html - 为什么这个 XHTML 无效？

Question

为什么这个 XHTML 无效？HTML:

<h2>earthquake warning <span>Posted 03/11/2009 at 2.05pm</span></h2>

CSS:

h2 {
font: bold 20px Arial, "Helvetica Neue", Helvetica, Geneva, sans-serif;
padding-bottom: 5px;
padding-top: 5px;
text-transform: uppercase;
}

h2 span {
font-weight: normal;
text-transform: none;
display: inline;
}

Answer 1

更多的是将h2放在span中。

<span class="warning">
                <h2>Bushfire warning <span>Posted 03/11/2009 at 2.05pm</span></h2>
                <p class="warning" />Dignissim elit quod dolore sollemnes iriure. Ut suscipit nunc laoreet lectorum facilisi. Consequat eodem consequn congue humanitatis. Vel in litterarum odio solissi. <a href="#">For more information click here.</a>

</span>

您不能将 h2 放在 span 标签内。尝试使用 div 代替:

<div class="warning">
                <h2>Bushfire warning <span>Posted 03/11/2009 at 2.05pm</span></h2>
                <p class="warning" />Dignissim elit quod dolore sollemnes iriure. Ut suscipit nunc laoreet lectorum facilisi. Consequat eodem consequn congue humanitatis. Vel in litterarum odio solissi. <a href="#">For more information click here.</a>

</div>
