我在这里收到一个 w3c 验证错误
The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.
One possible cause for this message is that you have attempted to put a block-level element (such as "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").
这是我的源代码
<ul class="link">
<li><a href="" class="selected"><span>1<div class="clr"> </div><label>Vul Postcode in </label></span></a></li>
<li><a href=""><span>2<div class="clr"> </div><label>Restaurants </label></span></a></li>
<li><a href=""><span>3<div class="clr"> </div><label>Menukaart</label></span></a></li>
<li><a href=""><span>4<div class="clr"> </div><label>Afrekenen</label></span></a></li>
</ul>
请帮我找出问题,
谢谢
