<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>

<div class="container-fluid">
  <div class="row">
    <div class="col-md-4"><br><br><img src="images\smartphone.png" class="img-circle" alt="" width="243" height="241" align="middle"><br><h4  style="color:#1E7145" align="center">Smart Phone</h4></div>   
    <div class="col-md-4"><br><br><img src="images\oldphone.png" class="img-circle" alt="" width="243" height="241" align="middle"><br><h4 style="color:#1E7145" align="center">Basic Phone</h4></div>  
    <div class="col-md-4"><br><br><img src="images\tab.png" class="img-circle" alt="" width="243" height="241" align="middle"><br><h4 style="color:#1E7145" align="center">Tablet</h4></div>

缩略图未居中，文字居中，图片居左，有解决办法吗？

Answer 1

请使用 flex 尝试以下代码:

.imager div{
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;

}

<div class="container-fluid">
    <div class="row imager">
        <div class="col-md-4"><br><br><img src="images\smartphone.png" class="img-circle" alt="" width="243" height="241" align="middle"><br><h4  style="color:#1E7145" align="center">Smart Phone</h4></div>
        <div class="col-md-4"><br><br><img src="images\oldphone.png" class="img-circle" alt="" width="243" height="241" align="middle"><br><h4 style="color:#1E7145" align="center">Basic Phone</h4></div>
        <div class="col-md-4"><br><br><img src="img-circle" class="img-circle" alt="" width="243" height="241" align="middle"><br><h4 style="color:#1E7145" align="center">Tablet</h4></div>
    </div>
</div>
