title: Truncate multiline text
|
|
tags: layout,intermediate

|
|
|
Truncates text that is longer than one line.
|
|
|
|
- Use `overflow: hidden` to prevent the text from overflowing its dimensions.
|
|
- Set a fixed `width` to ensure the element has at least one constant dimension.
|
|
- Set `height: 109.2px` as calculated from the `font-size`, using the formula `font-size * line-height * numberOfLines` (in this case `26 * 1.4 * 3 = 109.2`).
|
|
- Set `height: 36.4px` as calculated for the gradient container, based on the formula `font-size * line-height` (in this case `26 * 1.4 = 36.4`).
|
|
- Use `background` with `linear-gradient()` to create a gradient from `transparent` to the `background-color`.
