Bootstrap 5: Offcanvas

Indholdsfortegnelse

Offcanvas

Offcanvas ligner modals (skjult som standard og vises, når det er aktiveret), bortset fra at det ofte bruges som en sidebar navigationsmenu.

Some text lorem ipsum.

Sådan opretter du en Offcanvas-sidebjælke

Følgende eksempel viser, hvordan man opretter en offcanvas-sidebjælke:

Eksempel

 <!-- Offcanvas Sidebar -->
<div class="offcanvas offcanvas-start" 
  id="demo">
  <div 
  class="offcanvas-header">
    <h1 
  class="offcanvas-title">Heading</h1>
    <button 
  type="button" class="btn-close text-reset" 
  data-bs-dismiss="offcanvas"></button>
  </div>
  <div 
  class="offcanvas-body">
    <p>Some text lorem ipsum.</p>
    
  <p>Some text lorem ipsum.</p>
    <button class="btn 
  btn-secondary" type="button">A Button</button>
  </div>
</div>

  <h3>Offcanvas Sidebar</h3>
  <p>Offcanvas is similar to modals, except that it is often used as a sidebar.</p>
  <button class="btn btn-primary" type="button" data-bs-toggle="offcanvas" data-bs-target="#demo">
    Open Offcanvas Sidebar
  </button>
</div>

</body>

Eksempel forklaret

Klassen .offcanvas opretter offcanvas-sidebjælken.

Klassen .offcanvas-start placerer offcanvasen og gør den 400px bred. Se eksempler nedenfor for flere positioneringsklasser.

Klassen .offcanvas-title sikrer korrekte margener og linjehøjde.

Tilføj derefter dit indhold i klassen .offcanvas-body.

For at åbne offcanvas-sidebjælken skal du bruge et <button> eller et ><a>-element, der peger på id'et for .offcanvas-beholderen (#demo i vores eksempel).

For at åbne offcanvas-sidebjælken med et <a>-element kan du pege på #demo med href-attributten , i stedet for attributten data-bs-target.

Offcanvas position

Brug .offcanvas-start|end|top|bottom til at placere offcanvas til venstre, højre, top eller bund:

Rigtigt eksempel

<div class="offcanvas offcanvas-end" id="demo">

Some text lorem ipsum.

Responsiv OffCanvas-menu

Du kan også styre, hvornår du vil skjule eller vise offcanvas-menuen på forskellige skærmbredder, med .offcanvas-sm|md|lg|xl|xxl klasserne:

Eksempel

 <div class="offcanvas offcanvas-start offcanvas-lg" id="demo">

  <div class="offcanvas-header">
    <h1 class="offcanvas-title">Heading</h1>
    <button type="button" class="btn-close" data-bs-dismiss="offcanvas"></button>

  <div class="offcanvas-body">

    <p>Some text lorem ipsum.</p>
    <p>Some text lorem ipsum.</p>
    <button class="btn btn-secondary" type="button">A Button</button>
  </div>
</div>

<div class="container-fluid mt-3">
  <h3>Responsive Offcanvas Menu</h3>
  <p>You can also hide or show the offcanvas menu on different screen widths, with the .offcanvas-sm|md|lg|xl|xxl classes.</p>
  <p>In this example, we hide the offcanvas menu on screens larger than 991px wide. Note that we also hide the button that opens the offcanvas (d-lg-none).</p>
  <p class="text-bg-danger">Resize the browser window to see the result.</p>
  <button class="btn btn-primary d-lg-none" type="button" data-bs-toggle="offcanvas" data-bs-target="#demo">
    Open Offcanvas Sidebar
  </button>
</div>

</body>
</html>

Mørk OffCanvas-menu

Brug klassen .text-bg-dark til at oprette en mørk offcanvas menu.

Tip: Vi har også tilføjet klassen .btn-close-white til .btn-close for at skabe en hvid lukkeknap, der ser flot ud i mørke baggrund:

Eksempel

<div class="offcanvas offcanvas-end" id="demo">
<button type="button" class="btn-close btn-close-white" data-bs-dismiss="offcanvas"></button>

Some text lorem ipsum.

  <h3>Dark Offcanvas Sidebar</h3>
  <p>Use the .text-bg-dark class to create a dark offcanvas menu.</p>
  <p><strong>Tip:</strong> We have also added the .btn-close-white class to .btn-close, to create a white close button that looks nice with the dark background:</p>
  <button class="btn btn-primary" type="button" data-bs-toggle="offcanvas" data-bs-target="#demo">
    Open Offcanvas Sidebar
  </button>
</div>
