-webkit-line-clamp

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The -webkit-line-clamp CSS property allows limiting of the contents of a block to the specified number of lines.

It only works in combination with the display property set to -webkit-box or -webkit-inline-box and the -webkit-box-orient property set to vertical. Despite them being deprecated, the co-dependency of these three properties is fully specified behavior and will continue to be supported.

In most cases you will also want to set overflow to hidden, otherwise the contents won't be clipped but an ellipsis will still be shown after the specified number of lines.

When applied to anchor elements, the truncating can happen in the middle of the text, not necessarily at the end.

Note: This property was originally implemented in WebKit and has some issues, such as the dependency on two other legacy properties. It got standardized in CSS Overflow Module Level 4 for legacy support. CSS Overflow Module Level 4 also defines a line-clamp property, which is meant to replace this property and avoid its issues. However, all browsers that support line-clamp will also support -webkit-line-clamp for compatibility reasons.
