答案 9 :(得分:0)
基于现在基于Flex的Bootstrap 4,您可以在Bootstrap align-items-center
上使用row
实用程序来垂直居中显示行的内容。
例如:
<div class="container">
<div class="row align-items-center">
<div class="col-4">
<img alt="img" src="http://asianmeditour.com/assets/images/post/1542457653tourism.jpg" class="img-fluid">
</div>
<div class="col-8">
Text vertically centred!
</div>
</div>
</div>
