A Bootstrap 5 reszponzív margók és padding segédprogramok széles skálájával rendelkezik. Minden törésponthoz működnek: xs (<=576px), sm (>=576px), md (>=768px), lg (>=992px), xl (>=1200px) vagy xxl (>=1400px)):

Az osztályok a következő formátumban használatosak: {property}{sides}-{size} az xs és < code class="w3-codespan">{property}{sides}-{breakpoint}-{size} for sm, md, lg, xl és xxl.

Ahol a tulajdon a következők egyike:

  • m - beállítja a margót

  • p - beállítja a kitöltést

Ahol az oldalak a következők egyike:

  • t - beállítja a margin-top vagy a feltöltést kód>

  • b - a margin-bottom vagy a padding-bottom beállítása kód>

  • s - beállítja a margin-left vagy a padding-left kód>

  • e - beállítja a margin-right vagy a padding-right-ot kód>

  • x - beállítja a padding-left és a padding-right vagy margin-left és margin-right

  • y - beállítja a padding-top és a padding-bottom vagy margin-top és margin-bottom

  • üres - beállít egy margót vagy kitöltést az elem mind a 4 oldalán

Ahol a méret a következők egyike:

  • 0 - a margót vagy a kitöltést a következőre állítja: < code class="w3-codespan">0

  • 1 - a margót vagy a kitöltést a következőre állítja: < code class="w3-codespan">.25rem

  • 2 - a margót vagy a kitöltést a következőre állítja: < code class="w3-codespan">.5rem

  • 3 - a margót vagy a kitöltést a következőre állítja: < code class="w3-codespan">1rem

  • 4 - a margót vagy a kitöltést a következőre állítja: < code class="w3-codespan">1.5rem

  • 5 - a margót vagy a kitöltést a következőre állítja: < code class="w3-codespan">3rem

  • auto - a margót automatikusra állítja

Példa

I only have a top padding (1.5rem)
I have a padding on all sides (3rem)
I have a margin on all sides (3rem) and a bottom padding (3rem)
<div class="pt-4 bg-warning">I only have a top padding (1.5rem)</div>

Függőleges igazítás

Használja az align- osztályokat az elemek igazításának módosításához (csak soron belüli, soron belüli blokk, soron belüli táblázat és táblázat cellaelemeknél működik):

Példa

baseline top middle bottom text-top text-bottom

Képarány

Hozzon létre érzékeny videókat vagy diavetítéseket a szülő szélessége alapján.

Adja hozzá a .ratio osztályt az Ön által választott .ratio-* képaránnyal együtt egy szülőelemhez, és adja hozzá a beágyazást (videót vagy iframe-et):

Példa

<!-- Aspect ratio 1:1 -->
<div class="ratio ratio-1x1">
  <iframe src="https://www.youtube.com/embed/tgbNymZ7vqY"></iframe>

<!-- Aspect ratio 4:3 -->

Láthatóság

Használja a .visible vagy .invisible osztályt az elemek láthatóságának szabályozására. Megjegyzés: Ezek az osztályok nem változtatják meg a CSS megjelenítési értékét. Csak a következőt adják hozzá: visibility:visible vagy visibility:hidden:

Példa

I am visible
     <div class="visible">I am visible</div>
<div class="invisible">I am 
      invisible</div>

  <div class="visible bg-success">I am visible</div>
  <div class="invisible bg-warning">I am invisible</div>

ikon bezárása

Használja a .btn-close osztályt a bezárási ikon stílusához. Ezt gyakran használják riasztásokhoz és módozatokhoz.

Példa

     <button type="button" class="btn-close"></button>

<div class="container mt-3">
  <h1>Close Icon</h1>
  <p>Use the .close class to style a close icon. This is often used for alerts and modals. Note that we use the times; symbol to create the actual icon (a better looking "x"). Also note that it is right-aligned by default:</p>
  <div class="clearfix">
    <button type="button" class="close">&amp;times;</button>
  </div>

Képernyőolvasók

Használja a .visually-hidden osztályt egy elem elrejtéséhez az összes eszközön, kivéve a képernyőolvasókat:

A fenti .bg-color osztályok nem működnek jól szöveggel, vagy legalábbis akkor meg kell adni a megfelelő .text-color osztályt, hogy minden háttérhez megfelelő szövegszínt kapjon.

Használhatja azonban a .text-bg-color osztályokat, és a Bootstrap automatikusan kezeli a megfelelő szövegszínt minden háttérszínhez:

Példa

This text is important.

This text indicates success.

This text represents some information.

This text represents a warning.

This text represents danger.

Secondary background color.

Dark grey background color.

Light grey background color.
