## Position values
2017-08-08 07:36:57 +02:00
Quick positioning classes are available, though they are not responsive.
2020-10-19 11:56:49 +02:00
```html
2017-08-08 07:36:57 +02:00
< 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 >
2020-10-19 11:56:49 +02:00
```
2020-09-21 04:42:41 +02:00
## 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
2020-06-09 15:44:20 +02:00
- `start` - for the horizontal `left` position (in LTR)
2020-09-21 04:42:41 +02:00
- `bottom` - for the vertical `bottom` position
2020-06-09 15:44:20 +02:00
- `end` - for the horizontal `right` position (in LTR)
2020-09-21 04:42:41 +02:00
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" >
2020-06-09 15:44:20 +02:00
< 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 >
2020-09-21 04:42:41 +02:00
< / 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" >
2020-06-09 15:44:20 +02:00
< 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 >
2020-09-21 04:42:41 +02:00
< / div >
{{< / example > }}
2020-11-29 15:58:20 +01:00
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.
{{< example class = "bd-example-position-examples" > }}
< div class = "position-relative m-4" >
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

* 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"
