【问题描述】:
我正在尝试使用两个浮动的 div 将我的页面分成两个“列”。容器宽度为 900px,左列应为 400px,右列应为 500px。
我的问题是第一个 div 中的文本会出现(尽管占据了整个 900 像素),但 div 本身没有显示存在的迹象,即使我应用了边框或背景颜色。右侧的 div 也是如此。
HTML:
<div id="container">
<div id="leftpanel">
<h1>Left Panel Title Here</h1>
<p>Summary text goes underneath to draw attention to the
video on the right</p>
</div>
<div id="rightpanel">
<p>123 123</p>
</div>
<div id="content"><p>text to expand page</p>
</div>
<div id="columna">
</div>
<div id="columnb"></div>
<div id="footer">
</div>

【问题讨论】:
-
你有一个未关闭的@media query '@media screen and (max-width: 768px) {'需要在#leftpanel之前关闭。

谢谢吉姆!你让我头疼了

作为建议,请尝试将您的代码制成表格...与其他 css 相比,此 css 很小...始终将您的代码制成表格:-D 祝您好运!!
