Flask 修改当前页面链接的CSS属性

菜单是通过class="active"来修改状态的。

在Flask中的实现方式：

  All Posts
  Index
  Favorites

At the bottom of your base/layout template just add this

and the right elements will be set active.

EDIT: If you have a layout with elements in a list, like this:

  

    

        All Posts
    
    

        Index
    
    

        Favorites
    
  

use the **parent() **function to get the li element instead of the link.
