Bootstrap 5: Navigációs sávok

Tartalomjegyzék

Navigációs sávok

A navigációs sáv egy navigációs fejléc, amely az oldal tetején található:

Alapszintű navigációs sáv

A Bootstrap segítségével a navigációs sáv a képernyő méretétől függően meghosszabbítható vagy összecsukható.

Egy szabványos navigációs sáv jön létre a .navbar osztállyal, amelyet egy érzékeny összecsukható osztály követ: .navbar-expand-xxl| xl|lg|md|sm (a navigációs sáv függőleges elhelyezése xxlarge, extra nagy, nagy, közepes vagy kis képernyőkön).

Ha linkeket szeretne hozzáadni a navigációs sávhoz, használjon egy <ul> elemet (vagy egy <div>) class="navbar-nav". Ezután adjon hozzá <li> elemeket egy .nav-item osztállyal, amelyet egy <a> elem .nav-link osztállyal:

Példa

<!-- A grey horizontal navbar that becomes vertical on small screens -->
<nav class="navbar navbar-expand-sm bg-light">
  <div class="container-fluid">
    <!-- Links -->
    <ul class="navbar-nav">
      <li class="nav-item">
        <a class="nav-link" href="#">Link 1</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link 2</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link 3</a>
      </li>
    </ul>
  </div>
</nav>

  <h3>Basic Navbar Example</h3>
  <p>A navigation bar is a navigation header that is placed at the top of the page.</p>
  <p>The navbar-expand-xxl|xl|lg|md|sm class determines when the navbar should stack vertically (on xxlarge, extra large, large, medium or small screens).</p>
</div>

Függőleges Navbar

Távolítsa el a .navbar-expand-* osztályt egy mindig függőleges navigációs sáv létrehozásához:

<!-- A grey vertical navbar -->
<nav class="navbar bg-light">

Középre helyezett Navbar

Adja hozzá a .justify-content-center osztályt a navigációs sáv közepére:

<div class="container-fluid mt-3">
  <h3>Centered Navbar</h3>
  <p>Use the .justify-content-center class to center the navigation bar.</p>
  <p>In this example, the navbar will be centered on medium, large and extra large screens. On small screens it will be displayed vertically and left-aligned (because of the .navbar-expand-sm class).</p>
</div>

</body>
</html>

Színes Navbar

Használja bármelyik .bg-color osztályt a navigációs sáv háttérszínének módosításához

.bg-primary
.bg-success
.bg-info
.bg-warnig
.bg-danger
.bg-secondary
.bg-dark 
.bg-light

Tipp: Adjon hozzá fehér szövegszínt a navigációs sáv összes linkjéhez a .navbar-dark osztállyal, vagy használja a .navbar-light osztályt a fekete szövegszín hozzáadásához.

<!-- Grey with black text -->

</html>

Aktív/letiltott állapot: Adja hozzá a .active osztályt egy <a>-hoz elemet az aktuális hivatkozás kiemeléséhez, vagy a .disabled osztályt, amely jelzi, hogy a hivatkozás nem kattintható.

Márka/logó

A .navbar-brand osztály az oldal márka/logó/projekt nevének kiemelésére szolgál:

Példa

<nav class="navbar navbar-expand-sm bg-dark navbar-dark">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Logo</a>

Navbar szöveg

Használja a .navbar-text osztályt a navigációs sávon belüli azon elemek függőleges igazításához, amelyek nem hivatkozások (biztosítja a megfelelő kitöltést és a szöveg színét).

Példa

  <h3>Navbar Text</h3>
  <p>Use the .navbar-text class to vertical align any elements inside the navbar that are not links (ensures proper padding).</p>
</div>

</body>
</html>

Nagyon gyakran, különösen kis képernyőkön, el akarja rejteni a navigációs hivatkozásokat, és le kell cserélni egy gombbal, amelyre kattintáskor fel kell tüntetni őket.

Összecsukható navigációs sáv létrehozásához használjon egy gombot a következőkkel: class="navbar-toggler", data-bs-toggle="collapse" és data-bs-target="# thetarget. Ezután csomagolja be a navigációs sáv tartalmát (hivatkozásokat stb.) egy <div> elembe a class="collapse navbar-collapse" karakterlánccal, majd a data-bs-target a gombhoz: "thetarget".

Példa

<nav class="navbar navbar-expand-sm bg-dark navbar-dark">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Logo</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#collapsibleNavbar">

  <h3>Collapsible Navbar</h3>
  <p>In this example, the navigation bar is hidden on small screens and replaced by a button in the top right corner (try to re-size this window).</p>

  <p>Tip: You can also remove the .navbar-expand-md class to ALWAYS hide navbar links and display the toggler button.</p>

Tipp: A .navbar-expand-md osztályt is eltávolíthatja, hogy MINDIG elrejtse a navigációs sáv hivatkozásait, és megjelenítse a váltógombot.

Navigációs sáv legördülő menüvel

A navigációs sávok legördülő menüket is tartalmazhatnak:

Példa

<li class="nav-item dropdown">
  <a class="nav-link dropdown-toggle" href="#" role="button" data-bs-toggle="dropdown">Dropdown</a>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Link</a></li>

Javítva a navigációs sáv

A navigációs sáv az oldal tetején vagy alján is rögzíthető.

A rögzített navigációs sáv rögzített helyzetben (fent vagy alul) látható marad, függetlenül az oldal görgetésétől.

A .fixed-top osztály a navigációs sávot a következő helyen rögzíti felül:

Példa

<nav class="navbar navbar-expand-sm bg-dark navbar-dark fixed-top">
   …
</nav>

Használja a .sticky-top osztályt a navigációs sáv rögzítéséhez/az oldal tetejére maradásához, amikor múlt görget azt. Megjegyzés: Ez az osztály nem működik az IE11 és korábbi verziókban (a position:relativeként fogja kezelni).
