Component Skill — components/announcement/component-skill.md

Native basis

A non-modal <dialog open> labelled by its message, an inner wrapper with an icon, the message and a link, and a <form method="dialog"> close button that dismisses it without script.

Web Platform APIs

<dialog>:has()Container queries

Classes

.mk-announcement.mk-announcement-inner.mk-announcement-close.mk-announcement-tag

Data attributes

data-variant: primary, inline, floating.

§Bar

Default: a muted bar - a non-modal <dialog open>; the close button sits in a <form method="dialog"> and dismisses it without script. Try it.

§Primary

data-variant='primary': a strip in the primary color - for the one thing everyone must see.

§Inline

data-variant='inline': a rounded card inside the content - an icon in the chart color, the message, a link.

§Floating

data-variant='floating': fixed to the bottom of the viewport and sliding in (@starting-style) - here inside a positioned frame. Dismiss it to see the page behind.
