Constant width to height ratio

+

Given an element of variable width, it will ensure its height remains proportionate in a responsive fashion (i.e., its width to height ratio remains constant).

+

HTML

<div class="constant-width-to-height-ratio"></div>
+
+

CSS

.constant-width-to-height-ratio {
+  background: #333;
+  width: 50%;
+  padding-top: 50%;
+}
+
+

Demo

+

Resize your browser window to see the proportion of the element remain the same.

+
+
+
+ +

Explanation

+

padding-top and padding-bottom can be used as an alternative to height such that the percentage value causes an element's height to become a percentage of its width, i.e. 50% means the height + will be 50% of the element's width. This allows its proportion to remain constant.

+

Browser support

+
+
+ 99+% +
+
+

⚠️ padding-top pushes any content within the element to the bottom.
