+
+## 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 >}}
+
+## Examples
+
+Here are some real life examples of these classes:
+
+{{< example class="bd-example-position-examples d-flex justify-content-around align-items-center" >}}
+<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>
+
+<div class="position-relative py-2 px-4 text-bg-secondary border border-secondary rounded-pill">
+  Marker <svg width="1em" height="1em" viewBox="0 0 16 16" class="position-absolute top-100 start-50 translate-middle mt-1" fill="var(--bs-secondary)" 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>
+</div>
+
+<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>
+{{< /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">
+  <div class="progress" role="progressbar" aria-label="Progress" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100" style="height: 1px;">
+    <div class="progress-bar" style="width: 50%"></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>
+{{< /example >}}
