docs Position Use these shorthand utilities for quickly configuring the position of an element. utilities true

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.)

{{< example class="bd-example-position-utils" >}}

{{< /example >}}

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.

{{< example class="bd-example-position-utils" >}}

{{< /example >}}

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

{{< example class="bd-example-position-utils" >}}

{{< /example >}}

Examples

Here are some real life examples of these classes:

{{< example class="bd-example-position-examples d-flex justify-content-around align-items-center" >}} Mails +99 unread messages

Marker
Alerts unread messages {{< /example >}}

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.

{{< example class="bd-example-position-examples" >}}

Sass

Maps

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

{{< scss-docs name="position-map" file="scss/_variables.scss" >}}

Utilities API

Position utilities are declared in our utilities API in scss/_utilities.scss. [Learn how to use the utilities API.]({{< docsref "/utilities/api#using-the-api" >}})
