• 6 CSS snippets every front-end developer should know in 2023

At Container Query

@container is a new css selector

.panel {
	container: layers-panel / inline-size;
}

.card {
	padding: 1rem;
}

@container layers-panel (min-width: 20rem) {
	.card {
		padding: 2rem;
	}
}

Scroll Snap

Well orchestrated scroll experiences set your experience apart from the rest, and scroll snap  is the perfect way to match system scroll UX while providing meaningful stopping points.

.snaps {
	overflow-x: scroll;
	scroll-snap-type: x mandatory;
	overscroll-behavior-x: contain;
}

.snap-target {
	scroll-snap-align: center;
}

.snap-force-stop {
	scroll-snap-stop: always;
}

Grid Pile

Grid Pile

.pile {
	display: grid;
	place-content: center;
}

.pile > * {
	grid-area: 1/1;
}

Easy Circle

.circle {
	inline-size: 25ch;
	aspect-ratio: 1;
	border-radius: 50%;
}

Control variants with @layer

You probably have seen this if you are using TailwindCSS

/* file buttons.css */
@layer components.buttons {
  .btn.primary {
    …
  }
}

Memorize less and reach more with logical properties

Memorize this one new box model and never have to worry about changing left and right padding or margin for international writing modes and document directions again. Adjust your styles from physical properties to logical ones like padding-inline, margin-inline, inset-inline, and now the browser will do the adjusting work.

button {
	padding-inline: 2ch;
	padding-block: 1ch;
}

article > p {
	text-align: start;
	margin-block: 2ch;
}

.something::before {
	inset-inline: auto 0;
}
