width

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

Twenty five elements are using this attribute: <feBlend>, <feColorMatrix>, <feComponentTransfer>, <feComposite>, <feConvolveMatrix>, <feDiffuseLighting>, <feDisplacementMap>, <feDropShadow>, <feFlood>, <feGaussianBlur>, <feImage>, <feMerge>, <feMorphology>, <feOffset>, <feSpecularLighting>, <feTile>, <feTurbulence>, <filter>, <foreignObject>, <image>, <mask>, <pattern>, <rect>, <svg>, and <use>

<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>

filter

For <filter>, width defines the horizontal length for the rendering area of the filter.

foreignObject

For <foreignObject>, width defines the horizontal length for the rendering area for the referenced document.

Note: Starting with SVG2, width is a Geometry Property meaning this attribute can also be used as a CSS property for <foreignObject>.

image

For <image>, width defines the horizontal length for the image.

Note: Starting with SVG2, width is a Geometry Property meaning this attribute can also be used as a CSS property for images.

mask

For <mask>, width defines the horizontal length of its area of effect. The exact effect of this attribute is influenced by the maskUnits attribute.

pattern

For <pattern>, width defines the horizontal length of the tile pattern. The exact effect of this attribute is influenced by the patternUnits and patternTransform attributes.

rect

For <rect>, width defines the horizontal length for the rectangle.

Note: Starting with SVG2, width is a Geometry Property meaning this attribute can also be used as a CSS property for rectangles.

svg

For <svg>, width defines the horizontal length for the rendering area of the SVG viewport.

Note: In an HTML document if both the viewBox and width attributes are omitted, the svg element will be rendered with a width of 300px

Note: Starting with SVG2, width is a Geometry Property meaning this attribute can also be used as a CSS property for <svg>.

use

For <use>, width defines the horizontal length for the referenced element.
