Figyelmeztetések

A Bootstrap 5 egyszerű módot biztosít előre meghatározott figyelmeztető üzenetek létrehozására:

A riasztások a .alert osztállyal jönnek létre, amelyet a környezetfüggő osztályok egyike követ:

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

Példa

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

Figyelmeztető hivatkozások

Adja hozzá az .alert-link osztályt a figyelmeztető mezőben lévő bármely hivatkozáshoz, hogy "egyező színű linkeket" hozzon létre:

Példa

<div class="alert alert-success">
  <strong>Success!</strong> You should <a href="#" class="alert-link">read this message</a>.

Záró figyelmeztetések

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

A figyelmeztető üzenet bezárásához adjon hozzá egy .alert-dismissible kódot. osztályt a riasztási tárolóba. Ezután adja hozzá a class="btn-close" és a data-bs-dismiss="alert" hivatkozásra vagy gombelemre (ha rákattint, a figyelmeztető mező megjelenik eltűnik).

Példa

 <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.
