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 |
|---|---|
| โ | Increase by 1 |
| โ | Decrease by 1 |
| alt + โ | Increase by 0.1 |
| alt + โ | Decrease by 0.1 |
| shift + โ | Increase by 10 |
| shift + โ | Decrease by 10 |
| cmd + โ | Increase by 100 |
| cmd + โ | Decrease by 100 |
On Windows and Linux, the cmd key should be replaced with the ctrl key.
