Position values

Quick positioning classes are available, though they are not responsive.

<div class="position-static">...</div> <div class="position-relative">...</div> <div class="position-absolute">...</div> <div class="position-fixed">...</div> <div class="position-sticky">...</div>

Arrange elements

Arrange elements easily with the edge positioning utilities. The format is {property}-{position}.

Where property is one of:

top - for the vertical top position
start - for the horizontal left position (in LTR)
bottom - for the vertical bottom position
end - for the horizontal right position (in LTR)

Where position is one of:

0 - for 0 edge position
50 - for 50% edge position
100 - for 100% edge position

(You can add more position values by adding entries to the $position-values Sass map variable.)

html

<div class="position-relative">  <div class="position-absolute top-0 start-0"></div>  <div class="position-absolute top-0 end-0"></div>  <div class="position-absolute top-50 start-50"></div>  <div class="position-absolute bottom-50 end-50"></div>  <div class="position-absolute bottom-0 start-0"></div>  <div class="position-absolute bottom-0 end-0"></div> </div>

Center elements

In addition, you can also center the elements with the transform utility class .translate-middle.

This class applies the transformations translateX(-50%) and translateY(-50%) to the element which, in combination with the edge positioning utilities, allows you to absolute center an element.

html

<div class="position-relative">  <div class="position-absolute top-0 start-0 translate-middle"></div>  <div class="position-absolute top-0 start-50 translate-middle"></div>  <div class="position-absolute top-0 start-100 translate-middle"></div>  <div class="position-absolute top-50 start-0 translate-middle"></div>  <div class="position-absolute top-50 start-50 translate-middle"></div>  <div class="position-absolute top-50 start-100 translate-middle"></div>  <div class="position-absolute top-100 start-0 translate-middle"></div>  <div class="position-absolute top-100 start-50 translate-middle"></div>  <div class="position-absolute top-100 start-100 translate-middle"></div> </div>

By adding .translate-middle-x or .translate-middle-y classes, elements can be positioned only in horizontal or vertical direction.

html

<div class="position-relative">  <div class="position-absolute top-0 start-0"></div>  <div class="position-absolute top-0 start-50 translate-middle-x"></div>  <div class="position-absolute top-0 end-0"></div>  <div class="position-absolute top-50 start-0 translate-middle-y"></div>  <div class="position-absolute top-50 start-50 translate-middle"></div>  <div class="position-absolute top-50 end-0 translate-middle-y"></div>  <div class="position-absolute bottom-0 start-0"></div>  <div class="position-absolute bottom-0 start-50 translate-middle-x"></div>  <div class="position-absolute bottom-0 end-0"></div> </div>

Examples

Here are some real life examples of these classes:

Marker

html

<button type="button" class="btn btn-primary position-relative">  Mails <span class="position-absolute top-0 start-100 translate-middle badge rounded-pill text-bg-secondary">+99 <span class="visually-hidden">unread messages</span></span> </button>  <div class="position-relative py-2 px-4 text-bg-secondary border border-secondary rounded-pill">  Marker <svg width="1em" height="1em" viewBox="0 0 16 16" class="position-absolute top-100 start-50 translate-middle mt-1" fill="var(--cui-secondary)" xmlns="http://www.w3.org/2000/svg" aria-hidden="true"><path d="M7.247 11.14L2.451 5.658C1.885 5.013 2.345 4 3.204 4h9.592a1 1 0 0 1 .753 1.659l-4.796 5.48a1 1 0 0 1-1.506 0z"/></svg> </div>  <button type="button" class="btn btn-primary position-relative">  Alerts <span class="position-absolute top-0 start-100 translate-middle badge border border-light rounded-circle bg-danger p-2"><span class="visually-hidden">unread messages</span></span> </button>

You can use these classes with existing components to create new ones. Remember that you can extend its functionality by adding entries to the $position-values variable.

html

<div class="position-relative m-4">  <div class="progress" role="progressbar" aria-label="Progress" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100" style="height: 1px;">  <div class="progress-bar" style="width: 50%"></div>  </div>  <button type="button" class="position-absolute top-0 start-0 translate-middle btn btn-sm btn-primary rounded-pill" style="width: 2rem; height:2rem;">1</button>  <button type="button" class="position-absolute top-0 start-50 translate-middle btn btn-sm btn-primary rounded-pill" style="width: 2rem; height:2rem;">2</button>  <button type="button" class="position-absolute top-0 start-100 translate-middle btn btn-sm btn-secondary rounded-pill" style="width: 2rem; height:2rem;">3</button> </div>

Sass

Maps

Default position utility values are declared in a Sass map, then used to generate our utilities.

scss/_variables.scss

$position-values: (  0: 0,  50: 50%,  100: 100% );

Utilities API

Position utilities are declared in our utilities API in scss/_utilities.scss. Learn how to use the utilities API.

scss/_utilities.scss
