我试图为768px屏幕显示btn-sm,但它一直向我显示btn-xs.
<div class="col-md-6 col-sm-6 col-xs-12 col-md-offset-3 col-sm-offset-3"> <button name="magnet" class="btn btn-success btn-sm btn-xs btn-lg"> <em class="glyphicon glyphicon-home"></em> Home </button> <button name="magnet" class="btn btn-danger btn-sm btn-xs"> <em class="glyphicon glyphicon-download"></em> Download </button> </div>
是否可以在不使用媒体查询的情况下完成此任务?
解决方法
您的按钮不会仅使用HTML进行神奇缩放.所以你有两个选择.
选项#1:重复
这个是最丑陋的,但它不符合您的需求,因为它不需要额外的媒体查询:
<div class="container"> <div class="col-md-6 col-sm-6 col-xs-12 col-md-offset-3 col-sm-offset-3"> <button name="magnet" class="btn btn-success btn-xs visible-xs"><em class="glyphicon glyphicon-home"></em> Home</button> <button name="magnet" class="btn btn-success btn-sm visible-sm"><em class="glyphicon glyphicon-home"></em> Home</button> <button name="magnet" class="btn btn-success btn-lg visible-md visible-lg"><em class="glyphicon glyphicon-home"></em> Home</button> <button name="magnet" class="btn btn-danger btn-xs visible-xs"><em class="glyphicon glyphicon-download"></em> Download</button> <button name="magnet" class="btn btn-danger btn-sm visible-sm"><em class="glyphicon glyphicon-download"></em> Download</button> <button name="magnet" class="btn btn-danger btn-lg visible-md visible-lg"><em class="glyphicon glyphicon-download"></em> Download</button> </div> </div>
选项#2:媒体查询
而且……最后.这是执行此操作的正确方法.
<div class="container"> <div class="col-md-6 col-sm-6 col-xs-12 col-md-offset-3 col-sm-offset-3"> <button name="magnet" class="btn btn-success btn-autosize"> <em class="glyphicon glyphicon-home"></em> Home </button> <button name="magnet" class="btn btn-danger btn-autosize"> <em class="glyphicon glyphicon-download"></em> Download </button> </div> </div>
.btn-autosize { padding: 1px 5px; font-size: 12px; line-height: 1.5; border-radius: 3px; } @media screen and (min-width: 768px) { .btn-autosize { padding: 5px 10px; font-size: 12px; line-height: 1.5; border-radius: 3px; } } @media screen and (min-width: 992px) { .btn-autosize { padding: 10px 16px; font-size: 18px; line-height: 1.33; border-radius: 6px; } }
