-webkit-line-clamp

The -webkit-line-clamp CSS property allows limiting of the contents of a block container 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.

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.

/* Keyword value */
-webkit-line-clamp: none;

/* <integer> values */
-webkit-line-clamp: 3;
-webkit-line-clamp: 10;

/* Global values */
-webkit-line-clamp: inherit;
-webkit-line-clamp: initial;
-webkit-line-clamp: unset;

none

This value specifies that the content won't be clamped.

<integer>

This value specifies the number of lines after which the content will be clamped. It must be greater than 0.

none | <integer>

HTML

<p>
  In this example the <code>-webkit-line-clamp</code> property is set to <code>3</code>, which means the text is clamped after three lines.
  An ellipsis will be shown at the point where the text is clamped.
</p>

CSS

p {
  width: 300px;
  display: -webkit-box;
  -webkit-box-orient: vertical;
  -webkit-line-clamp: 3;
  overflow: hidden;
}
