Intrinsically Responsive CSS Grid with minmax() and min()


The most famous line of code to have come out of CSS grid so far is: grid-template-columns: repeat(auto-fill, minmax(10rem, 1fr)); Without any media queries, that will set up a grid container that has a flexible number of columns. The columns will stretch a little, until there is enough room...

Datalist is for suggesting values without enforcing values


Have you ever had a form that needed to accept a short, arbitrary bit of text? Like a name or whatever. That's exactly what <input type="text"> is for. There are lots of different input types (and modes!), and picking the right one is a great idea. But this little story is about something...

JavaScript Proxy with Storage


The JavaScript Proxy API provides a wealth of “magic” within JavaScript, allowing you to use any object as sort of an alias that allows a wall of validation, formatting, and error throwing. Did you know that you could also employ the Proxy API as an abstraction to different types...

Responsive Iframes


Say you wanted to put the CSS-Tricks website in an <iframe>. You'd do that like this: <iframe src="https://css-tricks.com"></iframe> Without any other styling, you'd get a rectangle that is 300x150 pixels in size. That's not even in the User Agent stylesheet, it's just some...

Zdog


David DeSandro has loads of super cool JavaScript libraries he's created over the years. His latest is Zdog, a "round, flat, designer-friendly pseudo-3D engine for canvas & SVG." It's only been about a month since he dropped it (although, like any good library, it's been simmering) and it...

Don’t comma-separate :focus-within if you need deep browser support


I really like :focus-within. It's a super useful selector that allows you to essentially select a parent element when any of its children are in focus. Say you wanted to reveal some extra stuff when a <div> is hovered... div:hover { .extra-stuff { /* reveal it */ } } That's...

My New Mac Setup and Why I Switched


I want to start this article by saying that I'm not here to start or take part in any brand war between Microsoft and Apple. I like both companies and have switched between operating systems occasi

Pseudo Code


Yonatan Doron wrote a post on Medium not long ago called "Art of Code — Why you should write more Pseudo Code." Love that title, as a fan of pseudo code myself. That is, writing "code" that describes something you want to do or communicate, but that isn't of any particular language and doesn't...

CSS :not() with Multiple Classes


Say you want to select an element when it doesn't have a certain class. That's what the :not() selector is for. body:not(.home) { } But what if there are multiple classes you want to avoid? There are no logical combinators with :not(), like and or or, but you can chain them, which...

Using GraphQL Playground with Gatsby


I’m assuming most of you have already heard about Gatsby, and at least loosely know that it’s basically a static site generator for React sites. It generally runs like this: Data Sources → Pull data from anywhere. Build → Generate your website with React and GraphQL. Deploy → Send the site to...

Get Peak WordPress Performance with Jetpack


The irony of web performance is that the average page weight of a site continues to go up year after year, despite us being more aware of the problem and having more tools at our disposal to fight it than ever. To paraphrase Seinfeld, "we know how to fight page weight issues; we just don't use...

Finally… A Post on Finally in Promises


“When does finally fire in a JavaScript promise?” This is a question I was asked in a recent workshop and I thought I’d write up a little post to clear up any confusion. The answer is, to quote Snape: ...always. The basic structure is like this: try { // I’ll try to execute some code...

JP Morgan Chase Ship Busted: Cocaine, Banks and the Failed Drug War


A ship seized by the U.S. Customs and Border Protection Agency in June carrying over 15,000 kilos of cocaine has now been tied to JP Morgan Chase’s asset management unit. Officially the company does not exercise any operational control of the vessel, but some serious questions are raised when...

Exploring Sets and Maps in JavaScript


Let’s take a look into two new constructs that were introduced in the JavaScript ES6 specification: Set - The Set object allows you to store unique values of any type

Toast


One day, all the sudden, I started hearing jokes about toast. I had no idea what the context was. I assumed some friends just got started telling toast jokes, which isn't rare by any means. But it turns out it was a whole thing. It got me thinking, jeez, if I can't keep up with this stuff when it's...
