Question

这是我的第一个CSS编码，我有一个CSS代码，我从网站上调整它以适应我想做的事情，但是当我尝试更改下拉菜单的字体大小时，它没有'改变。

这是CSS代码：

<!-- CSS menu -->

我尝试在某些菜单中添加font-size：但没有改变。我还在这里查看了其他一些问题，但我无法使我的代码适应他们推荐的解决方案。

关于如何使蓝色方块中的文字字体更大的任何想法？

Answer 1

如果您要更改或添加font-size设置并且它们没有生效，那是因为您的样式被更具体的选择器覆盖，您更改了错误的选择器，或者＆＃＃39;你的CSS出错了。除非你broke the internet。我所要做的就是改变这两个：#cssmenu > ul > li > a和#cssmenu .has-sub ul li a。

更新以解决您编辑过的问题
要更改蓝色框中菜单项的字体大小，请更改：

#cssmenu .has-sub ul li a {
   font-size: 24px;
}

＆＃13;
