css - 使垂直流向水平的按钮组干净利落

Question

我在一列中使用了普通的 bootstrap 3 按钮组，例如

<div class="col-sm-1">
  <div class="btn-group">
    <button class="btn btn-default"><span class="glyphicon glyphicon-home"></span></button>
    <button class="btn btn-default"><span class="glyphicon glyphicon-circle-arrow-left"></span></button>
    <button class="btn btn-default"><span class="glyphicon glyphicon-volume-down"></span></button>
    <button class="btn btn-default"><span class="glyphicon glyphicon-volume-up"></span></button>
    <button class="btn btn-default"><span class="glyphicon glyphicon-off"></span></button>
    <button class="btn btn-default"><span class="glyphicon glyphicon-zoom-out"></span></button>
    <button class="btn btn-default"><span class="glyphicon glyphicon-zoom-in"></span></button>
  </div>
</div>

当有空间时这是垂直的，但是当它下降到新行时它变成水平的。我唯一的问题是垂直时看起来有点奇怪。我试过使用 CSS 无济于事，有人有建议吗？我不介意让它完全正方形，所以水平/垂直相似，但我为此所做的努力没有奏效

如果完全方形的按钮对你来说没问题，像这样的东西应该可以工作:

CSS:

#group button:first-child, #group button:last-child {
    border-radius: 0;
}
#group button:first-child {
    margin-left: -1px;
}

HTML:

<div class="col-sm-1">
  <div id="group" class="btn-group">
    <button class="btn btn-default"><span class="glyphicon glyphicon-home"></span></button>
    <button class="btn btn-default"><span class="glyphicon glyphicon-circle-arrow-left"></span></button>
    <button class="btn btn-default"><span class="glyphicon glyphicon-volume-down"></span></button>
    <button class="btn btn-default"><span class="glyphicon glyphicon-volume-up"></span></button>
    <button class="btn btn-default"><span class="glyphicon glyphicon-off"></span></button>
    <button class="btn btn-default"><span class="glyphicon glyphicon-zoom-out"></span></button>
    <button class="btn btn-default"><span class="glyphicon glyphicon-zoom-in"></span></button>
  </div>
</div>
