html - 输入右侧的样式 Font Awesome 图标

Question

很难将此图标强制放在输入框的右侧而不是放在下方。更改了 col 号，放入 div 等。但什么也没有。这是现在的样子:

我的代码是(示例不显示结束表单标记):

    <form class="pptReg" role="form" name="pptReg" novalidate>
        <h1 style="padding-top: 60px; color: #ab2328;">Participant Information</h1>
        <div class="form-group col-md-3 naviaInp" style="padding-top: 30px;">
            <label for="empCode">Employer Code</label>
            <input type="text" name="empCode" class="form-control" id="empCode" data-ng-model="pptregistration.coCode" ng-required="true" maxlength="3" autofocus ng-blur="getEmpIdType(true);">
            <a class="questionIcon" href="#"><i class="fa fa-question-circle col-md-2 fa-2x" style="float: right;"></i></a>
            <div ng-show="(pptReg.$submitted || pptReg.empCode.$touched) && pptReg.empCode.$error.required">
                <p class="claimError"><i class="fa fa-exclamation-circle"></i><span>This is a required field.</span></p>
            </div>
            <div ng-show="(pptReg.$submitted || pptReg.empCode.$touched) && empIdType == ''">
                <p class="claimError"><i class="fa fa-exclamation-circle"></i><span>The Employer Code is invalid.</span></p>
            </div>
        </div>

这只是一个很棒的字体图标，我正试图将其添加到那里输入的右侧。我正在使用 Bootstrap 3 进行布局。

想法或建议(我自己脑子里想过很多!)？

非常感谢。

首先，您需要限制输入框的宽度，以便旁边有足够的空间放置图标。然后，您需要将输入和图标设置为 display:inline-block; 同时，从图标中删除不必要的 col-md-2 类。最后，将 vertical-align:middle; 添加到图标，使其与输入垂直对齐。

HTML:

<form class="pptReg" role="form" name="pptReg" novalidate="">
    <h1 style="padding-top: 60px; color: #ab2328;">Participant Information</h1>
    <div class="form-group col-md-3 naviaInp" style="padding-top: 30px;">
        <label for="empCode">Employer Code</label>
        <input type="text" name="empCode" class="form-control" id="empCode" data-ng-model="pptregistration.coCode" ng-required="true" maxlength="3" autofocus="" ng-blur="getEmpIdType(true);">
        <a class="questionIcon" href="#"><i class="fa fa-question-circle col-md-2 fa-2x"></i></a>
        <div ng-show="(pptReg.$submitted || pptReg.empCode.$touched) &amp;&amp; pptReg.empCode.$error.required">
            <p class="claimError"><i class="fa fa-exclamation-circle"></i><span>This is a required field.</span></p>
        </div>
        <div ng-show="(pptReg.$submitted || pptReg.empCode.$touched) &amp;&amp; empIdType == ''">
            <p class="claimError"><i class="fa fa-exclamation-circle"></i><span>The Employer Code is invalid.</span></p>
        </div>
    </div>
</form>

CSS:

.form-control {
  display:inline-block;
  width:90%;
}
a.questionIcon {
  display:inline-block;
  vertical-align:middle;
}
