我正在尝试将复选框作为 Bootstrap 中的按钮居中。我尝试在周围的 div 和输入中使用“text-center”和“center-block”,但没有效果。 (您可以在示例中看到“text-center”和“center-block”在许多地方使用。)
HTML:
<div class="row grade-selection">
<div class="col-xs-1"></div>
<div class="col-xs-2 btn-group text-center" data-toggle="buttons">
<label class="btn btn-primary">
<input type="checkbox" autocomplete="off">K</label>
</div>
<div class="col-xs-2 btn-group" data-toggle="buttons">
<label class="btn btn-primary text-center">
<input type="checkbox" autocomplete="off">1</label>
</div>
<div class="col-xs-2 btn-group" data-toggle="buttons">
<label class="btn btn-primary">
<input class="text-center" type="checkbox" autocomplete="off">2</label>
</div>
<div class="col-xs-2 btn-group center-block" data-toggle="buttons">
<label class="btn btn-primary">
<input type="checkbox" autocomplete="off">3</label>
</div>
<div class="col-xs-2 btn-group" data-toggle="buttons">
<label class="btn btn-primary center-block">
<input type="checkbox" autocomplete="off">4</label>
</div>
<div class="col-xs-1"></div>
</div>
<div class="row grade-selection">
<div class="col-xs-1"></div>
<div class="col-xs-2 btn-group" data-toggle="buttons">
<label class="btn btn-primary">
<input class="center-block" type="checkbox" autocomplete="off">5</label>
</div>
<div class="col-xs-2 btn-group" data-toggle="buttons">
<label class="btn btn-primary active">
<input type="checkbox" checked autocomplete="off">6</label>
</div>
<div class="col-xs-2 btn-group" data-toggle="buttons">
<label class="btn btn-primary active">
<input type="checkbox" checked autocomplete="off">7</label>
</div>
<div class="col-xs-2 btn-group" data-toggle="buttons">
<label class="btn btn-primary">
<input type="checkbox" autocomplete="off">8</label>
</div>
<div class="col-xs-2 btn-group" data-toggle="buttons">
<label class="btn btn-primary">
<input type="checkbox" autocomplete="off">9</label>
</div>
<div class="col-xs-1"></div>
</div>
<div class="row grade-selection">
<div class="col-xs-3"></div>
<div class="col-xs-2 btn-group" data-toggle="buttons">
<label class="btn btn-primary">
<input type="checkbox" autocomplete="off">10</label>
</div>
<div class="col-xs-2 btn-group" data-toggle="buttons">
<label class="btn btn-primary">
<input type="checkbox" autocomplete="off">11</label>
</div>
<div class="col-xs-2 btn-group" data-toggle="buttons">
<label class="btn btn-primary">
<input type="checkbox" autocomplete="off">12</label>
</div>
<div class="col-xs-3"></div>
</div>
</div>
</div>
我创建了一个 fiddle ,并为其中一个 div 突出显示了不同颜色的背景,以便您可以看到缺乏居中的情况: https://jsfiddle.net/rovh1fcw/3/
感谢您的帮助!我确信我忽略了一些简单的事情。
最佳答案
Bootstrap 4 alpha 中的 text-center
类现在为 text-xs-center
。还要从列中删除 btn-group
,因为这会导致按钮显示为内联..
<div class="col-xs-2 text-xs-center" data-toggle="buttons">
<label class="btn btn-primary text-xs-center">
<input type="checkbox" autocomplete="off">1</label>
</div>
