Can you get valid CSS property values from the browser?


I had someone write in with this very legit question. Lea just blogged about how you can get valid CSS properties themselves from the browser. That’s like this. CodePen Embed Fallback That gives you, for example, the fact that cursor is a thing. But then how do you know what valid values...

What Happens When Border Radii Overlap?


I’d wager that most times we’re rounding box corners in CSS, we’re applying a uniform border-radius value across the border. It’s a nice touch of polish in many designs. But there are times when we might want different radii for different corners. Easy, right? That way the property takes four...

What does 100% mean in CSS?


When using percentage values in CSS like this… .element { margin-top: 40%; } …what does that % value mean here? What is it a percentage of? There’ve been so many times when I’ll be using percentages and something weird happens. I typically shrug, change the value to something else...

Computed Values: More Than Meets the Eye


Browser DevTools are indispensable for us front end developers. In this article, we’ll take a look at the Computed tab, a small corner of the DevTools panel that shows us big things, like how relative CSS values are resolved. We’ll also see how inheritance fits into the browser’s...

Making lil’ me


Cassie Evans made a lovely illustration of herself and then used Greensock to add a flourish of animations to polish it off. Cassie wrote a series of posts about how she did it: In this post we’ll cover how to get values from the mouse movement and plug them into an animation. This is...

`lh` and `rlh` units


There’s some new units I was totally unaware of from the Level 4 spec for CSS values! The lh unit is “equal to the computed value of line-height” and rlh is the same only of the root element (probably the <html> element) rather than the current element. Why would that...

@property


The @property is totally new to me, but I see it’s headed to Chrome, so I suppose it’s good to know about! There is a draft spec and an “intent to ship” document. The code from that document shows: @property --my-property { syntax: "<color"; initial-value: green; ...

Create a Responsive CSS Motion Path? Sure We Can!


There was a discussion recently on the Animation at Work Slack: how could you make a CSS motion path responsive? What techniques would be work? This got me thinking.

Adventures in CSS Semi-Transparency Land


Recently, I was asked to make some tweaks to a landing page and, among the things I found in the code, there were two semitransparent overlays — both with the same RGB values for the background-color — on top of an image. Something like this: <img src='myImage.jpg'/> <div...

Understanding Immutability in JavaScript


If you haven’t worked with immutability in JavaScript before, you might find it easy to confuse it with assigning a variable to a new value, or reassignment. While it’s possible to reassign variables and values declared using let or var, you'll begin to run into issues when you try that with...

Resizing Values in Steps in CSS


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...
