The Power (and Fun) of Scope with CSS Custom Properties


You’re probably already at least a little familiar with CSS variables. If not, here’s a two-second overview: they are really called custom properties, you set them in declaration blocks like --size: 1em and use them as values like font-size: var(--size);, they differ from preprocessor variables...

Highlights from Chrome Dev Summit 2019


Ire Aderinokun has made another round-up summary of some things that piqued her attention during this year’s Chrome Dev Summit and there’s a lot of exciting news! There’s the :is selector (which Geoff wrote about a while back) as well as logical properties, updates to standard form elements,...

An Early Look at the Vue 3 Composition API in the Wild


I recently had an opportunity to try the new Vue Composition API in a real project to check where it might be useful and how we could use it in the future. Until now, when we were creating a new component we were using Options API. That API forced us to separate the component’s code by options...

Pac-Man… in CSS!


You all know famous Pac-Man video game, right? The game is fun and building an animated Pac-Man character in HTML and CSS is just as fun! I’ll show you how to create one while leveraging the powers of the clip-path property. See the Pen Animated Pac-Man by Maks Akymenko (@maximakymenko) ...

Two-Value Display Syntax (and Sometimes Three)


You know the single-value syntax: .thing { display: block; }. The value "block" being a single value. There are lots of single values for display. For example, inline-flex, which is like flex in that it becomse a flex container, but behaves like an inline-level element rather than a block-level...

Show Search Button when Search Field is Non-Empty


I think the :placeholder-shown selector is tremendously cool. It allows you to select the placeholder of an input (<input placeholder="...">) when that placeholder is present. Meaning, the input does not yet have any value. You might think input[value] could do that, or help match on...

Bidirectional Horizontal Rules in CSS


Say you have a <blockquote> and the design calls for a thick border along the left side. Well, you might not necessarily mean left side, but actually mean on the side of the start of the text. That's exactly what CSS logical properties are meant to address, and Hussein Al Hammad has a nice...

Patterns for Practical CSS Custom Properties Use


I've been playing around with CSS Custom Properties to discover their power since browser support is finally at a place where we can use them in our production code. I’ve been using them in a number different ways and I’d love for you to get as excited about them as I am. They are so useful...

Jaké novinky přinese PHP 7.4


Vydání PHP 7.4 je plánováno na 28. listopadu 2019. Přináší hromadu zajímavých věcí - Typed Properties, Array Functions, Preload, FFI a pár dalších vylepšení. Sice přibyly i nějaké deprecations, ale typicky se týkají podivného chování, takže upgrade by měl být snadný

designMode


Every once in a while I stumble upon an API or browser setting that I can’t believe ever existed. Such examples can be seen in the numerous String.prototype properties such as bold, italics, and even blink, which wrap given string text in their representative HTML tags. Bizarre. It...

Overflow And Data Loss In CSS


"Data Loss" is a funny term. My brain thinks of like packet loss on the way from the server to your browser, resulting in missing content in files. Perhaps it is that on some level, but in CSS parlance, it has to do with the overflow property. Too much content for sized container + hidden overflow...

Using Custom Properties to Wrangle Variations in Keyframe Animations


Have you ever wondered how to customize CSS animations keyframes without using any preprocessor feature, like mixins? I keep reaching for preprocessors for this reason, but it would so nice to drop yet one more dependency and go with vanilla CSS. Well, I found a way to account for variations within...

Logical Operations with CSS Variables


Very often, while using switch variables (a variable that's either 0 or 1, a concept that's explained in a greater detail in in this post), I wish I could perform logical operations on them. We don't have functions like not(var(--i)) or and(var(--i), var(--k)) in CSS, but we can emulate these...

Multiline truncated text with “show more” button


Now that we've got cross-browser support for the line-clamp property, I expect we'll see a lot more of that around the web. And as we start to see it more in use, it’s worth the reminder that: Truncation is not a content strategy. We should at least offer a way to read that that truncated content...

Nested Gradients with background-clip


I can't say I use background-clip all that often. I'd wager it's hardly ever used in day-to-day CSS work. But I was reminded of it in a post by Stefan Judis, which consistently was itself a learning-response post to a post over here by Ana Tudor. Here's a quick explanation. You've probably seen...

Can you rotate the cursor in CSS?


Kinda! There is no simple or standard way to do it, but it's possible. You can change the cursor to different built-in native versions with CSS with the cursor property, but that doesn't help much here. You can also use that property to set a static image as the cursor. But again that doesn't help...

Staggered CSS Transitions


Let's say you wanted to move an element on :hover for a fun visual effect. @media (hover: hover) { .list--item { transition: 0.1s; transform: translateY(10px); } .list--item:hover, .list--item:focus { transform: translateY(0); } } Cool cool. But what if you had several list...

Contextual Utility Classes for Color with Custom Properties


In CSS, we have the ability to access currentColor which is tremendously useful. Sadly, we do not have access to anything like currentBackgroundColor, and the color-mod() function is still a ways away. With that said, I am sure I am not alone when I say I'd like to style some links based on...
