Proč vkládáme # do atributu href odkazu?

Protože nemáme žádnou stránku, na kterou bychom mohli odkazovat, a nechceme dostávat „404“ zprávu, vložíme # jako odkaz. V reálném životě by to samozřejmě měla být skutečná adresa URL na stránku „Vyhledat“.

Obrys tlačítka

Bootstrap 5 také nabízí osm tlačítek s obrysem/ohraničením.

Přesuňte na ně ukazatel myši, abyste viděli další efekt „umístění kurzoru“:

Příklad

<button type="button" class="btn btn-outline-primary">Primary</button><button type="button" class="btn btn-outline-secondary">Secondary</button>
<button type="button" class="btn btn-outline-success">Success</button>
<button type="button" class="btn btn-outline-info">Info</button>
<button type="button" class="btn btn-outline-warning">Warning</button>
<button type="button" class="btn btn-outline-danger">Danger</button>
<button type="button" class="btn btn-outline-dark">Dark</button>
<button type="button" class="btn btn-outline-light text-dark">Light</button>

Velikosti tlačítek

Použijte třídu .btn-lg pro velká tlačítka nebo třídu .btn-sm pro malá tlačítka:

Příklad

<button type="button" class="btn btn-primary btn-lg">Large</button>
<button type="button" class="btn btn-primary">Default</button>
<button type="button" class="btn btn-primary btn-sm">Small</button>

Blokovat tlačítka úrovně

Chcete-li vytvořit tlačítko na úrovni bloku, které se rozprostírá po celé šířce nadřazeného prvku, použijte na nadřazeném prvku třídu "helper" .d-grid:

Příklad

<div class="d-grid">
	  <button type="button" class="btn btn-primary btn-block">Full-Width Button</button>
</div>

  <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.3/dist/js/bootstrap.bundle.min.js"></script>
</head>
<body>

<div class="container mt-3">
  <h2>Block Level Buttons</h2>
  <p>To create a block level button that spans the entire width of the parent element, use the .d-grid "helper" class on the parent element:</p>
  <div class="d-grid">
    <button type="button" class="btn btn-primary btn-block">Full-Width Button</button>
  </div>
</div>

</body>
</html>

Pokud máte mnoho tlačítek na úrovni bloku, můžete mezeru mezi nimi ovládat pomocí třídy .gap-*:

Příklad

<div class="d-grid gap-3">
  <button type="button" class="btn btn-primary btn-block">Full-Width Button</button>
  <button type="button" class="btn btn-primary btn-block">Full-Width Button</button>
  <button type="button" class="btn btn-primary btn-block">Full-Width Button</button>
</div>

<div class="container mt-3">
  <h2>Block Level Buttons</h2>
  <p>If you have many block-level buttons, you can control the space between them with the .gap-* class:</p>
  <div class="d-grid gap-3">
    <button type="button" class="btn btn-primary btn-block">Full-Width Button</button>
    <button type="button" class="btn btn-primary btn-block">Full-Width Button</button>
    <button type="button" class="btn btn-primary btn-block">Full-Width Button</button>
  </div>
</div>

</body>
</html>

Aktivní/deaktivovaná tlačítka

Tlačítko lze nastavit do aktivního (zobrazí se stisknutého) nebo deaktivovaného (neklikatelné) stavu:

Třída .active způsobí, že tlačítko vypadá jako stisknuté, a atribut disabled způsobí, že na tlačítko nelze kliknout. Všimněte si, že prvky <a> nepodporují atribut disabled, a proto musí používat třídu .disabled, aby vizuálně vypadaly jako deaktivované.

Příklad

<button type="button" class="btn btn-primary active">Active Primary</button>
<button type="button" class="btn btn-primary" disabled>Disabled Primary</button>
<a href="#" class="btn btn-primary disabled">Disabled Link</a>

  <button type="button" class="btn btn-primary" disabled>Disabled Primary</button>
  <a href="#" class="btn btn-primary disabled">Disabled Link</a>
</div>

Spinner Buttons

K tlačítku můžete také přidat "spinnery", o kterých se dozvíte více v našem BS5 Spinner Tutorial:

Příklad

   <button class="btn btn-primary">
  <span class="spinner-border 
    spinner-border-sm"></span>
</button>
<button class="btn 
    btn-primary">
  <span class="spinner-border 
    spinner-border-sm"></span>
  Loading..
</button>
<button 
    class="btn btn-primary" disabled>
  <span class="spinner-border 
    spinner-border-sm"></span>
  Loading..
</button>
    
<button class="btn btn-primary" disabled>
  <span 
    class="spinner-grow spinner-grow-sm"></span>
  Loading..
    </button>
