响应式导航菜单的字体大小调整问题

时间：2016-08-31 01:57:23

标签： html css responsive-design font-size responsive

我创建了一个自适应导航菜单，但有些标题是较长的单词，因此当屏幕尺寸缩小时，它们会变得褶皱或重叠。是否有一种简单的方法可以使我的字体大小响应，而无需为每个字体断点进行多次媒体查询？谢谢！

添加媒体查询。

例如，取决于您想要的屏幕尺寸。

<style>
@media (max-width: 600px) {
  #nav {
    font-size: 16px;
  }
}
</style>

我可以看到你没有在网站上链接Bootstrap，所以我建议如果你正在使用响应式的东西来使用它，因为它会使调整大小变得容易。

看看这个：http://getbootstrap.com/getting-started/ 如果您打开页面并调整窗口大小，那么＆＃34;入门＆＃34;标题会随着它变小而缩小，这正是你正在寻找的。

所以只需抓住上述网站的框架，它就可以让您的网站更好地运作，反应灵敏。 Bootstrap为你努力工作！

@Citlalipop就个人而言，我会将您的移动菜单的快照点设为925px而不是640，因为您仍然会遇到问题＆＃34;学校办公室＆＃34;走2行。
