Frequently asked questions
What the Alert Square icon means and where it's used, then how to install, style, label and license it.
The alert-square icon represents a warning or error notification in a square shape. It is commonly used to alert users of potential issues or errors.
In software applications, this icon is often used in conjunction with error messages or alerts to draw the user's attention.
From a UX perspective, the square shape of the icon helps to convey a sense of stability or reliability.
Alert Square is one of 1,093 icons in Material Line Icons, made by Vjacheslav Trushkin 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 AlertSquareIcon to components/icons/line-md-alert-square.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 AlertSquareIcon 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 Square icon, or any of 1,093 Material Line 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 Square 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 Square", so screen readers say what it does.
Yes. AlertSquareIcon passes every SVG prop to the svg element, so <AlertSquareIcon 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 Material Line Icons, Vjacheslav Trushkin and the license.
Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
