What does this mean?
Do not link to an anchor on the page that does not exist. For example:
#content without a valid destination such as
<a href="#foo" onclick="$('.bar').toggle();">Click me</a> <div class="bar"> This is some content. </div>
In these cases, the anchor (
#foo) should point to the
id of the hidden element:
<a href="#foo" onclick="$('#foo').toggle();">Click me</a> <div id="foo"> This is some content. </div>
