使div垂直居中

Question

我试图在bootstrap <header>中垂直对齐div中心，但它不起作用（请在投票之前访问JSFiddle链接！）：

<div style="display: table-cell; height: 50px; vertical-align: middle;">
    <button type="button" class="btn btn-default navbtn">
        <span class="glyphicon glyphicon-leaf"></span>
    </button>
    <button type="button" class="btn btn-default navbtn" >
        <span class="glyphicon glyphicon-cog"></span>
    </button>
    <div id="navbar-search">
        <button type="button" class="btn btn-default navbar-search-btn" >
            <span class="fa fa-search"></span>
        </button>
        <input type="search" class="navsearch" />
    </div>
</div>

当我删除navbar-search div按钮没问题。

注意：搜索容器有display:inline-block;并使其贴在顶部，我无法将其删除。

Answer 1

您需要将.navbar-btn添加到按钮以垂直居中。有关详细信息，请参阅Bootstrap Docs。

语义上如果它是导航，它应该在nav HTML5元素中。无论如何，你的列太宽了，正在按下图标（占据宽度100％的列不会留下任何空间）。

使用相当多的基础Bootstrap
