Understanding of ../

1, see the introduction of css and js layui quick start before not quite understand

<link rel="stylesheet" href="../layui/css/layui.css">

<script src="../layui/layui.js"></script>

The original file and the folder where layui (../ behind the file name) at the same level directory

So write the name of the directory in the file and the contents of the file where it does not matter, but can be represented by the ../ directory structure relationship
