FAQ
Answered from alert's own facts: its shelf, the weights it was drawn in, its siblings and its dates.
- What is the alert icon for?
- Warnings, failed validation and the confirm step in front of something destructive. It is filed under Actions in Keyline Icons, drawn on the same 24×24 grid as the rest of the set. People look for it as exclamation, warning, caution, attention, important and error, and the browser's search matches all of those.
- What styles does the alert icon come in?
- Stroke. There are no duotone or fill drawings of this one: a filled weight needs an enclosed area, either in the glyph itself or from a square or circle container.
- Is there a square or circle version of alert?
- Yes. The same drawing is also boxed, as square-alert and circle-alert. Each is its own icon with its own name.
- What other icons go with alert?
- ban, check, circle-check, circle-minus, circle-more-horizontal and circle-more-vertical, and 12 more, all shown below. They are the Actions shelf: nothing else in the set is named after alert.
- How do I import alert in React?
- <Alert /> is the component, and the weight decides the module: stroke from "@keyline-icons/react". It takes the usual SVG props plus a size, so <Alert size={16} /> and className="size-4" both work, and there is no provider or theme to set up.
- Where is the alert SVG?
- icons/stroke/alert.svg in the repository, normalised: no wrapper, no ids and no classes to strip out. The tabs above hand you the same drawing as SVG or JSX without the download, and neither needs an install.
- When was alert added to the set?
- Added 23 Aug 2026. It ships in v0.1.1, so an install at that version or later has it.
Questions about the set rather than about this drawing are answered where they belong. The home page covers what the set is, how the three styles differ, why some icons come boxed and where the Figma file is; installing the set in a shadcn/ui project covers the React package, the CLI and using an icon without React. The MIT licence is stated in the footer of every page.
