|
||
.phone {
|
||
&_title {
|
||
width: 500px;
|
||
@media (max-width: 500px) {
|
||
width: auto;
|
||
}
|
||
body.is_dark & {
|
||
color: white;
|
||
}
|
||
}
|
||
img {
|
||
display: block;
|
||
}
|
||
}
|
||
|
||
.title {
|
||
font-size: var(--font);
|
||
|
||
@at-root html {
|
||
--font: 16px
|
||
}
|
||
}
|
||
```
|
||
|
||
will be processed to:
|
||
|
||
```css
|
||
.phone_title {
|
||
width: 500px;
|
||
}
|
||
@media (max-width: 500px) {
|
