Font Icons
Search and preview Material Symbols icons, then copy the CSS class, HTML markup, or code point for your project. Material Symbols supports variable fill, weight, grade, and optical-size axes for flexible interface icon styling. Font icons behave like text: CSS can control their size, color, alignment, and interaction states without editing an image file. A consistent icon family also helps users recognize repeated actions more quickly across navigation, forms, and controls. Use visible text or an accessible label whenever an icon communicates an action. For performance, load only the library and styles your interface needs. Confirm licensing and usage requirements with the library publisher before distributing a finished product.

Add Material Symbols to your website or app

Add the library once, copy an icon from the results above, and include an accessible label when the icon communicates meaning.

1. Load the icon library

<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Material+Symbols+Outlined">

Reference version: Google Fonts variable icon font

2. Copy an icon

Use Copy class when you already have markup, or Copy HTML for a ready-to-paste element.

Code points are useful for CSS generated content and tools that work directly with icon fonts.

3. Keep icons accessible

Hide decorative icons from assistive technology. When an icon communicates meaning, pair it with visible text or an accessible label.

Confirm licensing and usage requirements with the library publisher before distributing a finished product.

Practical Notes

Icon Implementation Checklist

Icons work best when they support quick recognition without becoming the only way a user understands an action.

Label important controls

Use visible text or accessible labels for buttons where the icon meaning may be ambiguous.

Keep style consistent

Mixing filled, outlined, sharp, and rounded icon families can make an interface feel uneven.

Load only what you need

Large icon fonts can cost performance. SVG sprites or subset fonts are better for focused interfaces.
