Truncate text multiline

CSS, Layout, Intermediate

If the text is longer than one line, it will be truncated for n lines and end with an gradient fade.

overflow: hidden prevents the text from overflowing its dimensions (for a block, 100% width and auto height).
width: 400px ensures the element has a dimension.
height: 109.2px calculated value for height, it equals font-size * line-height * numberOfLines (in this case 26 * 1.4 * 3 = 109.2).
height: 36.4px calculated value for gradient container, it equals font-size * line-height (in this case 26 * 1.4 = 36.4).
background: linear-gradient(to right, rgba(0, 0, 0, 0), #f5f6f9 50%) gradient from transparent to #f5f6f9.
