CSS2JS

To add inline styles on an element in JSX, you have to do it in this object syntax, like:
<div style={{
fontSize: 16,
marginBottom: "1rem"
}}Content
</div
That might look a little weird to us folks who are so used to the CSS syntax, where it is font-size (not fontSize), margin-bottom...

CSS X
17.3.2020
My name appears in an article from Bert Bos (co-author of the original CSS spec), so I'll consider that a life accomplishment. Berts makes the point that CSS has evolved and the working group versions things, but the working group hasn't been and doesn't really plan to be involved in these...

A <select> menu
An ARIA Listbox, Combobox, Menu, or Disclosure Widget
An input with a <datalist>
An input with autocomplete
A <details><summary> block
An accordion
Flyout navigation
In my own usage, I tend to mean...

13.3.2020
Lara Schenck:
[...] with WordPress child themes, you are all but guaranteed to get into the weeds of specificity, hunting around theme stylesheets that you didn’t author, trying to figure out what existing declaration is preventing you from applying a new style, and then figuring out the least...

In this post, Sarah Chima walks us through how we can work with browser events, such as clicking, using JavaScript. There’s a ton of great info in here! If JavaScript isn’t your strong suit, I think this is the best explanation of event handling that I’ve read in quite some time.

Two Steps Forward, One Step Back
12.3.2020
Brent Jackson says CSS utility libraries failed somewhat:
Eventually, you'll need to add one-off styles that just aren't covered by the library you're using, and there isn't always a clear way to extend what you're working with. Without a clear way to handle things like this, developers tend...

Sass !default and themeable design systems
11.3.2020

background-color: $form-background-color;
padding: 10px
}
If the $form-background-color variable isn’t defined then...

As we noted in our complete guide, you can put an <a href=""> link around whatever chunks of HTML you like. Let's call that a "block link." Like you are wanting to link up an entire "Card" of content because it makes a big clickable target.
<a href="/article/"<!-- display: block;...
Negative Margins
9.3.2020
PPK digs into the subject, which he found woefully undercovered in web tech documentation. Our entry doesn't mention them at all, which I'll aim to fix.
Agree on this situation:

Use a:visited in your CSS stylesheet
9.3.2020
Evert Pot:
Unfortunately, when setting a new color (e.g. a { color: #44F }) the ‘purple visited link’ feature also gets disabled. I think this is a shame, as there’s so many instances where you’re going through a list of links and want to see what you’ve seen before.
