What on Earth is the `types` Descriptor in View Transitions?

by: Juan Diego Rodríguez Wed, 29 Jan 2025 14:13:53 +0000 Have you ever stumbled upon something new and went to research it just to find that there is little-to-no information about it? It’s a mixed feeling: confusing and discouraging because there is no apparent direction, but also exciting because it’s probably new to lots of people, not just you. Something like that happened to me while writing an Almanac’s entry for the @view-transition at-rule and its types descriptor. You may already k

How I am Moving Away From Google's Ecosystem

by: Ankush Das Google's ecosystem includes several products and services. It is one of the prominent ecosystems on the internet with a dominating market share. While I believe their products require no introduction, as a formality, I should mention some of them as Gmail, YouTube, Google Chrome, Google Drive, Google Search, Google Photos, and Google Gemini. Considering I am an Android user, and prioritize my convenience, I have been using Google services for a long time now. However, I have de

Chris’ Corner: JavaScript Ecosystem Tools

Like what technology they use, why, and how, particularly when there are pain points and journeys through them. Jim Simon of Reddit wrote one a bit ago about their teams build process. They were using something Rollup based and getting 2-minute build times and spent quite a bit of time and effort switching to Vite and now are getting sub-1-second build times.

Revisiting CSS Multi-Column Layout

Perhaps because, before the web, I’d worked in print, I was over-excited at the prospect of dividing content into column

Positioning Text Around Elements With CSS Offset

by: Preethi Fri, 24 Jan 2025 14:59:25 +0000 When it comes to positioning elements on a page, including text, there are many ways to go about it in CSS — the literal position property with corresponding inset-* properties, translate, margin, anchor() (limited browser support at the moment), and so forth. The offset property is another one that belongs in that list. The offset property is typically used for animating an element along a predetermined path. For instance, the square in the f

Some Things You Might Not Know About Custom Counter Styles

Or maybe your way of doing things is to wipe out the list-style (caref

21 Jargon Every Linux User Should Know

by: Ankush Das Whether you are a Windows/macOS user, or someone who is new to computers, Linux often comes as a challenge to everyone when they encounter unfamiliar terms. You do not usually come across Linux-specific jargon in standard high school academic computer books, unless there is a dedicated chapter for Linux. So, for the majority of users who never used Linux, the terms associated will sound alien to them. With this article, I aim to change that by explaining some of the important j

Chris’ Corner: HTML

by: Chris Coyier Mon, 20 Jan 2025 16:31:11 +0000 HTML is fun to think about. The old classic battle of “HTML is a programming language” has surfaced in the pages of none other than WIRED magazine. I love this argument, not even for it’s merit, but for the absolutely certainty that you will get people coming out of the woodwork to tell you that HTML, is not, in fact, a programming language. Each of them will have their own exotic and deeply personal reasons why. I honestly don’t even care or bel
