我以前没有遇到过这种情况,我很难找到解决方案。当在bootstrap中有一个等于medium的列时,如下所示:
<h1 class="text-center">Hello, world!</h1>
<div class="container">
<div class="row">
<div class="col-md-12 text-center">
<h1>vicki williams</h1>
</div>
</div>
</div>
文本对齐工作正常:
但是当使列值等于特小值时,就像这样:
<div class="container">
<div class="row">
<div class="col-xs-12 text-center">
<h1>vicki williams</h1>
</div>
</div>
</div>
然后文本对齐不再工作:
是否有一些我没有理解的引导概念,或者这实际上是一个错误,就像我认为的那样。我从来没有这个问题,因为我的文本总是在过去与xs对齐。任何帮助都将不胜感激。 这是我的完整代码:
