Question

我试图隐藏一个模式，不会出现在手机和平板电脑上。

在bootstrap中，我正在使用hidden-md-down并且它正在工作，但它不再工作了，我无法改变任何事情：

＆＃13;

$(function(){
  $('##myModal').modal('show');
});

＆＃13;

<div class="ie-only" style="overflow-y:hidden;">
        	<div class="modal fade in hidden-md-down" id="myModal" aria-hidden="false">
            	<div class="modal-dialog modal-md custom-height-modal">
                	<div class="modal-content">
                    	        	<div class="modal-header topGrad" 
                        	<button type="button" class="close" data-dismiss="modal">x</button>
                            <h2 class="modal-header" style=""filter: alpha(opacity=200);">Outdated Browser Detected</h2><p>Our website has detected that you are using an outdated browser.

hidden-md-down类仅存在于Bootstrap 4中。

隐藏的md-down无效
