## Position values
Quick positioning classes are available, though they are not responsive.
```html
<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" >}}
<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>
{{< /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" >}}
<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>
{{< /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" >}}
<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>
{{< /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.

Rework progress bar markup and styles (#36831) * Rework progress bar markup and styles Logically moves the various `role` and `aria-` attributes to the `.progress` element itself, leaving the `.progress-bar` to be used purely for the visual presentation. This fixes the problem #36736 that in certain browser/AT combinations, zero-value/zero-width progress bars are completely ignored and not announced. For multiple/stacked progress bars, this PR introduces a new wrapper and class `.progress-stacked`, to accommodate for the fact that with the more logical structure above, we need full `.progress` elements with child `.progress-bar` elements, and can't get away with the fudge we had before of having a single `.progress` with multiple `.progress-bar`s. Note that the old markup structures still work with this change, so this could be considered a non-breaking change - though one we definitely want to highlight as it's more accessible (as it now guarantees that zero-value/zero-width progress bars, whether on their own or as part of a multi/stacked bar, are actually announced) * Add a note about progress bar change in migration guide * Add notes with old markup examples and explanation * Fix bundlewatch * Update site/content/docs/5.2/components/progress.md Co-authored-by: Julien Déramond <julien.deramond@orange.com> * Reintroduce deleted styles Turns out they're needed for correct positioning of text inside progress bar * Move changes in markup to Migrationg guide, link to that from top of progress page, rewrite some content * Fix typo in callout * Clarify "Sizing" section * Remove redundant "now" Co-authored-by: Julien Déramond <julien.deramond@orange.com> Co-authored-by: Julien Déramond <juderamond@gmail.com> Co-authored-by: Mark Otto <markdotto@gmail.com> Co-authored-by: Mark Otto <markd.otto@gmail.com>

## 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" >}})
