Clamp.js is a small vanilla JavaScript library that truncates HTML element content with an ellipsis when it exceeds a specified number of lines or height. It works cross-browser, optionally leveraging the native -webkit-line-clamp where available.

Use cases

• truncate long text to a fixed number of lines with an ellipsis
• clamp dynamic content to a fixed pixel height
• add a read more link at the end of truncated text
• cross-browser line clamping without experimental CSS
• auto-clamp content to fit available container space

When to choose

• you need multi-line text truncation in older browsers lacking CSS line-clamp support
• you want a dependency-free vanilla JS solution
• you need custom truncation characters or trailing HTML like a read-more link

When to avoid

• your target browsers support the modern CSS line-clamp property
• the project needs an actively maintained library
• you use a framework with built-in truncation utilities
