Web Development + Follow

I’ve long been skeptical of quoting global browser usage percentages to justify their usage of browser features. It doesn’t matter what global usage of a browser is, other than nerdy cocktail party fodder. The usage that matters is what users on your site are using, and that can be wildly different from site to site. …

The following is a guest post written by Carlos Schults. Being able to disable code in production is a power that many developers aren’t aware of. And that’s a shame. The ability to switch off some portions—or even complete features—of the codebase can dramatically improve the software development process by allowing best practices that can …

CSS still can’t animate to auto dimensions. There is JavaScript trickery you can try. Brandon Smith outlined several techniques here a little while back. My mind always goes to this solution just because it’s so simple:

Reactivity is one of Vue’s greatest features. It is also one of the most mysterious if you don’t know what it’s doing behind the scenes. Like, why does it work with objects and arrays and not with other things, like localStorage? Let’s answer that that question, and while we’re at it, make Vue reactivity work …

Apple announced a ton of new updates at yesterday’s WWDC20 keynote address, from new hardware to updated applications. There’s lots to gawk at and enough device-envy to go around. But there’s one little line in the Safari 14 Beta release notes that caught my eye: Added WebP image support. 🎉🎉🎉

HTML has an <input type=”range”>, which is, you could argue, the simplest type of proportion slider. Wherever the thumb of that slider ends up could represent a proportion of whatever is before and whatever is after it (using the value and max attributes). Getting fancier, it’s possible to build a multi-thumb slider. But we’ve got …

Scroll-related animations have been used on the web for years. In recent years, they’ve started to become more common, perhaps in part due to devices being higher-performing and thus able to handle more animation.  There are a number of scroll related technologies out there, so this article’s aim is to provide an overview of them …

This is a neat little library. It uses SVG to insert hand-drawn looking annotations to elements (probably text), like underlines and box highlights (there are 6 design options, all configurable). Super clever.

Since the inception of CSS in 1994, the cascade and inheritance have defined how we design on the web. Both are powerful features but, as authors, we’ve had very little control over how they interact. Selector specificity and source order provide some minimal “layering” control, without a lot of nuance — and inheritance requires an …

I remember searching for tutorials for making seamless patterns in Photoshop¹ all the time back in the day. It’s fun to see this little website for building repeating patterns as its one job. It does everything you’d expect: pick a background, drag some decorations onto it and position them (overlapping an edge is fine, which …

The <canvas> element in HTML and Canvas API in JavaScript combine to form one of the main raster graphics and animation possibilities on the web. A common canvas use-case is programmatically generating images for websites, particularly games. That’s exactly what I’ve done in a website I built for playing Solitaire. The cards, including all their …

I’d say 85% of my grid usage is in one of these two categories… I just need some pretty basic (probably equal width) columns that ends up being something like like grid-template-columns: repeat(3, minmax(0, 1fr)); to be safe. Actually doing some real layout where five minutes in I realize I’d really like subgrid. Subgrid? It’s …

The question of how and where to learn HTML & CSS is a highly reasonable thing to ask. The answer depends on all sorts of things: how serious you are, your current foundation, what other resources are available to you, what you hope to do with what you learn, and how much time you have, …

HTTP requests are a crucial part of any web application that’s communicating with a back-end server. The front end needs some data, so it asks for it via a network HTTP request (or Ajax, as it tends to be called), and the server returns an answer. Almost every website these days does this in some …

I think of grids as arrangements of rectangles with vertical and horizontal lines running through. And they are, but that doesn’t mean we can’t still do clever things in how we place things on those grids and what we do with the elements afterwards. In this demo by Jesse Breneman, a grid of hexagons is …

If you were to ask me what question I hear most about front-end development, I’d say it’s“How do I get better at CSS?”. That question usually comes up after sharing a CSS illustration I have made. It’s something I love to do over on CodePen. To many, CSS is this mythical beast that can’t be …

I’ll sometimes search the web for something like “Small Text Generator” knowing there will be some website that will turn some dumb thing I want to type like: into something fun like… Important note about accessibility: This kind of altered text will read terribly with assistive technology like VoiceOver. Just “Uhm” will read as “modified …

As front-end developers, our job is working with browsers. Knowing how many we have and the health of them is always of great interest. As far as numbers go, we have fewer recently than we have in the past. It’s only this month that Edge is starting to auto-update browsers to the Chromium version, yet …

With a very recent Safari update, Web Animations API (WAAPI) is now supported without a flag in all modern browsers (except IE).  Here’s a handy Pen where you can check which features your browser supports. The WAAPI is a nice way to do animation (that needs to be done in JavaScript) because it’s native — …

Developer Experience¹ is a term² with a self-declaring meaning — the experience of developers — but it eludes definition in the sense that people invoke it at different times for different reasons referring to different things. For instance, our own Sarah Drasner’s current job title is “VP of Developer Experience” at Netlify, so it’s a …

Flywheel is my WordPress hosting partner here. I use Local every day for my WordPress local development environment and use their hosting for all my WordPress sites as part of my whole flow, so I’m glad they aren’t just a sponsor but a product I use and like. Last November some of their crew came …

I am creating a WordPress plugin and there is a slight learning curve when it comes to using it. I’d like to give users a primer on how to use the plugin, but I want to avoid diverting users to documentation on the plugin’s website since that takes them out of the experience. What would …

Here’s the plan! We’re going to build a styled select element. Not just the outside, but the inside too. Total styling control. Plus we’re going to make it accessible. We’re not going to try to replicate everything that the browser does by default with a native <select> element. We’re going to literally use a <select> …

There are some neat interactive demos in here from Thiru Manikandan. There are a couple of very tricky things with z-index that never fail to confuse. In addition to things like requiring positioning and source order, the trickiest are the stacking contexts and parent/child relationships. z-index isn’t a flat playing field. Even if you put …

A CSS methodology from Andy Bell: The most important part of this methodology is the language itself: CSS. It’s key to note its existence in the name because some alternative approaches, such as BEM—which I have enjoyed for many years—can veer very far away from Cascading Style Sheets. I love CSS, though and think that its core capabilities …

Here’s a two-second review. If an element has an ID, you can link to it with natural browser behavior. It’s great if headings have them, because it’s often useful to link directly to a specific section of content. Should I be so inclined, I could link right to this heading, be it from an URL, …

I needed a numbered list of blog posts to be listed with the last/high first and going down from there. Like this: But the above is just text. I wanted to do this with a semantic <ol> element.

You can create stripes in CSS. That’s all I thought about in terms of CSS background patterns for a long time. There’s nothing wrong with stripes; stripes are cool. They can be customized into wide and narrow bands, criss-crossed into a checked pattern, and played with in other ways using the idea of hard stops. …

Šime Vidas with the lowdown on what these pseudo-selectors are and why they will be useful: :is() is to reduce repetition¹ of parts of comma-separated selectors. :where() is the same, but nothing inside it affects specificity. The example of wrapping :where(:not()) is really great, as now there is a way to use :not() without bumping …

I discovered CSS about a decade ago while trying to modify the look of a blog I had created. Pretty soon, I was able to code cool things with more mathematical and, therefore, easier-to-understand features like transforms. However, other areas of CSS, such as layout, have remained a constant source of pain. This post is …
