Using Heroicons with TailwindCSS

Heroicons are SVG-based icons packaged by the creators of TailwindCSS. They come in two size variants, 20, which is suitable for small buttons and form elements, and a 24 size, that is useful for primary navigation buttons like call to action and hero sections. 24 size comes as solid and outline.

A Heroicon is a React component that returns an <svg> element with props passed to it. We are able to set values for the properties of the <svg> element, such as className, stroke, and fill, by passing them to the Heroicon component.

The CSS contain property

The purpose of CSS’ contain property (“CSS containment”) is twofold:

1. Optimization
2. Styling possibilities

When we apply contain to an element we’re isolating it (and it’s descendents) from the rest of the page, and this isolation what opens those possibilities. There are different types of containment which all do different things, and we’ll be getting into each of them.

RTL Styling 101

A couple of weeks ago I was super excited about publishing my first CSS-Tricks post: “Letter Spacing is Broken. Forget about that though, what’s important is the post’s topic: letter spacing is broken and doesn’t work as the CSS Specification says it should. In a nutshell, instead of spacing the characters evenly, it leaves an unpleasant space at the end of the element.

While this inconsistency between the web and the spec is just a quirk for a Spanish/English speaker like me, for speakers of right-to-left (RTL) languages like Arabic or Hebrew, an annoying space is left at the start or end of a word. Firefox (Gecko) kinda fixes it and rearranges the unnecessary space at the end (in the reading order), but Google and Safari (Blink and Webkit) leave it at the start.

JavaScript in particular has quite a few different types of loops. I haven’t even used all of them, so for my own curiosity, I thought I’d do a high-level overview of them. And as it turns out, there are pretty good reasons I haven’t used at least a couple of the different types.
