Google Fonts is Adding font-display

Google announced at I/O that their font service will now support the font-display property which resolves a number of web performance issues. If you're hearing cries of joy, that's probably Chris as he punches the air in celebration. … Read article The post Google Fonts is Adding...

SVG Properties and CSS

13.5.2019
There are many Scalable Vector Graphics (SVG), but only certain attributes can be applied as CSS to SVG. Presentation attributes are used to style SVG elements and can be used as CSS properties. Some of these attributes are SVG-only while others are already shared in CSS, such as font-size...

Get a CSS Custom Property Value with JavaScript

11.4.2019
Here’s a neat trick from Andy Bell where he uses CSS Custom Properties to check if a particular CSS feature is supported by using JavaScript. Basically, he's using the ability CSS has to check for browser support on a particular property, setting a custom property that returns a value of either...

Using a Mixin to Take the Math out of Responsive Font Sizes

9.4.2019
Responsive Font Size (RFS) is an engine that automatically calculates and updates the font-size property on elements based on the dimensions of the browser viewport. If you’re thinking that sounds familiar, that’s because there is a slew of tools out there that offer various approaches for fluid...

JavaScript Glossary: String length

26.3.2019
Basics The length property of the String object returns the number of code points in a string object. It indicates the length of the string

Mask Compositing: The Crash Course

2.3.2019
At the start of 2018, as I was starting to go a bit deeper into CSS gradient masking in order to create interesting visuals one would think are impossible otherwise with just a single element and a tiny bit of CSS, I learned about a property that had previously been completely unknown to...

Control Icons with Font Size

27.2.2019
Here’s a nifty trick from Andy Bell that now seems a little obvious in hindsight: if you set an SVG to have a width and height of 1em then you can change the size of it with the font-size property. Try and change the font-size on the body element below to see the icon scale with the text: ...

How @supports Works

18.2.2019
CSS has a neat feature that allows us to test if the browser supports a particular property or property:value combination before applying a block of styles — like how a @media query matches when, say, the width of the browser window is narrower than some specified size and then the CSS within...

​​Avoiding those dang cannot read property of undefined errors

13.2.2019
​​​​Uncaught TypeError: Cannot read property 'foo' of undefined.​ The dreaded error we all hit at some point in JavaScript development. Could be an empty state from an API that returns differently than you expected. Could be something else. We don’t know because the error itself is so general...

Well, Typetura seems fun

1.2.2019
I came across this update from Scott Kellum's and Sal Hernandez's project Typetura via my Medium feed this morning, and what a delight?! (Also, wow, I really have been out of the game for a minute.) Typetura.js is a fluid design solution, for any property, based on any input. It’s not for just...

Slide an Image to Reveal Text with CSS Animations

29.1.2019
I want to take a closer look at the CSS animation property and walk through an effect that I used on my own portfolio website: making text appear from behind a moving object. Here’s an isolated example if you’d like to see the final product. Here’s what we're going to work with: See the...

Nested Destructuring

25.12.2018
Destructuring in JavaScript can initially feel confusing but the truth is that destructuring can make your code a bit more logical and straight forward. Destructuring does look a bit more complex when you’re looking for a property several objects deep, so let’s have a look at how to...

An Initial Implementation of clip-path: path();

24.12.2018
One thing that has long surprised (and saddened) me is that the clip-path property, as awesome as it is, only takes a few values. The circle() and ellipse() functions are nice, but hiding overflows and rounding with border-radius generally helps there already. Perhaps the most useful value...

Fighting FOIT and FOUT Together

19.12.2018
Lots from Divya with the setup: There are 2 kinds of problems that can arise when using webfonts; Flash of invisible text (FOIT) and Flash of Unstyled Text (FOUT) ... If we were to compare them, FOUT is of course the lesser of the two evils If you wanna fight FOIT, the easiest tool is...

A CSS Venn Diagram

17.12.2018
This is pretty wild: Adrian Roselli has made a series of rather complex Venn diagrams using nothing but CSS. With a combination of the Firefox dev inspector, plus a mixture of CSS Grid and the shape-outside property, it’s possible to do this and without a ton of hacks, too. I also think it’s super...

Reversing an Easing Curve

17.12.2018
Let’s take a look at a carousel I worked on where items slide in and out of view with CSS animations. To get each item to slide in and out of view nicely I used a cubic-bezier for the animation-timing-function property, instead of using a standard easing keyword. See the Pen Carousel with reversed...

The div that looks different in every browser

13.7.2018
It's not that Martijn Cuppens used User Agent sniffing, CSS hacks, or anything like that to make this quirk div. This is just a plain ol' <div> using the outline property a la: div { inset 100px green; outline-offset: -125px; } It looks different in different browsers because browsers...
