Socket “Socket” predstavlja krajnju tačku za slanje ili primanje podataka u mreži. Drugim rečima, to je interfejs između aplikacije i mrežne komunikacije na operativnom sistemu. Kroz sokete, aplikacije mogu komunicirati međusobno preko mreže. Soketi su osnova za mnoge mrežne aplikacije i usluge, uključujući veb pretraživače, e-mail klijente, chat aplikacije i mnoge druge. Oni omogućavaju komunikaciju …

These things called passkeys sure are making the rounds these days. They were a main attraction at W3C TPAC 2022, gained support in Safari 16, are finding their way into macOS and iOS, and are slated to be the future for password managers like 1Password. They are already supported in Android, and will soon find their way into Chrome OS and Windows in …

I spend a lot of time in DevTools, and I’m sure you do too. Sometimes I even bounce between them, especially when I’m debugging cross-browser issues. DevTools is a lot like browsers themselves — not all of the features in one browser’s DevTools will be the same or supported in another browser’s DevTools. But there …

Doing a quick search here on CSS-Tricks shows just how many different ways there are to approach calendars. Some show how CSS Grid can create the layout efficiently. Some attempt to bring actual data into the mix. Some rely on a framework to help with state management. There are many considerations when building a calendar …

You know what it’s like to pick up a new language or framework. Sometimes there’s great documentation to help you find your way through it. But even the best documentation doesn’t cover absolutely everything. And when you work with something that’s new, you’re bound to find a problem that doesn’t have a written solution. That’s …

CSS trigonometry functions are here! Well, they are if you’re using the latest versions of Firefox and Safari, that is. Having this sort of mathematical power in CSS opens up a whole bunch of possibilities. In this tutorial, I thought we’d dip our toes in the water to get a feel for a couple of …

Fonts are a defining characteristic of the design of any site. That includes WordPress themes, where it’s common for theme developers to integrate a service like Google Fonts into the WordPress Customizer settings for a “classic” PHP-based theme. That hasn’t quite been the case for WordPress block themes. While integrating Google Fonts into classic themes …

I was reading “Creative List Styling” on Google’s web.dev blog and noticed something odd in one of the code examples in the ::marker section of the article. The built-in list markers are bullets, ordinal numbers, and letters. The ::marker pseudo-element allows us to style these markers or replace them with a custom character or image. …

We’re fans of Custom Elements around here. Their design makes them particularly amenable to lazy loading, which can be a boon for performance. Inspired by a colleague’s experiments, I recently set about writing a simple auto-loader: Whenever a custom element appears in the DOM, we wanna load the corresponding implementation if it’s not available yet. …

It’s a question I hear asked quite often: Is it possible to create shadows from gradients instead of solid colors? There is no specific CSS property that does this (believe me, I’ve looked) and any blog post you find about it is basically a lot of CSS tricks to approximate a gradient. We’ll actually cover …

Every now and then, a one blog post is published and it spurs a reaction or response in others that are, in turn, published as blogs posts, and a theme starts to emerge. That’s what happened this past week and the theme developed around the cost of JavaScript frameworks — a cost that, in this …

We often think of background images as texture or something that provides contrast for legible content — in other words, not really content. If it was content, you’d probably reach for an <img> anyway, accessibility and whatnot. But there are times when the position or scale of a background image might sit somewhere between the …

Geez, leave it to Patrick Brosset to talk CSS performance in the most approachable and practical way possible. Not that CSS is always what’s gunking up the speed, or even the lowest hanging fruit when it comes to improving performance. But if you’re looking for gains on the CSS side of things, Patrick has a …

I used to have this boss who loved, loved, loved, loved to emphasize words. This was way back before we used a WYSIWYG editors and I’d have to handcode that crap. (Let’s not go into the colors he used for even MOAR emphasis.) Writing all that markup never felt great. The effort it took, sure, …

Do you know that kind of effect where someone’s head is poking through a circle or hole? The famous Porky Pig animation where he waves goodbye while popping out of a series of red rings is the perfect example, and Kilian Valkhof actually re-created that here on CSS-Tricks a while back. I have a similar …

My previous post was a broad overview of SvelteKit where we saw what a great tool it is for web development. This post will fork off what we did there and dive into every developer’s favorite topic: caching. So, be sure to give my last post a read if you haven’t already. The code for …

Tucked down somewhere in the Safari Technology Preview 161 release notes is a seemingly innocous line about support for a new HTML element and attribute: Added support for <model src> and honor <source type> attributes (257518@main) Anytime I see mention of some element I don’t recognize, my mind goes straight to Huh! New to me, but probably old news …

I’m pleased to shine a light on the fact that the CSS grid-template-rows and grid-template-columns properties are now animatable in all major web browsers! Well, CSS Grid has technically supported animations for a long time, as it’s baked right into the CSS Grid Layout Module Level 1 spec. But animating these grid properties only recently …

SvelteKit is the latest of what I’d call next-gen application frameworks. It, of course, scaffolds an application for you, with the file-based routing, deployment, and server-side rendering that Next has done forever. But SvelteKit also supports nested layouts, server mutations that sync up the data on your page, and some other niceties we’ll get into. …

The :has() pseudo-class is, hands-down, my favorite new CSS feature. I know it is for many of you as well, at least those of you who took the State of CSS survey. The ability to write selectors upside down gives us more superpowers I’d never thought possible. I say “more superpowers” because there have already …

While I am not a regular Chrome extension programmer, I have certainly coded enough extensions and have a wide enough web development portfolio to know my way around the task. However, just recently, I had a client reject one of my extensions as I received feedback that my extension was “outdated”. As I was scrambling …

If you’ve ever worked on sites with lots of long-form text — especially CMS sites where people can enter screeds of text in a WYSIWYG editor — you’ve likely had to write CSS to manage the vertical spacing between different typographic elements, like headings, paragraphs, lists and so on. It’s surprisingly tricky to get this …

Someone recently asked me how I approach debugging inline SVGs. Because it is part of the DOM, we can inspect any inline SVG in any browser DevTools. And because of that, we have the ability to scope things out and uncover any potential issues or opportunities to optimize the SVG. But sometimes, we can’t even …

A little thing happened on the way to publishing the CSS :has() selector to the ol’ Almanac. I had originally described :has() as a “forgiving” selector, the idea being that anything in its argument is evaluated, even if one or more of the items is invalid. See ::scoobydoo in there? That’s totally invalid. A forgiving …

The good ol’ <table> tag is the most semantic HTML for showing tabular data. But I find it very hard to control how the table is presented, particularly column widths in a dynamic environment where you might not know how much content is going into each table cell. In some cases, one column is super …

A little while back, Ganesh Dahal penned a post here on CSS-Tricks responding to a tweet that asked about adding CSS box shadows on WordPress blocks and elements. There’s a lot of great stuff in there that leverages new features that shipped in WordPress 6.1 that provide controls for applying shadows to things directly in …

You know, this is the time of year where Chris normally publishes a big ol’ reflection of the past year. The first one was published in 2007, the same year CSS-Tricks began, and it continued all the way through 2021 without missing a beat. Having been a CSS-Tricks reader myself all those years, I’d hate …

We’ve started making a tradition of rounding up the latest front-end research at the end of each year. We did it in 2020 and again in 2021. Reports are released throughout the year by a bunch of different companies and organizations researching everything from web design trends to developer skills to popular coding languages and …

CSS Nesting is making the rounds yet again. Remember earlier this year when Adam and Miriam put three syntax options up for a vote? Those results were tallied and it wasn’t even even close. Now there’s another chance to speak into the future of nesting, this time over at the WebKit blog. The results from …

Being able to quickly spin up a WordPress instance has been the strength of WordPress ever since its famous “five-minute install”. Upload a few files, configure a few settings, and you’re off. The friction of uploading files has gotten a lot easier, thanks to plenty of “one-click” install options many hosts offer (including DigitalOcean and …
