Position
Bootstrap 5 Position
Use these helpers for quickly configuring the position of an element.
Basic examples
Fixed top
Position an element at the top of the viewport, from edge to edge. Be sure you understand the ramifications of fixed position in your project; you may need to add additional CSS.
<div class="fixed-top">...</div>
Fixed bottom
Position an element at the bottom of the viewport, from edge to edge. Be sure you understand the ramifications of fixed position in your project; you may need to add additional CSS.
<div class="fixed-bottom">...</div>
Sticky top
Position an element at the top of the viewport, from edge to edge, but only after you scroll
past it. The .sticky-top utility uses CSS’s position: sticky, which
isn’t fully supported in all browsers.
<div class="sticky-top">...</div>
Responsive sticky top
Responsive variations also exist for .sticky-top utility.
<div class="sticky-sm-top">Stick to the top on viewports sized SM (small) or wider</div>
<div class="sticky-md-top">Stick to the top on viewports sized MD (medium) or wider</div>
<div class="sticky-lg-top">Stick to the top on viewports sized LG (large) or wider</div>
<div class="sticky-xl-top">Stick to the top on viewports sized XL (extra-large) or wider</div>
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 verticaltoppositionleft- for the horizontalleftpositionbottom- for the verticalbottompositionright- for the horizontalrightposition
Where position is one of:
0- for0edge position50- for50%edge position100- for100%edge position
You can add more position values by adding entries to the $position-values Sass
map variable.
<div class="position-relative position-relative-example">
<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>
.position-relative-example {
height: 200px;
width: 100%;
background-color: #f5f5f5;
}
.position-relative-example div {
width: 2em;
height: 2em;
background-color: #343a40;
border-radius: .25rem;
}
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 position-relative-example">
<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>
.position-relative-example {
height: 200px;
width: 100%;
background-color: #f5f5f5;
}
.position-relative-example div {
width: 2em;
height: 2em;
background-color: #343a40;
border-radius: .25rem;
}
