Animations, theming, components, and more layout patterns are live and ready to help kick start or inspire your UI and UX.
I'm excited to share many new web.dev patterns! These additions are from the show GUI Challenges where I share my strategies on how to build various components and common interface needs, then collect user submissions for the same tasks and help us all grow our perspectives on how to solve them.
Turns out GUI Challenges fit nicely into patterns:
<h1 split-by="word" word-animation="hover">
hover the words
</h1>
@media (prefers-reduced-motion:no-preference) {
[word-animation] {
display: inline-flex;
flex-wrap: wrap;
gap: 1ch
}
}
@media (prefers-reduced-motion:no-preference) and (hover) {
[word-animation=hover] {
overflow: hidden;
overflow: clip
}
[word-animation=hover]>span {
transition: transform .3s ease;
cursor: pointer
}
[word-animation=hover]>span:not(:hover) {
transform: translateY(50%)
}
}
const span = (text, index) => {
const node = document.createElement('span')
node.textContent = text
node.style.setProperty('--index', index)
return node
}
export const byWord = text =>
text.split(' ').map(span)
const {matches:motionOK} = window.matchMedia(
'(prefers-reduced-motion: no-preference)'
)
if (motionOK) {
const splitTargets = document.querySelectorAll('[split-by]')
splitTargets.forEach(node => {
let nodes = byWord(node.innerText)
if (nodes)
node.firstChild.replaceWith(...nodes)
})
}
Now they can be embedded into posts (like above), aggregated for easy browsing and inspiration, and also have added new categories for other contributors to add their patterns to. Take a look around, take some code: it's all there for you.
Overview
Three new pattern categories:
Plus, five new patterns added to the existing Layout patterns.

Theming
View the theming patterns landing page or check each out individually:
One pattern is for building a client side theme switch so users can indicate their preference without it being directly tied to their system preference. The other is for creating a theming design system with CSS custom properties.
Here's a preview of the color schemes pattern:

New layout patterns on centering
View the layout patterns landing page or check each out individually:
Each demo features a grab handle to resize the container and a button to add a child to the layout. These, as explained in the article, are to help you feel the strengths and weaknesses of various centering techniques the web offers. Plus, they have fun names.
Here is the article determined "winner" of the centering exploration, the Gentle Flex:
<article class="gentle-flex">
<h1>Gentle Flex</h1>
</article>
.gentle-flex {
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
gap: 1ch;
}
Wrap up
I hope these new patterns help teach you new techniques, inspire you, provide insights into accessibility and overall keep you hyped on building UI. Stay tuned for more patterns as the Chrome Team continues adding to these collections.
