Use these shorthand utilities for quickly configuring the position of an element.
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.)
<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.
<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>
Examples
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>
<button type="button" class="btn btn-dark position-relative">
Marker <svg width="1em" height="1em" viewBox="0 0 16 16" class="position-absolute top-100 start-50 translate-middle mt-1 bi bi-caret-down-fill" fill="#212529" 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>
</button>
<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" style="height: 1px;">
<div class="progress-bar" role="progressbar" style="width: 50%;" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></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>
