I have spent a day on the web trying to get bootstrap's media-breakpoint-only working without finding clear instructions.
I have the bootstrap navbar working so, I suspect, I have bootstrap installed correctly.
I want to get the following code working:
h1 {
@include media-breakpoint-only(xs) {
color: red;
}
@include media-breakpoint-only(sm) {
color: green;
}
@include media-breakpoint-only(md) {
color: blue;
}
@include media-breakpoint-only(lg) {
color: yellow;
}
@include media-breakpoint-only(xl) {
color: orange;
}
}
but I haven't a clue where to put this code or what additional things I need to do to get media-breakpoint-only working.
When I put the above code at the end of application.scss (see below), I get the following error:
Undefined mixin 'media-breakpoint-only'.
