.alert--test {
background-color: var(--primary);
}
}
@media (min-width: 576px) and (max-width: 991px) {
.alert--test {
background-color: var(--success);
}
}
@media (min-width: 992px) and (max-width: 1999px) {

}
}
@media (min-width: 1200px) {
.alert--test {
background-color: var(--danger);
}
}alert-primary col-xl-alert-danger и добавить уникальный класс, в моем случае это, например, alert--test. @media (max-width: 576px) {
.col-xl-alert-danger {
background: blue;
}
}
@media (min-width: 1200px) {
.col-xl-alert-danger {
background: red;
}
}
@media (min-width: 992px) and (min-width: 1200px) {
.col-xl-alert-danger {
background: yellow;
}
}
@media (min-width: 576px) and (min-width: 992px) {
.col-xl-alert-danger {
background: green;
}
}
