There are some CSS properties whose values contain numbers, such as height, font-size, margin, padding, width, etc.
Rather than changing the value manually, we can quickly increase or decrease the value by using one of the following key combinations:
| Key combinations | Value change |
|---|---|
| ↑ | Increase by 1 |
| ↓ | Decrease by 1 |
| alt + ↑ | Increase by 0.1 |
| alt + ↓ | Decrease by 0.1 |
| shift + ↑ | Increase by 10 |
| shift + ↓ | Decrease by 10 |
| cmd + ↑ | Increase by 100 |
| cmd + ↓ | Decrease by 100 |
On Windows and Linux, the cmd key should be replaced with the ctrl key.
