By Ilya Grigorik on September 16, 2014 A "webfont" is a set of resources, not just a single download. A single resource that includes all stylistic variants, which we may not need, plus all the characters, which may go unused, would simply be too large — tens of megabytes for a font with good unicode and stylistic coverage! As a result, the CSS @font-face rule allows us define a font family that i
This is the written version of my new talk, “Keeping it simple with CSS that scales”, which I first delivered at State of the Browser 2019. It’s a very long read, so I recorded an audio version, too: CSS has a weird place on the web today. There’s a lot of polarisation, with the opinion being seemingly split on “CSS sucks” and “CSS rules, learn it better, fools”. I empathise with the “CSS rules” c
Default Smooth As light hits an object and a shadow is cast, the shadow can take on a myriad of unique characteristics. If you try to capture the subtleties of a real shadow with box-shadow then, well, you’re pretty much out of luck. The box-shadow CSS property isn’t exactly built to encourage expressiveness. It essentially produces a blurred silhouette of an object—you can change its offset, blur

Since you may not have a lot of time, I’m going to start at the end, with the dessert. You can use a little-known, yet important and powerful CSS property to make text run vertically. Like this. Or instead of running text vertically, you can layout a set of icons or interface buttons in this way. Or, of course, with anything on your page. The CSS I’ve applied makes the browser rethink the orientat
Yep, let’s talk about the CSS property vertical-align. It’s intended use is to align text and elements next to each other. Like centering an icon next to a bit of text. But, it can be a real scumbag sometimes with all its seemingly mysterious rules at work. For example, it might happen, that the element you changed vertical-align for doesn’t change its alignment at all, but other elements next to
Deleted articles cannot be recovered. Draft of this article would be also deleted. Are you sure you want to delete this article? 先日、 ブラウザ君「ワイはCSSのセレクタを右から読むんや」 という記事を読みまして、ちょっと気になったので後で確かめようと思っていたのですが、なんとなくそのままになってしまいやや旬を逃した感がありつつ、ツッコミを入れてみようと思います。 なお『ワイ「ほげほげ」』みたいな形式は使いません1。恥ずかしいので。 私は仕事でChromiumのソースコードをよく読んでいるので、ChromiumのソースコードからCSSの処理を見つけて、それを基準にして解説しようと思います2。そのため、他のブラウザのレンダリングエンジンと異なる最適化が施されている
This post has been updated to reflect the situation as of January 2023, and subsequently June 2024. Changes include additional support in Chrome, along with the regression for support in Edge, which used to support all the hyphenation properties (the only browser to do so) but lost this capability with its switch to Blink in 2020 (Edge version 80 onwards). Earlier this month I was invited to give
CSS が行う作業の量について考えたことはありますか？1 つの属性を変更すると、ウェブサイト全体が突然別のレイアウトで表示される。魔法のようなものです。これまで、ウェブ デベロッパーのコミュニティは、その魔法を目撃し、観察することしかできませんでした。独自の魔法を作りたい場合はどうすればよいですか？マジシャンになりたい場合はどうすればよいですか？ Houdini を導入しましょう。 Houdini タスクフォースは、Mozilla、Apple、Opera、Microsoft、HP、Intel、Google のエンジニアで構成されており、CSS エンジンの特定の部分をウェブ デベロッパーに公開するために協力しています。タスクフォースは、W3C に承認され、実際のウェブ標準となることを目標に、ドラフトのコレクションに取り組んでいます。いくつかの大まかな目標を設定し、それを仕様案に変え、さらに、
The way we write CSS is about to change. No, I don’t mean you have to change how you write your styles, but we as developers are about to get a lot more control. What am I talking about? That would be the CSS Houdini spec and the new browser APIs that are coming out as a part of it. Houdini 101 So what is Houdini? Well, I’m glad you asked. Houdini gives developers access to the CSS object model (C
It has always been possible to create stylesheets using JavaScript. However, the process has historically been to create a <style> element using document.createElement('style'), and then access its sheet property to obtain a reference to the underlying CSSStyleSheet instance. This method can produce duplicate CSS code and its attendant bloat, and the act of attaching leads to a flash of unstyled c
Get affordable and hassle-free WordPress hosting plans with Cloudways, now offering 40% off for 4 months, and 40 free migrations. Major performance gains are to be had from browser caching CSS. You ensure your server is set up to send headers that tell the browser to hang onto the CSS file for a given amount of time. It’s a best-practice that many if not most sites are doing already.

Jan 2023 - There have been additional updates to how Safari exposes list semantics based on their nesting context. For instance, if a list is a descendant of a <nav> element, then even if the list styles are removed, Safari/VoiceOver will expose this as a list to users. Keep in mind the way that Safari/VoiceOver behave is not due to a bug, but rather a response to developer overuse of lists which
