<p>« <a href="/en/SVG/Attribute" title="en/SVG/Attribute">SVG Attribute reference home</a></p>
<p>The <code>overflow</code> attribute has the same parameter values as defined for the {{ cssxref("overflow","CSS overflow property") }}. However, the following additional points apply:</p>
<ul>
<li>The <code>overflow</code> attribute only applies to elements that establish new viewports (see below), {{ SVGElement("pattern") }} elements and {{ SVGElement("marker") }} elements. For all other elements, the property has no effect.</li>
<li>For those elements to which the <code>overflow</code> attribute can apply, if the <code>overflow</code> attribute has the value <code>hidden</code> or <code>scroll</code>, the effect is that a new clipping path in the shape of a rectangle is created. The result is equivalent to defining a {{ SVGElement("clipPath") }} element whose content is a {{ SVGElement("rect") }} element which defines the equivalent rectangle, and then specifying the <uri> of this {{ SVGElement("clipPath") }} element on the {{ SVGAttr("clip-path") }} attribute for the given element.</li>
<li>If the <code>overflow</code> attribute has a value other than <code>hidden</code> or <code>scroll</code>, the property has no effect.</li>
<li>Within SVG content, the value <code>auto</code> is equivalent to the value <code>visible</code>.</li>
<li>When an outermost svg element is embedded inline within HTML, if the <code>overflow</code> attribute has the value <code>hidden</code> or <code>scroll</code>, then the browser will establish an initial clipping path equal to the bounds of the initial viewport; otherwise, the initial clipping path is set according to the CSS clipping rules.</li>
<li>When an outermost svg element is stand-alone, the <code>overflow</code> attribute on the outermost svg element is ignored for the purposes of visual rendering and the initial clipping path is set to the bounds of the initial viewport.</li>
<li>The initial value for <code>overflow</code> as defined in CSS is <code>visible</code>, and this applies also to the root {{ SVGElement("svg") }} element; however, for child elements of an SVG document, SVG's browser style sheet overrides this initial value and sets the <code>overflow</code> attribute on elements that establish new viewports, ‘pattern’ elements and ‘marker’ elements to the value <code>hidden</code>.</li>
</ul>
<p>As a presentation attribute, it also can be used as a property directly inside a CSS stylesheet, see {{ cssxref("overflow","CSS overflow") }} for further information.</p>
