Examples
Cap a fluid element
Use max-w:* to let an element shrink with its container while preventing it from growing too wide.
<main class="w:full max-w:5xl mx:auto"> ...</main>Generated CSS
@layer theme { :root { --container-5xl: 64rem }}@layer utilities { .mx\:auto { margin-inline: auto } .max-w\:5xl { max-width: var(--container-5xl) } .w\:full { width: 100% }}Set a readable measure
Use text-relative units when the maximum width is based on reading comfort instead of the container scale.
<article class="w:full max-w:72ch"> ...</article>Keep media responsive
Use max-w:full to prevent replaced elements such as images or videos from overflowing their parent.
<img class="h:auto max-w:full" src="..." alt="" />Use viewport and container caps
Use max-vw when an element should never exceed the viewport width. Use max-w:* when the cap should follow the container theme token scale.
<section class="max-vw max-w:7xl@lg"> ...</section>Apply conditionally
Apply styles based on different states using selectors and conditional queries.
<div class="max-w:full max-w:72ch@print max-w:4xl@sm">...</div>Pair max-w:* with w:full for wrappers that should be fluid until they hit the cap.
