Using Bootstrap classes within a specified class declaration

Can you nest style classes within a single class?

For example:

.my-upper-class{ .hidden-md, .hidden-sm, .hidden-lg}

Answer №1

Instead of using plain CSS, you can achieve this with Sass by doing the following:

.hidden-sm {
  background: red;
}

.hidden-md {
  color: blue;
}

.hidden-lg {
  font-size: 1em;
}

.my-upper-class {
  @extend .hidden-sm;
  @extend .hidden-md;
  @extend .hidden-lg;
}

This will generate the final CSS shown below, which aligns with your requirements.

.hidden-sm, .my-upper-class {
  background: red;
}

.hidden-md, .my-upper-class {
  color: blue;
}

.hidden-lg, .my-upper-class {
  font-size: 1em;
}
