4 CSS Grid Properties (and One Value) for Most of Your Layout Needs
30.3.2020
CSS Grid provides us with a powerful layout system for websites. The CSS-Tricks guide gives you a comprehensive overview of Grid’s properties with layout examples. What we’re going to do here is a reverse approach to show you the smallest possible set of grid properties you need to know to meet...
How to use CSS Scroll Snap
27.3.2020
Nada Rifki demonstrates the scroll-snap-type and scroll-snap-alignCSS properties. I like that the demo shows that the items in the scrolling container can be different sizes. It is the edges of those children that matter, not some fixed snapping distance.
I like Max Kohler's coverage...
Did You Know the Ordered List Element Has Start and Reversed Attributes?
24.3.2020
I sure didn't! Tomek Sułkowsi shows how we can reverse the numbering of ordered lists with a simple HTML attribute:
<ol reversed<liApple</li<liBanana</li<liPear</li</ol
CodePen Embed Fallback
And the start attribute can be added to begin the list at a number other...
Flexbox and absolute positioning
18.3.2020
Chen Hui Jing notes that when you absolutely position a flex item, it's no longer part of the flex layout. Except... it kinda is a little bit. If you make the child position: absolute; but don't apply any top/right/bottom/left properties, then flexbox alignment will still apply to it.
It's odd...
A Complete Guide to calc() in CSS
17.3.2020
CSS has a special calc() function for doing basic math. Here's an example:
.main-content {
/* Subtract 80px from 100vh */
height: calc(100vh - 80px);
}
In this guide, let's cover just about everything there is to know about this very useful function.
calc() is for values
The only place you...
How to Make a Line Chart With CSS
11.3.2020
Line,  bar, and pie charts are the bread and butter of dashboards and are the basic components of any data visualization toolkit. Sure, you can use SVG or a JavaScript chart library like Chart.js or a complex tool like D3 to create those charts, but what if you don't want to load yet another...
Negative Margins
9.3.2020
PPK digs into the subject, which he found woefully undercovered in web tech documentation. Our entry doesn't mention them at all, which I'll aim to fix.
Agree on this situation:
This is by far the most common use case for negative margins. You give a container a padding so that its contents have...
Helping Browsers Optimize With The CSS Contain Property
10.2.2020
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....
Custom Styling Form Inputs With Modern CSS Features
7.2.2020
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.
Here’s...
Get Moving (or not) with CSS Motion Path
3.2.2020
We just linked up the idea that offset-path can be cleverly used to set type on a path. Don't miss Michelle Barker's experimentation either, with drawing paths or animating text along a path.
Dan Wilson has also been following this tech for quite a while and points out why the sudden surge...
Resizing Values in Steps in CSS
30.1.2020
There actually is a steps() function in CSS, but it's only used for animation. You can't, for example, tell an element it's allowed to grow in height but only in steps of 10px. Maybe someday? I dunno. There would have to be some pretty clear use cases that something like background-repeat: space...
Set Type on a Circle… with offset-path
28.1.2020
Here's some legit CSS trickery from yuanchuan. There is this CSS property offset-path. Once upon a time, it was called motion-path and then it was renamed. I sort of rolled my eyes at the time, because the property is so obviously for animating things along a path. But you don't have to use it...
Min and Max Width/Height in CSS
24.1.2020
Here's a nice deep dive into min-width / min-height / max-width / max-height from Ahmad Shadeed. I like how Ahmad applies the properties to real-world design situations in addition to explaining how it works. In the very first demo, for example, he shows a button where min-width is used as a method...
Building Multi-Directional Layouts
23.1.2020
There are some new features in CSS that can assist us with building layouts for different directions and languages with ease. This article is about CSS logical properties and values (e.g. margin-inline-start).  These are a W3C working draft that still going under heavy editing, but have...
The Web in 2020: Extensibility and Interoperability
22.1.2020
In the past few years, we’ve seen a lot of change and diversion in regard to web technologies. In 2020, I foresee us as a web community heading toward two major trends/goals: extensibility and interoperability. Let’s break those down.
Extensibility
Extensibility describes...
Thinking Through Styling Options for Web Components
16.1.2020
Where do you put styles in web components?
I'm assuming that we're using the Shadow DOM here as, to me, that's one of the big draws of a web component: a platform thing that is a uniquely powerful thing the platform can do. So this is about defining styles for a web component in a don't-leak-out...
How many CSS properties are there?
15.1.2020
Tomasz Łakomy posted a joke tweet about naming all the CSS attributes and Tejas Kumar replied with a joke answer, going as far as making an npm module. You can even run a terminal command to see them:
npx get-all-css-properties
You'll get 259 of them. The source code uses the website quackit.com...
Re-creating the ‘His Dark Materials’ Logo in CSS
11.1.2020
The text logo has a slash cut through the text. You set two copies on top of one another, cropping both of them with the clip-path property.
What's interesting to me is how many cool design effects require multiple copies of an element to do something cool. To get the extra copy, at least with...
Multi-Thumb Sliders: General Case
8.1.2020
The first part of this two-part series detailed how we can get a two-thumb slider. Now we'll look at a general multi-thumb case, but with a different and better technique for creating the fills in between the thumbs. And finally, we'll dive into the how behind the styling a realistic 3D-looking...
Multi-Thumb Sliders: Particular Two-Thumb Case
7.1.2020
This is a concept I first came across a few years back when Lea Verou wrote an article on it. Multi-range sliders have sadly been removed from the spec since, but something else that has happened in the meanwhile is that CSS got better — and so have I, so I recently decided to make my...
