CSS Algorithms
6.3.2019
I wouldn't say the term "CSS algorithm" has widespread usage yet, but I think Lara Schenck might be onto something. She defines it as:
a well-defined declaration or set of declarations that produces a specific styling output
So a CSS algorithm isn't really a component where there is some parent...
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...
Using React Portals to Render Children Outside the DOM Hierarchy
15.1.2019
Say we need to render a child element into a React application. Easy right? That child is mounted to the nearest DOM element and rendered inside of it as a result.

);
}

I had never heard of the backdrop-filter property until yesterday, but after a couple of hours messing around with it I’m positive that it’s nothing more than magic. This is because it adds filters (like changing the hue, contrast or blur) of the background of an element without changing the text...

CSS preprocessor variables and CSS custom properties (often referred to as "CSS variables") can do some of the same things, but are not the same.

Say you have a really long word within some text inside an element that isn't wide enough to hold it. A common cause of that is a long URL finding it's way into copy. What happens? It depends on the CSS. How that CSS is controlling the layout and what the CSS is telling the text to do.
