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 easily with the edge positioning utilities. The format is {property}-{position}.
Where property is one of:
top - for the vertical top positionstart - for the horizontal left position (in LTR)bottom - for the vertical bottom positionend - for the horizontal right position (in LTR)Where position is one of:
0 - for 0 edge position50 - for 50% edge position100 - for 100% edge position(You can add more position values by adding entries to the $position-values Sass map variable.)
<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>
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.
<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.
<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>
Here are some real life examples of these classes:
<button type="button" class="btn btn-primary position-relative"> Mails <span class="position-absolute top-0 start-100 translate-middle badge rounded-pill 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(--bs-secondary)" xmlns="http://www.w3.org/2000/svg"><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.
<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>
Default position utility values are declared in a Sass map, then used to generate our utilities.
$position-values: ( 0: 0, 50: 50%, 100: 100% );
Position utilities are declared in our utilities API in scss/_utilities.scss. Learn how to use the utilities API.
