Web Development + Follow

I love shapes, especially colorful ones! Shapes on websites are in the same category of helpfulness as background colors, images, banners, section separators, artwork, and many more: they can help us understand context and inform our actions through affordances. A few months back, I built an application to engage my 7-year old daughter with mathematics. …

Stefan Judis notes that there is a spec for custom media queries, but seemingly no momentum on it at the moment. That lack of movement is unfortunate, as it’s almost guaranteed front-end developers all over would start using it as soon as it’s ready. I know I would, as I liberally use custom properties now, …

When requirements read “when visible” your brain should go straight to IntersectionObserver. That’s exactly what Zach is doing here to kick off an animation when it scrolls into view. Except this animation is an SVG SMIL animation: an <animate> situation. SMIL animations have some kinda cool things they can do, like begin when another animation …

I did a sponsored video the other week explaining how to build a paid subscription newsletter using WordPress (we did it on WordPress.com but it could be hosted anywhere), MailPoet (a plugin to visually author the emails, as well as send them), and WooCommerce (to manage the payments and subscriptions). I published the video here …

Variable fonts make it easy to create a large set of font styles from a single font file. Unfortunately, the default rendering of the <b> and <strong> elements in browsers today is not very compatible with the wide range of font-weight values enabled by variable fonts.

There is a working draft spec for CSS scoping now. Other than a weird period where <style scoped> shipped and then was subsequently removed from the spec (and browsers), this is the furthest a scoping proposal has gotten (the Level 1 spec never got anywhere). This one comes from Miriam Suzanne. The basics: If I’m …

I’d say cloud functions are one of the most transformative technologies in the last bunch of years. They are (usually) cheap, scale well, secure in their inherent isolation, and often written in JavaScript—comfortable territory for front-end developers. Nearly every cloud provider offers them, but AWS Lambda was the OG and remains the leader. But also: …

We’ve already discussed how creating web components is easier than you think, but there’s another aspect of the specification that we haven’t discussed yet and it’s a way to customize (nay, supercharge) a built-in element. It’s similar to creating fully custom or “autonomous” elements — like the <zombie-profile> element from the previous articles—but requires a few differences. …

HTTP Caching is a Superpower — Hugh Haworth covers how the Cache-Control header is an awfully potent ingredient in web performance. I mis-read the title at first and was waiting to read about HTML caching. Hugh covers it a bit (like how you’d need to be careful doing so on something like a forum, where …

Have you ever fretted that front-end web development moves so fast that if you stepped away for a while, you’d be lost coming back? Rachel Smith has: The hectic pace of needing to learn one thing after the next didn’t bother me so much because when I was 26 because I was quite happy to …

Zach did that thing where each of his blog posts has a special URL with the design of social image card that is screenshat by a headless browser (like Puppeteer) and used as a true meta Open Graph image, meaning it’s displayed on Twitter, Facebook, iMessage, Slack, Discord, and whatever else supports that card look.

Static site generators are popular for their speed, security, and user experience. However, sometimes your application needs data that is not available when the site is built. React is a library for building user interfaces that helps you retrieve and store dynamic data in your client application.  Fauna is a flexible, serverless database delivered as …

Nathan Hardy shares when things “clicked”: Reflecting back on this time, I think there are a few key concepts that were vital to things finally all making sense and fitting together. These were: • The Box Model (e.g. box-sizing, height, width, margin, padding)• Layout (e.g. display)• Document Flow and Positioning (e.g. position, top, left, etc.) I called this my ah-ha moment a few years …

All-things-typography, from a hard-edged monospaced variable font to fonts in the “Twilight Zone” … and much, much more.

I think this is good advice from Silvestar Bistrović: An enabling selector is what I call a selector that does a job without disabling the particular rule. The classic example is applying margin to everything, only to have to remove it from the final element because it adds space in a place you don’t want.

You know like https:? That’s a URL Scheme. You’re probably familiar with the concept, thanks to others that come up in front-end development, like mailto:. You can actually make your own, which is pretty cool. There are a lot of them. I find that custom URL schemes come up the most with apps that are …

A bonafide CSS trick if there ever was one! @ShadowShahriar created a CodePen demo that uses pseudo-elements to place commas between list items that are displayed inline, and the result is a natural-looking complete sentence with proper punctuation.

After the fragmentation effect, I am going to tackle another interesting animation: the blob! We all agree that such effect is hard to achieve with CSS, so we generally reach for SVG to make those gooey shapes. But now that the powerful Paint API is available, using CSS is not only possible, but maybe even …

That’s a heartwrenching title from Michael Williamson. I believe it though. It’s kinda like a maximized version of the blogging phenomenon where if you work on a post for weeks it’ll flop compared to a post that’s some dumb 20-minute thought. Or how your off-handed remark to some developer at the perfect time might cause …

What options do you have if you want the body background in a fixed position where it stays put on scroll? background-attachment: fixed in CSS, at best, does not work well in mobile browsers, and at worst is not even supported by the most widely used mobile browsers. You can ditch this idea completely and …

When I think about what front-end development really is and feels like, this is at the heart of it: designing around a huge set of unknowns, and really embracing that notion as a strength of the web rather than a weakness or unfortunate truth we have to work around. Cathy Dutton digs into this with …

The perfect link — Rian Rietveld defines them: “When you click on them, they take you somewhere else.” Not much code in here (we’ve got that), just a lot of practical accessibility advice. For example, the alt text for a linked image can allude to the fact that it is a link. Just an image: …

While learning Vue.js, I started building free web tools that involved the exploration of SVG, with the goal of learning something about both! Let’s take a look at one of those tools: a generator that makes SVG loaders and lets you choose between SMIL or Sass animation, different styles, colors, shapes, and effects. It even …

A question: If you copy a code sample that uses two-space indentation and you want to convert it to four-space indentation, what’s the *fastest* and easiest option? Matt Stauffer, Twitter I wrote about doing this in Sublime Text a few years back. It’s not terribly different in VS Code, I don’t think. But here’s another …

Today’s websites are overflowing with animations—often too many. They get in the way of the content and slow down our busy users. But at the same time: they’re wonderful. They bring websites to life, are fun to implement and can be incredibly impressive to show off. I think they’re great. Sorry impatient users. The way …

This is a bit of advice for developers on Macs I’ve heard quite a few times, and I’ll echo it: go into System Preferences > General > Show scroll bars and set to always. This isn’t about you, it’s about the web. See, the problem is that without this setting on, you’ll never experience scrollbar-triggered …

Free event hosted by Netlify coming up next week (Wednesday, August 25th): Architecting with Next.js. It’s just a little half-day thing. No brainer. Join us for a special event where we’ll highlight business teams using Next.js in production, including architecture deep dives, best practices and challenges. Next.js is the fastest-growing framework for Jamstack developers. With …

Solid is a reactive JavaScript library for creating user interfaces without a virtual DOM. It compiles templates down to real DOM nodes once and wraps updates in fine-grained reactions so that when state updates, only the related code runs. This way, the compiler can optimize initial render and the runtime optimizes updates. This focus on …

You can’t just do @media (prefers-reduced-data: no-preference) alone because, as Kilian Valkhof says: … that would be false if either there was no support (since the browser wouldn’t understand the media query) or if it was supported but the user wanted to preserve data. Usually @supports is the tool for this in CSS, but that doesn’t work …

We can update the URL in JavaScript. We’ve got the APIs pushState and replaceState: JavaScript is also capable of replacing any content in the DOM. So with those powers combined, we can build a website where we navigate to different “pages” but the browser never refreshes. That’s literally what “Single Page App” (SPA) means.
