我想将轮播控件水平居中对齐，如下图所示：

这是我的轮播 html 代码

<div class="carousel-inner">

<div class="item active">
    <div class="row">
        <div class="col-md-7">
            <h3><button type="button" class="btn btn-default btn-sm"><span class="glyphicon glyphicon-list"></span></button>Lorel Ipsum</h3>

<div class="item">
    <div class="row">
        <div class="col-md-7">
            <h3><button type="button" class="btn btn-default btn-sm"><span class="glyphicon glyphicon-list"></span></button>Lorel Ipsum 2</h3>

    </div>
</div>

</div>
<a class="left carousel-control" href="#myCarousel" data-slide="prev">
  <button type="button" class="btn btn-default">Prev</button>
</a>

Answer 1

在外层div上添加这个类

.centerAlign{
    width: 400px; //some width you want
    position: relative;
    margin: 0px auto; //to align in center
    display: table;
}
