## Takeaways
|
||
|
|
|
||
|
|
- Try to avoid using static media queries in your code
|
||
|
|
- Try to use the provided SCSS mixins
|
||
|
|
|
||
|
|
### ❌ Don't do this
|
||
|
|
|
||
|
|
Don't use static media queries in your code
|
||
|
|
|
||
|
|
```css
|
||
|
|
/**
|
||
|
|
* Don't do this
|
||
|
|
* Static box-shadows create inconsistency in elevation of elements
|
||
|
|
**/
|
||
|
|
.card {
|
||
|
|
box-shadow: 0 0 5px 0 rgba(0, 0, 0, 0.2);
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### ✅ Do this
|
||
|
|
|
||
|
|
Do use the provided shadow design token css variables
|
||
|
|
|
||
|
|
```css
|
||
|
|
.card {
|
||
|
|
box-shadow: var(--shadow-size-xs) var(--color-shadow-default);
|
||
|
|
}
|
||
|
|
```
|
||
|
