Sut maen nhw'n gweithio

Gwteri yw'r bylchau rhwng cynnwys colofn, a grëir gan lorweddol padding. Rydym yn gosod padding-rightac padding-leftar bob colofn, ac yn defnyddio negatif margini wrthbwyso hynny ar ddechrau a diwedd pob rhes i alinio cynnwys.
Mae cwteri yn dechrau ar 1.5rem( 24px) led. Mae hyn yn ein galluogi i baru ein grid â'r raddfa padin a bylchau ymyl .
Gellir addasu cwteri yn ymatebol. Defnyddiwch ddosbarthiadau cwteri torbwynt penodol i addasu cwteri llorweddol, cwteri fertigol, a phob cwter.

Gwteri llorweddol

.gx-*gellir defnyddio dosbarthiadau i reoli lled y cwteri llorweddol. Efallai y bydd angen addasu'r rhiant .containerneu'r .container-fluidrhiant os defnyddir cwteri mwy hefyd i osgoi gorlifiad diangen, gan ddefnyddio cyfleustodau padin cyfatebol. Er enghraifft, yn yr enghraifft ganlynol rydym wedi cynyddu'r padin gyda .px-4:

Padin colofn personol

html

<div class="container px-4 text-center">
  <div class="row gx-5">
    <div class="col">
     <div class="p-3 border bg-light">Custom column padding</div>
    </div>
    <div class="col">
      <div class="p-3 border bg-light">Custom column padding</div>
    </div>
  </div>
</div>

Ateb arall yw ychwanegu papur lapio o amgylch y .rowgyda'r .overflow-hiddendosbarth:

<div class="container overflow-hidden text-center">
  <div class="row gx-5">
    <div class="col">
     <div class="p-3 border bg-light">Custom column padding</div>
    </div>
    <div class="col">
      <div class="p-3 border bg-light">Custom column padding</div>
    </div>
  </div>
</div>

Gwteri fertigol

.gy-* classes can be used to control the vertical gutter widths within a row when columns wrap to new lines. Like the horizontal gutters, the vertical gutters can cause some overflow below the .row at the end of a page. If this occurs, you add a wrapper around .row with the .overflow-hidden class:

Custom column padding

html

<div class="container overflow-hidden text-center">
  <div class="row gy-5">
    <div class="col-6">
      <div class="p-3 border bg-light">Custom column padding</div>
    </div>
    <div class="col-6">
      <div class="p-3 border bg-light">Custom column padding</div>
    </div>
    <div class="col-6">
      <div class="p-3 border bg-light">Custom column padding</div>
    </div>
    <div class="col-6">
      <div class="p-3 border bg-light">Custom column padding</div>
    </div>
  </div>
</div>

Horizontal & vertical gutters

.g-* classes can be used to control the horizontal gutter widths, for the following example we use a smaller gutter width, so there won’t be a need to add the .overflow-hidden wrapper class.

Custom column padding

html

<div class="container text-center">
  <div class="row g-2">
    <div class="col-6">
      <div class="p-3 border bg-light">Custom column padding</div>
    </div>
    <div class="col-6">
      <div class="p-3 border bg-light">Custom column padding</div>
    </div>
    <div class="col-6">
      <div class="p-3 border bg-light">Custom column padding</div>
    </div>
    <div class="col-6">
      <div class="p-3 border bg-light">Custom column padding</div>
    </div>
  </div>
</div>

Row columns gutters

Gutter classes can also be added to row columns. In the following example, we use responsive row columns and responsive gutter classes.

Row column

html

<div class="container text-center">
  <div class="row row-cols-2 row-cols-lg-5 g-2 g-lg-3">
    <div class="col">
      <div class="p-3 border bg-light">Row column</div>
    </div>
    <div class="col">
      <div class="p-3 border bg-light">Row column</div>
    </div>
    <div class="col">
      <div class="p-3 border bg-light">Row column</div>
    </div>
    <div class="col">
      <div class="p-3 border bg-light">Row column</div>
    </div>
    <div class="col">
      <div class="p-3 border bg-light">Row column</div>
    </div>
    <div class="col">
      <div class="p-3 border bg-light">Row column</div>
    </div>
    <div class="col">
      <div class="p-3 border bg-light">Row column</div>
    </div>
    <div class="col">
      <div class="p-3 border bg-light">Row column</div>
    </div>
    <div class="col">
      <div class="p-3 border bg-light">Row column</div>
    </div>
    <div class="col">
      <div class="p-3 border bg-light">Row column</div>
    </div>
  </div>
</div>

No gutters

The gutters between columns in our predefined grid classes can be removed with .g-0. This removes the negative margins from .row and the horizontal padding from all immediate children columns.

Need an edge-to-edge design? Drop the parent .container or .container-fluid and add .mx-0 to the .row to prevent overflow.

In practice, here’s how it looks. Note you can continue to use this with all other predefined grid classes (including column widths, responsive tiers, reorders, and more).

.col-sm-6 .col-md-8

.col-6 .col-md-4

html

<div class="row g-0 text-center">
  <div class="col-sm-6 col-md-8">.col-sm-6 .col-md-8</div>
  <div class="col-6 col-md-4">.col-6 .col-md-4</div>
</div>

Change the gutters

Classes are built from the $gutters Sass map which is inherited from the $spacers Sass map.

$grid-gutter-width: 1.5rem;
$gutters: (
  0: 0,
  1: $spacer * .25,
  2: $spacer * .5,
  3: $spacer,
  4: $spacer * 1.5,
  5: $spacer * 3,
);
