Bootstrap 5: Offcanvas

Innehållsförteckning

Offcanvas

  <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>

Exempel förklarat

Klassen .offcanvas skapar sidofältet offcanvas.

Klassen .offcanvas-start placerar offcanvasen och gör den 400px bred. Se exempel nedan för fler positioneringsklasser.

Klassen .offcanvas-title säkerställer korrekta marginaler och radhöjd.

Lägg sedan till ditt innehåll i klassen .offcanvas-body.

För att öppna sidofältet offcanvas måste du använda ett <button> eller ett ><a>-element som pekar på ID:t för .offcanvas-behållaren (#demo i vårt exempel).

För att öppna sidofältet offcanvas med ett <a>-element kan du peka på #demo med href-attributet , istället för attributet data-bs-target.

Offcanvas position

Använd .offcanvas-start|end|top|bottom för att placera offcanvasen till vänster, höger, upptill eller nedtill:

Rätt exempel

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

Some text lorem ipsum.

Responsiv OffCanvas-meny

Du kan också styra när du vill dölja eller visa offcanvas-menyn på olika skärmbredder, med klasserna .offcanvas-sm|md|lg|xl|xxl:

Exempel

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

<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>

Mörk OffCanvas-meny

Använd klassen .text-bg-dark för att skapa en mörk offcanvas meny.

Tips: Vi har också lagt till klassen .btn-close-white till .btn-close, för att skapa en vit stängningsknapp som ser snygg ut med mörker bakgrund:

Exempel

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

  <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
