Web Development + Follow

Since I first chimed in on the CSS4¹ thing, there’s been tons of more discussion on it. I’m going to round up my favorite thoughts from others here. There is an overwhelming amount of talk about this, so I’m going to distill it here down as far as I can, hopefully making it easier to …

The <details> and <summary> elements in HTML are useful for making content toggles for bits of text. By default, you see the <summary> element with a toggle triangle (▶︎) next to it. Click that to expand the rest of the text inside the <details> element. But let’s say you want to be able to click …

One thing that caught my eye on the list of features for Lea Verou’s conic-gradient() polyfill was the last item: Supports double position syntax (two positions for the same color stop, as a shortcut for two consecutive color stops with the same color) Surprisingly, I recently discovered most people aren’t even aware that double position …

Our complete guide to links, buttons, and button-like inputs in HTML, CSS, and JavaScript.

Web development is always changing. One trend in particular has become very popular lately, and it fundamentally goes against the conventional wisdom about how a web page should be made. It is exciting for some but frustrating for others, and the reasons for both are difficult to explain. A web page is traditionally made up …

This article is full of a bunch of data from Aggelos Arvanitakis. But lemme just focus on his final bit of advice: Investigate whether a zero-runtime CSS-in-JS library can work for your project. Sometimes we tend to prefer writing CSS in JS for the DX (developer experience) it offers, without a need to have access …

Storyblok is a headless but component-based CMS with a built-in live-preview. You can use it for building fast and reliable websites and power native apps with your favorite technology. Let us start with the basics and what a headless CMS is: A headless content management system is a back-end only content management system (CMS) built from …

In an article with the most clickbaity article ever, Joe Honton does a nice job of talking about the evolving landscape of web development. “Full-stack” perhaps had its day as a useful term, but since front-end development touches so many parts of the stack now, it’s not a particularly useful term. Joe himself did a …

Hot news from Brian Kardell, regarding what we’ve been referring to as “container queries,” the most hotly requested feature in CSS: There does seem to be some general agreement on at least one part of what I am going to call instead “Responsive Design for Components” and that is that flipping the problem on its …

Sometimes, we have to go a little further than HTML, CSS, and JavaScript to create the UI we need, and instead use other resources, like SVG, WebGL, canvas, and others. For example, the most amazing effects can be created with WebGL, because it’s a JavaScript API designed to render interactive 2D and 3D graphics within any compatible web browser, allowing GPU-accelerated image …

I was sort of making fun of neumorphism the other day. I don’t actually care that much. I mostly just think it only works on some flat colored backgrounds, mostly really light colors, and somehow that feels weirdly limiting. (nope, sure, sure, nope 🤷‍♂️). Anyway, I think this “generator” from Adam Giebl (Adam Gieblio maybe?) …

React Router 5 embraces the power of hooks and has introduced four different hooks to help with routing. You will find this article useful if you are looking for a quick primer on the new patterns of React Router. But before we look at hooks, we will start off with a new route rendering pattern.

Say you have an RSS feed like this one. The goal is to request that RSS feed, parse it, and do something useful with the data in it. RSS is XML, and XML is arguably not as easy to work with than JSON. While a lot of APIs offer JSON responses, it’s less typical for …

Wait what? That’s right, direct access to the files and data storage that power your site on WordPress.com, just like you have if you self-host a WordPress site. You can read their announcement here. Note this is for Business and eCommerce plans only.

It was fun watching a bunch of back and forth blogging between a bunch of smart people quoting a bunch of smart people last week. If you missed it, you might wanna start at the end and work backward. I only have one tidbit to add. I don’t do much with design systems. I work …

On the Microsoft Edge team, we’re committed to an open web and helping to drive innovation forward, which is why we’ve kicked off a new initiative in collaboration with Google, Mozilla, Samsung Internet, Igalia and — most importantly — the web community, called The Web We Want. The Web We Want is an open initiative for web developers and …

Back in 2011, the domain name for this site, css-tricks.com, was stolen. “Domain Hijacking,” they call it. It wasn’t just this site, but around 12 others in the design and development space. To this day, none of us really know how it happened and who was behind it, although I believe all the domains are …

There is a growing number of things that we have to do to help the browser achieve for peak performance. Responsive image syntax has several. For example, needing to tell the browser how large the image will be in our layout with the sizes attribute and how big the images are with w descriptors. Regular …

I mean, kinda. I was just asked this question the other day so I’m answering here because blogging is cool. The point of an RSS feed is for people to read your content elsewhere (hence the last part of the acronym, Syndication, as in, broadcasting elsewhere). Probably an RSS reader. But RSS is XML, so …

Of all the tech-focused year-in-review posts I read, Guillermo Rauch’s is my favorite. There is a lot in there, jumping from topics like modern architectures, high-fiving specific apps, and philosophical movements. I’ll pick one quote about the rise of “deploy previews”: A salient feature is the transition we are seeing away from code review into deployment preview. Code review is …

It’s entirely possible to build custom checkboxes, radio buttons, and toggle switches these days, while staying semantic and accessible. We don’t even need a single line of JavaScript or extra HTML elements! It’s actually gotten easier lately than it has been in the past. Let’s take a look.

I love this post that walks through the development of CSS and HTML — it shows just how far web design has come and how much easier it is for us all now.

public abstract class LiveData extends Object

LiveData je apstraktna klasa tzv. observable data holder zadužen da čuva informacije o podacima i da obavesti sve zainteresovane posmatrače ako dodje do promena. LiveData is actually just an Abstract Class. So it can’t be used as itself. Najvažnija karakteristika LiveData je ta što je svestan životnog ciklusa drugih komponenti aplikacije …

If you have a limited-width container, say a centered column of text, “breaking out” of that to make a full-width element involves trickery. Perhaps the best trick is the one with left relative positioning and a negative left viewport-based margin. While it has its caveats (e.g. requiring hidden overflow on the body, the container needs …

Mike Solomon worked on a fancy scrollytelling post for Esquire and blogged about it. It has GIFs of each step along the way of figuring out not just position: sticky; but also using negative margins, wrapper divs, backgrounds, and even a smidge of JavaScript measuring to get it all right. What it doesn’t have is …

For the last six years, Vue, Angular, and React have run the world of front-end component frameworks. Google and Facebook have their own sponsored frameworks, but they might leave a bitter taste for anyone who advocates for an open and unbiased web. Vue is another popular framework that has multiple sponsors but isn’t run by …

Here’s a great in-depth post from Adam Silver about his journey to create an autocomplete field that’s as accessible as possible. There are so many edge cases to consider! There are old browsers and their peculiar quirks, there are accessibility best practices for screen readers, and not to mention dealing with the component design when …

Whenever a browser upgrades versions, it’s a little marketing event, and rightly so. Looks like for Firefox it’s about once a month, Chrome is ~6 weeks, and Safari is once a year. Chrome 80 just dropped, as they say, and we get a video and blog post. What strikes me about releases like this these …

I’ve been guilty of publicly bemoaning the complexity of HTTPS. In the past, I’ve purchased SSL certificates from third-party vendors and had trouble installing them. I’ve had certificates expire and had to scramble to fix them. I’ve had to poke and prod hosting companies to help me ensure things were going to renew correctly, and …

Interesting research from Aaron Peters on <img loading=”lazy” … >: On my 13 inch macbook, with Dock positioned on the left, the viewport height in Chrome is 786 pixels so images with loading=”lazy” that are more than 4x the viewport down the page are eagerly fetched by Chrome on page load. In my opinion, that is waaaaay …
