The width attribute defines the horizontal length of an element in the user coordinate system.

You can use this attribute with the following SVG elements:

Example

<svg viewBox="0 0 100 300" xmlns="http://www.w3.org/2000/svg">
  <!-- With a width of 0 or less, nothing will be rendered -->
  <rect x="0" y="0" width="0" height="90" />
  <rect x="0" y="100" width="60" height="90" />
  <rect x="0" y="200" width="100%" height="90" />
</svg>
