overflow

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The overflow attribute sets what to do when an element's content is too big to fit in its block formatting context. This feature is not widely implemented yet.

This attribute has the same parameter values and meaning as the CSS overflow property, however, the following additional points apply:

  • If it has a value of visible, the attribute has no effect (i.e., a clipping rectangle is not created).
  • If the overflow property has the value hidden or scroll, a clip of the exact size of the SVG viewport is applied.
  • When scroll is specified on an <svg> element, a scrollbar or panner is normally shown for the SVG viewport whether or not any of its content is clipped.
  • Within SVG content, the value auto implies that all rendered content for child elements must be visible, either through a scrolling mechanism, or by rendering with no clip.

Note: Although the initial value for overflow is auto, it is overwritten in the User Agent style sheet for the <svg> element when it is not the root element of a stand-alone document, the <pattern> element, and the <marker> element to be hidden by default.

Note: As a presentation attribute, overflow also has a CSS property counterpart: overflow. When both are specified, the CSS property takes priority.

You can use this attribute with the following SVG elements:

Example

html
<svg viewBox="0 0 200 30" xmlns="http://www.w3.org/2000/svg" overflow="auto">
  <text y="20">
    This text is wider than the SVG, so there should be a scrollbar shown.
  </text>
</svg>

Usage notes

Value visible | hidden | scroll | auto
Default value visible
Animatable Yes

For a description of the values, please see the CSS overflow property.
