仅在具有jquery或css的小屏幕上显示div

Question

我只想在小屏幕上显示此html代码。

<div id="NightDiv" class="w3-center" style="padding-top:20px"><i id="nightMode2" class="fa fa-moon-o fa-lightbulb-o w3-cursor-pointer w3-amazon"  aria-hidden="true"></i>
</div>

这是我尝试没有成功的事情：

$(document).ready(function() {

if ((screen.width>=1024) ) {
 $("#NightDiv").hide();
}
else {
 $("#NightDiv").show();

}
});

Answer 1

您不需要JavaScript。 使用CSS Media Query执行此操作，

/*Hide for larger screens*/
#NightDiv {
   display: none;
}

/*show for small screens */
@media screen and (max-width: 1023px) { /* I've given 1023px but you can change to proper width */
    #NightDiv {
        display: block;
    }
}

Answer 2

CSS媒体查询可以更好地处理此问题。 请参见以下示例：（展开代码段以隐藏div）

 //no javascript! 

 .w3-center { display: none; /* hide by default */ } @media(max-width:1024px){ .w3-center { display: block; /* or inline, or whichever style you prefer*/ } } 

 <link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.css" rel="stylesheet"/> <div id="NightDiv" class="w3-center" style="padding-top:20px"><i id="nightMode2" class="fa fa-moon-o fa-lightbulb-o w3-cursor-pointer w3-amazon" aria-hidden="true"></i> </div> 

Answer 3

<div id="NightDiv" class="w3-center" style="padding-top:20px">
    <i id="nightMode2" class="fa fa-moon-o fa-lightbulb-o w3-cursor-pointer w3-amazon"  aria-hidden="true"></i>
</div>

<style>
    #NightDiv{
        display: none;
    }
    @media only screen and (max-width:768px{
        #NightDiv{
            display: block;
        }
    }
</style>

Answer 4

 ShowDiv(); $(window).resize(function() { ShowDiv(); }); function ShowDiv(){ if (window.innerWidth>=1024 ) $("#NightDiv").hide(); else $("#NightDiv").show(); } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="NightDiv" class="w3-center" style="padding-top:20px;width:200px;height:100px;background-color:pink;"><i id="nightMode2" class="fa fa-moon-o fa-lightbulb-o w3-cursor-pointer w3-amazon" aria-hidden="true"></i> </div>

试试这个代码

 jQuery(document).ready(function () {
        jQuery('#NightDiv').hide();
        // Display the div on mobile resoultions
        if (jQuery(window).width() < 700) {
            jQuery('#NightDiv').show();
        }
    });
