html - 将 Font Awesome 图标与文本对齐

Question

根据下图，这些设置在同一行，但我需要以图标为中心的文本，而不是底部。我在这里做错了什么？

我的代码:

<div class="alertBtns">
    <button class="naviaBtn naviaBlue" ng-show="ppt.Globals.hasDebitCard" ng-click="alertShow = (alertShow == 2 ? -1 : 2)"><i class="fa fa-exclamation-circle fa-2x" ng-show="ppt.Swipes.length>0"></i>outstanding swipes</button>
    <button class="naviaBtn naviaBlue" ng-click="showAlerts();"><i class="fa fa-exclamation-circle fa-2x" ng-show="isNotRead"></i>recent denials</button>                    
    <button class="naviaBtn naviaBlue" ng-click="alertShow = (alertShow == 4 ? -1 : 4)"><i class="fa fa-exclamation-circle fa-2x" ng-show="dateAlert"></i>upcoming dates</button>
</div>

Answer 1

在 div 内的 i 元素上使用 vertical-align:middle;。

div.alertBtns i{
  vertical-align:middle;  
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.1/css/font-awesome.min.css">

<div class="alertBtns">
    <button class="naviaBtn naviaBlue" ng-show="ppt.Globals.hasDebitCard" ng-click="alertShow = (alertShow == 2 ? -1 : 2)"><i class="fa fa-exclamation-circle fa-2x" ng-show="ppt.Swipes.length>0"></i>outstanding swipes</button>
    <button class="naviaBtn naviaBlue" ng-click="showAlerts();"><i class="fa fa-exclamation-circle fa-2x" ng-show="isNotRead"></i>recent denials</button>                    
    <button class="naviaBtn naviaBlue" ng-click="alertShow = (alertShow == 4 ? -1 : 4)"><i class="fa fa-exclamation-circle fa-2x" ng-show="dateAlert"></i>upcoming dates</button>
</div>
