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.
