What does the ‘h’ stand for in Vue’s render method?
30.5.2018
If you’ve been working with Vue for a while, you may have come across this way of rendering your app — this is the default in the latest version of the CLI, in main.js:
new Vue({
render: h => h(App)
}).$mount('#app')
Or, if you’re using a render function, possibly to take advantage...

Learning Gutenberg: React 101
23.5.2018
Although Gutenberg is put together with React, the code we’re writing to make custom blocks isn’t. It certainly resembles a React component though, so I think it’s useful to have a little play to get familiar with this sort of approach. There’s been a lot of reading in this series so far, so let’s...
Unicode Patterns
18.5.2018
These Unicode patterns by Yuan Chuan are extraordinarily clever. It's a <css-doodle> custom web component that sets up a CSS grid and randomizes what character to drop into a cell and things, like color.
See all their gorgeous work on CodePen and the very cool <css-doodle> website...
Custom List Number Styling
18.5.2018
How about a classic CSS trick! This isn't even so tricky anymore, since CSS has counter-increment and counter-reset and such that is perfect for this. I just wanted to make sure you knew how it works and had some easy-to-copy examples at the ready.
Let's say all you wanna do is style the dang...

How React Reconciliation Works
17.5.2018
React is fast! Some of that speed comes from updating only the parts of the DOM that need it. Less for you to worry about and a speed gain to boot. As long as you understand the workings of setState(), you should be good to go. However, it’s also important to familiarize yourself with how this...
Responsive tables, revisited
16.5.2018
Lea Verou with some extra super fancy CSS trickery. No way we could miss linking this one up!
One of the problems with responsive table solutions, at least the ones where you are using CSS to rejigger things, is that there is duplicated content somewhere. Either in CSS or HTML.
Lea finds two ways...
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...
It All Started With Emoji: Color Typography on the Web
15.5.2018
“Typography on the web is in single color: characters are either black or red, never black and red …Then emoji hit the scene, became part of Unicode, and therefore could be expressed by characters — or “glyphs” in font terminology. The smiley, levitating businessman and the infamous pile...
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...

There are a variety of "buttons" in HTML. You've got:
<button>Button</button>

Grid Level 2 and Subgrid
8.5.2018
I find the concept of subgrid a little hard to wrap my mind around.
I do understand the idea that we want to use nested semantic markup as we like and have elements participate in one grid so we don't have to flatten our markup just for layout reasons. But that is largely handled by display:...
