If the text is longer than one line, it will be truncated and end with an ellipsis .

  • overflow: hidden prevents the text from overflowing its dimensions (for a block, 100% width and auto height).
  • white-space: nowrap prevents the text from exceeding one line in height.
  • text-overflow: ellipsis makes it so that if the text exceeds its dimensions, it will end with an ellipsis.
  • width: 200px; ensures the element has a dimension, to know when to get ellipsis
  • Only works for single line elements.
