Alert Triangle

The alert-triangle icon represents a warning or error notification, often used to alert users to potential issues or problems. It originates from the need to visually communicate critical information to users in a clear and concise manner. The alert-triangle icon's significance lies in its ability to grab the user's attention and convey a sense of urgency or importance.

In software and web development, the alert-triangle icon is commonly used in user interfaces to notify users of errors, warnings, or other critical information. For example, it appears in platforms like GitHub, where users receive notifications about errors or warnings in their code. Additionally, popular applications like Slack and Trello utilize the alert-triangle icon to alert users to important updates or notifications.

From a UX perspective, the alert-triangle icon communicates to users that they need to take action or pay attention to a specific issue. It helps to manage user expectations and provides a sense of control over the interface. When used effectively, the alert-triangle icon can reduce user frustration and anxiety, making the overall experience more enjoyable and engaging.

Alert Triangle is one of 286 icons in Feather Icons, made by Cole Bemis and released under MIT. It is drawn on a 24 × 24 grid with a 2 stroke.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds AlertTriangleIcon to components/icons/feather-alert-triangle.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed AlertTriangleIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Alert Triangle icon, or any of 286 Feather Icons icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation, and its stroke.

Alert Triangle is a line icon drawn with a stroke width of 2. Change it in Customize before you copy, or pass strokeWidth to the installed component when all of its strokes share one width.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Alert Triangle", so screen readers say what it does.

Yes. AlertTriangleIcon passes every SVG prop to the svg element, so <AlertTriangleIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes. MIT allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.

No visible credit is required: MIT only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Feather Icons, Cole Bemis and the license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
