我正在学习如何使用span,我在浏览器控制台进行了一些调试,但它们没有按照我在CSS类中定义的尺寸显示。我想知道我遗漏了什么,以便它们按照我给定的宽度和高度显示。谢谢。
HTML代码:
<div id="content">
<div class="forum-group">
<h2 class="header-2">General Discussion</h2>
<ul class="child-forums">
<li class="child-forum">
<a class="forum-link" href="#">
<span class="forum-icon"></span>
<span class="forum-details">
<span class="forum-title"></span>
<span class="forum-desc"></span>
</span>
</a>
