CSS Tricks

This is a great explanatory microsite by Sam Richard. CSS Houdini will let authors tap in to the actual CSS engine, finally allowing us to extend CSS, and do so at CSS speeds. Much like Service Workers are a low-level JavaScript API for the browser's cache, Houdini introduces low-level JavaScript APIs for the browser's render engines. What's important to know is that Houdini is broken up into these different parts, each of which will be implemented separately. We have an intro to the paint API here and a number of other articles that touch on it. Here's a very cool collection Dan Wilson put together of Houdini + Custom Properties.

Mike Hartington glows about how good and useful the Shadow DOM is: [Shadow DOM is] actually built on two simple ideas, isolation and location. Need to create a bit of DOM that is isolated from the global scope? Shadow DOM is here to help. Need to specify the exact location of a piece of DOM? Shadow DOMs scope API is what you need! It can be helpful to think of components that use Shadow DOM as modules for HTML. Markup and styles are isolated to their own DOM tree, and removed from the global context. Last time we talked about it around here, I showed how Twitter is using it for embedded tweets — which is a pretty awesome use case — and how it can fall back to an iframe. Mike says they polyfill it in unsupported situations. I suspect isolated styles is the primary selling point for any o...

Most of the behavior in an application revolves around events. User enters a value in the registration form? Event. User hits the submit button? Another event. Events are triggered a number of ways and we build applications to listen for them in order to do something else in response. You may already be super comfortable working with events based on your existing JavaScript experience. However, React has a distinct way of handling them. Rather than directly targeting DOM events, React wraps them in their own event wrapper. But we’ll get into that. Let’s go over how to create, add and listen for events in React. Creating Events We’ll start by creating a form that has an input and a button. An event will be triggered when a value is entered. The button is used to call a function which will ...

I'm very glad a guide for these features exists because we already know there are so many weird things that variable fonts can do — well done, Tunghsiao Liu! There are quite a few possible values for font-feature-settings, like, ya know: aalt, swsh, cswh, calt, hist, hlig, locl, rand, nalt, cv01-cv99, salt, subs, sups, titl, rvrn, liga, dlig, size, ornm, ccmp, kern, mark, mkmk, smcp, c2sc, pcap, c2pc, unic, cpsp, case, ital, ordn, lnum, onum, pnum, tnum, frac, afrc, dnom, numr, sinf, zero, mgrk, flac, dtls, ssty, ss01-ss20, smpl, trad, tnam, expt, hojo, nlck, jp78, jp83, jp90, jp04, hngl, ljmo, tjmo, vjmo, fwid, hwid, halt, twid, qwid, pwid, palt, pkna, ruby, hkna, vkna, rlig, init, medi, and fina ...to name a few.

I got a great email from a fellow named Josh Long the other day. He is, in his words, "relatively new to web design" and was a bit stuck on the concept of getting a site live. I should say that I'm happy to get emails like this an I always read them, but I typically can't offer tech support over email. If I can respond at all, I normally point people to other community resources. In this case, it struck me what a perfect moment this is for Josh. He's a little confused, but he knows enough to be asking a lot of questions and sorting through all this stuff. I figured this was a wonderful opportunity to dig into his questions, hopefully helping him and just maybe helping others in a similar situation. Here's one of the original paragraphs Daniel sent me, completely unedited: I’m relatively ...

Wall Street Journal design director Matthew Ström on something near and dear to me: the link between code and design tools: We’re in the middle of a design tool renaissance. In the 8 years since Sketch 1.0 was released, there’s been a wave of competition among traditional design tools. And as the number of tools available to designers grows exponentially, ideas that were once considered fringe are finding a broader audience. One of these ideas will significantly change the way digital products are designed: integrating design and code at a deep level. Figma can update a React code base in real time; InVision, Abstract, and Zeplin have done away with design-developer handoff documents; Framer’s new Framer X can render interactive React components directly into its workspace. These examples...
