#### Enable responsive
You can enable responsive classes for an existing set of utilities that are not currently responsive by default. For example, to make the `border` classes responsive:
```scss
@import "bootstrap/scss/functions";
@import "bootstrap/scss/variables";
@import "bootstrap/scss/utilities";
$utilities: map-merge(
$utilities, (
"border": map-merge(
map-get($utilities, "border"),
( responsive: true ),
),
)
);
```
This will now generate responsive variations of `.border` and `.border-0` for each breakpoint. Your generated CSS will look like this:
```css
.border { ... }
.border-0 { ... }
@media (min-width: 576px) {
.border-sm { ... }
.border-sm-0 { ... }
}
@media (min-width: 768px) {
.border-md { ... }
.border-md-0 { ... }
}
@media (min-width: 992px) {
.border-lg { ... }
.border-lg-0 { ... }
}
@media (min-width: 1200px) {
.border-xl { ... }
.border-xl-0 { ... }
}
@media (min-width: 1400px) {
.border-xxl { ... }
.border-xxl-0 { ... }
}
```
#### Rename utilities
Missing v4 utilities, or used to another naming convention? The utilities API can be used to override the resulting `class` of a given utility—for example, to rename `.ms-*` utilities to oldish `.ml-*`:
