+### Circle
+
+Creates a circle shape with pure CSS.
+
+#### HTML
+
+```html
+<div class="circle"></div>
+```
+
+#### CSS
+
+```css
+.circle {
+  border-radius: 50%;
+  width: 2rem;
+  height: 2rem;
+  background: #333;
+}
+```
+
+#### Demo
+
+<div class="snippet-demo">
+  <div class="snippet-demo__circle"></div>
+</div>
+
+<style>
+.snippet-demo__circle {
+  border-radius: 50%;
+  width: 2rem;
+  height: 2rem;
+  background: #333;
+}
+</style>
+
+#### Explanation
+
+`border-radius: 50%` curves the borders of an element to create a circle.
+
+Since a circle has the same radius at any given point, the `width` and `height` must be the same. Differing
+values will create an ellipse.

+#### Browser support
