title: Truncate text multiline
|
|
tags: layout
|
|
---
|
|
|
|
If the text is longer than one line, it will be truncated for `n` lines and end with an gradient fade.
|
|
|
|
```html
|
|
<p class="truncate-text-multiline">
|
|
Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut
|
|
labore et.
|
|
</p>
|
|
```
|
|
|
|
```css
|
|
.truncate-text-multiline {
|
|
overflow: hidden;
|
|
display: block;
|
|
height: 109.2px;
|
|
margin: 0 auto;
|
|
font-size: 26px;
|
|
line-height: 1.4;
|
|
width: 400px;
|
|
position: relative;
|
|
}
|
|
|
|
.truncate-text-multiline:after {
|
|
content: '';
|
|
position: absolute;
|
|
bottom: 0;
|
|
right: 0;
|
|
width: 150px;
|
|
height: 36.4px;
|
|
background: linear-gradient(to right, rgba(0, 0, 0, 0), #f5f6f9 50%);
|
|
}
|
|
```
|

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