Hälytykset

Bootstrap 5 tarjoaa helpon tavan luoda ennalta määritettyjä hälytysviestejä:

Hälytykset luodaan .alert-luokalla, jota seuraa jokin asiayhteysluokista:

.alert-success
.alert-info
.alert-warning
.alert-danger
.alert-primary
.alert-secondary
.alert-light
.alert-dark

Esimerkki

<div class="alert alert-success">
  <strong>Success!</strong> Indicates a successful or positive action.
</div>

Sulkemishälytykset

Success! This alert box could indicate a successful or positive action.

Sulje hälytysviesti lisäämällä .alert-dismissible luokka hälytyssäiliöön. Lisää sitten class="btn-close" ja data-bs-dismiss="alert" linkkiin tai painikeelementtiin (kun napsautat tätä hälytysruutuun katoavat).

Esimerkki

 <div class="alert alert-success alert-dismissible">
  <button 
  type="button" class="btn-close" data-bs-dismiss="alert"></button>
  
  <strong>Success!</strong> This alert box could indicate a successful or 
  positive action.
