Text truncation, using CSS

Text truncation is a tool that many designs make use of to prevent text from overflowing its container. It can be applied both to single line and multiline text, and it is a great way to ensure that the text fits within the design constraints.

See the embedded CodePen

Truncate single line text

Single line text can be easily truncated using a couple of CSS fundamentals. First off, you'll need to use white-space: nowrap to prevent the text from wrapping to the next line. Then, you can use overflow: hidden to hide any overflow, and text-overflow: ellipsis to add an ellipsis at the end of the text.

💬 Note

For this technique to work, a fixed width must be set on the element or its parent.

.truncate-text {
  overflow: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
}

Truncate multi line text

For multi-line text, you'll still need to use overflow: hidden to prevent the text from overflowing its container. However, you can't use text-overflow: ellipsis to add an ellipsis at the end of the text.

Instead, you can use the -webkit-line-clamp property to limit the number of lines displayed. This property accepts an integer value that specifies the maximum number of lines to be displayed. You'll also need to use display: -webkit-box and -webkit-box-orient: vertical to ensure that -webkit-line-clamp is applied correctly.

💬 Note

At the time of writing, -webkit-line-clamp is still a working draft, but is supported across most modern browsers. Always check the current browser support beforehand.

.truncate-text-multiline {
  display: -webkit-box;
  -webkit-line-clamp: 3;
  -webkit-box-orient: vertical;
  overflow: hidden;
}
