
With the except of some form elements, you've just set a font on every bit of text on a site! Nice! That's probably what you were trying to do, because of the probably hundreds of elements all over your site, setting that font-family every time would...
JavaScript waitForever
10.12.2018
Writing mochitests for new features in DevTools can be difficult and time-consuming. There are so many elements interacting in an async manner that I oftentimes find myself using the debugger to debug the debugger! In the case where it’s unclear what interaction isn’t working...
An Introduction and Guide to the CSS Object Model (CSSOM)
10.12.2018
If you've been writing JavaScript for some time now, it's almost certain you've written some scripts dealing with the Document Object Model (DOM). DOM scripting takes advantage of the fact that a web page opens up a set of APIs (or interfaces) so you can manipulate and otherwise deal with elements...

Adding Particle Effects to DOM Elements with Canvas
23.7.2018
Let’s take a look at how to make web pages more visually capable by combining the freedom of <canvas> with HTML elements. Specifically, we will be creating a basic HTML-to-particle effect, but the same technique could be used for many kinds of effects.
Before we begin, feel free to grab...
8 Digit Hex Colors
16.7.2018
One of the most requested capabilities in my early days of web development was the ability to set opacity on elements and even PNG images without the need for browser-specific CSS or hacks. Eventually we got native opacity support and even enjoyed rgba(), the ability to cite an opacity level with...
WDRL — Edition 235: Colorblind, Grid in IE, Service Worker Quota and Extending Native DOM Elements
13.7.2018
Hey,
The web continues to amaze me. With all its variety and different changes to the platform it’s hard to see a straight pattern, if there’s even (just) one. But it’s wonderful to see what is being changed, which features are added to the platform, which ones get deprecated, and how browsers...
Unused
11.7.2018
I recently wrote Here’s the thing about "unused CSS" tools, where I tried to enumerate all the challenges any tool would have in finding truly "unused" CSS. The overarching idea is that CSS selectors match elements in the DOM, and those elements in the DOM come from all sorts of places: your static...
Random Day in the Life of a Developer
11.7.2018
Yesterday, I started going through my email as soon as I got to work. I always start my day with email. I kinda like email. I read some interesting things in keeping up with the industry. I deal with some business things. I handle with some personal things. I make a note of the most important stuff...
Drawing Images with CSS Gradients
25.6.2018
What I mean by "CSS images" is images that are created using only HTML elements and CSS. They look as if they were SVGs drawn in Adobe Illustrator but they were made right in the browser. Some techniques I’ve seen used are tinkering with border radii, box shadows, and sometimes clip-path. You...

The backdrop-filter CSS property
16.5.2018
I had never heard of the backdrop-filter property until yesterday, but after a couple of hours messing around with it I’m positive that it’s nothing more than magic. This is because it adds filters (like changing the hue, contrast or blur) of the background of an element without changing the text...
How to Get a React Component’s Element
14.5.2018
JSX is an amazing pseudo-language for React, and if I’m honest, it’s what brought me to love React so much. Using React without JSX is cumbersome and frustrating, while using JSX is such an easier way to express your code. One drawback of JSX, however, is that it makes accessing...
Overriding Default Button Styles
9.5.2018
There are a variety of "buttons" in HTML. You've got:
<button>Button</button>
<input type="button" value="Button">
Plus, for better or worse, people like having links that are styled to match the look of other true buttons on the site
<a href="#0"...
