<dd>
是的,a包含 a是有效的<ul>
。根据HTML 规范,<dd>
元素应该包含流内容。无序列表被视为流内容。
但是,如果示例中的每个项目都是前面术语的替代描述<dt>
,则不应将它们标记在无序列表中,而应使用一系列<dd>
元素进行标记。
例如,以下内容是有效的 HTML,但在语义上不正确- 因为它意味着整个列表是该术语的单一描述。
<dl>
<dt>Firefox</dt>
<dd>
<ul>
<li>A free, open source, cross-platform, graphical web browser developed by the Mozilla Corporation and hundreds of volunteers.</li>
<li>The Red Panda also known as the Lesser Panda, Wah, Bear Cat or Firefox, is a mostly herbivorous mammal, slightly larger than a domestic cat (60 cm long).</li>
</ul>
</dd>
</dl>
标记此内容的有效且语义正确的方法是:
<dl>
<dt>Firefox</dt>
<dd>A free, open source, cross-platform, graphical web browser developed by the Mozilla Corporation and hundreds of volunteers.</dd>
<dd>The Red Panda also known as the Lesser Panda, Wah, Bear Cat or Firefox, is a mostly herbivorous mammal, slightly larger than a domestic cat (60 cm long).</dd>
</dl>
