The visual difference effect will be used when making a web page It has a very cool effect. Today we are going to talk about how to present dynamic visual difference

The production method first requires a visual difference plug-in

The plug-in I use is a relatively popular visual difference plug-in

    <link rel="stylesheet" type="text/css" href="css/reset.css" />
    <link rel="stylesheet" type="text/css" href="css/default.css">
    <link rel="stylesheet" type="text/css" href="css/style.css" />

Import these three css After file, you can modify the picture in style

Just modify the picture to the specified gif

Introduced below Use the plug-in method

        <div id="bei1">
            <img src="img/pubu1.gif"/>
        </div>
        <div id="bei2">
            <img src="img/pubu2.gif"/>
        </div>

Choose a gif

Use PS to simply crop a large gif image, and cut out two sides according to the proportion

    

#bei1{
    position: fixed;    //首先进行定位,相对浏览器定位,定在一左一右
    left: 0px;    //通过调整左右距离定在屏幕左右
    z-index: -1;    //调整z-index使其置入最底层
    width: 13%;    //合理调整宽度,使图片高度超过目前市面上绝大多数的屏幕高度
    img{
        width: 100%;    //改变图片宽度为100%
        min-height: 1080px;    //这里是为了防止高度不足,设定的最小高度
    }
}
#bei2{
    position: fixed;
    right: 0px;
    z-index: -1;
    width: 13%;
    img{
        width: 100%;
        min-height: 1080px;
    }
}

Display the main content in the center of the screen and cover the edges

#zuopinx{
    width: 80%;    //主要内容宽度
    background-color: #EEEEEE;
    position: relative;
    margin: 0 auto;    //居中
    margin-top: 80px;
    z-index: 15;
    padding-top: 40px;
