Our navigation column has disappeared, how should we solve it.

Create a collapsible column:

Use the navbar-toggle method that comes with the plug-in to operate

<button type="button"class="navbar-toggle"data-toggle="collapse" data-target="#navbar-collapse">
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
</button>

<span class="icon-bar"></span>

One statement represents one line, three statements represents three lines, the effect is as follows
