-<h2 id="VisibilityControl">Controlling visibility</h2>
-
-<p>SVG uses two properties, <a>'display'</a> and <a>'visibility'</a>, to
-control the visibility of graphical elements or (in the case of the
-<a>'display'</a> property) container elements.  The differences between the two
-properties are as follows.</p>
-
-<p>When applied to a container element, setting <a>'display'</a>
-to <span class="prop-value">none</span> causes the container and
-all of its children to be invisible; thus, it acts on groups of
-elements as a group. <a>'visibility'</a>, however, only applies
-to individual graphics elements. Setting <a>'visibility'</a>
-to <span class="prop-value">hidden</span> on a <a>'g'</a>
-will make its children invisible as long as the children do
-not specify their own <a>'visibility'</a> properties as <span
-class="prop-value">visible</span>. Note that <a>'display'</a> is
-<em>not</em> an inheritable property.</p>
-
-<p>When the <a>'display'</a> property is set to <span
-class="prop-value">none</span>, then the given element does not
-become part of the rendering tree. With <a>'visibility'</a> set
-to <span class="prop-value">hidden</span>, however, processing
-occurs as if the element were part of the rendering tree and still
-taking up space, but not actually rendered onto the canvas. This
-distinction has implications for the <a>'tspan'</a>, <a>'tref'</a> and
-<a>'altGlyph'</a> elements, <a href="interact.html#UIEvents">event processing</a>,
-for <a href="coords.html#ObjectBoundingBox">bounding box calculations</a>
-and for calculation of <a href="masking.html#ClippingPaths">clipping paths</a>.
-If <a>'display'</a> is set to <span class="prop-value">none</span> on a
-<a>'tspan'</a>, <a>'tref'</a> or <a>'altGlyph'</a> element, then the
-text string is ignored for the purposes of text layout; however, if
-<a>'visibility'</a> is set to <span class="prop-value">hidden</span>,
-the text string is used for text layout (i.e., it takes up space)
-even though it is not rendered on the canvas. Regarding events, if
-<a>'display'</a> is set to <span class="prop-value">none</span>,
-the element receives no events; however, if <a>'visibility'</a>
-is set to <span class="prop-value">hidden</span>, the element
-might still receive events, depending on the value of property
-<a>'pointer-events'</a>. The geometry of a graphics element with
-<a>'display'</a> set to <span class="prop-value">none</span> is
-not included in <a href="coords.html#ObjectBoundingBox">bounding box</a>
-and <a href="masking.html#ClippingPaths">clipping paths</a>
-calculations; however, even if <a>'visibility'</a> is to
-<span class="prop-value">hidden</span>, the geometry of the graphics element
-still contributes to bounding box and clipping path calculations.</p>
