HomeWeb Front-endHTML TutorialCSS3原生支持div与浏览器等高等宽方法_html/css_WEB-ITnose

一般我们需要设置一个div与浏览器等高并等宽充满全屏,然后设置背景图片来达到一个高大上的排版效果。具体的例子看下面的图片演示:

随着鼠标的滚动,整个图片也滚上去了。

以前为了达到这样的等高效果,一般通过js来获取当前浏览器高度然后动态设置div的height,有时候还需要不断地检测浏览器resize事件来不断调整div的height。

其实CSS自带的两个单位vw与vh就能支持与浏览器等高等宽的效果,完全可以抛弃js了!
演示效果

html代码如下:

<!DOCTYPE html><html><head>    <meta charset="utf-8">    <meta http-equiv="X-UA-Compatible" content="IE=edge">    <title>全屏图片</title>    <link rel="stylesheet" href="http://cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css">    <style>        .fullbg {            position: relative;            width: 100vw;            height: 100vh;            background-position: center center;            background-size: cover;            background-repeat: no-repeat;        }        .inner-content {            position: absolute;            top: 50%;            left: 50%;            transform: translate(-50%, -50%);            color: #fff;        }    </style></head><body>    <div class="fullbg" style="background-image: url('http://s.dgtle.com/portal/201601/08/180115ol7n5o75zy7hm002.jpg?szhdl=imageview/2/w/1900');">        <div class="inner-content">            <h1 id="我就是这么屌">我就是这么屌</h1>        </div>    </div>    <div class="entry-content">        <p>            相信方今不再会有人质疑手机仅仅只是一个纯粹的通讯工具,随着移动社交应用日渐成为生活中不可缺少的工具,手机的照相功能表现甚至成为了衡量一部手机好坏的关键指标。在绝大部分的旗舰级手机新品发布会之中,我们经常可以看到各厂商们在介绍自家旗舰级机型拍照能力之时自吹自捧得无可匹敌,但我们深知在这些顶级水平的旗舰级手机当中,仍然需要使用真正的实力去决一胜负,而这正是本文的主要任务。        </p>        <p>            本文我们选择了四款旗舰机型,当中分别有索尼 Xperia Z5 Premium 、苹果 iPhone 6s Plus、 三星 Galaxy S6 Edge+、谷歌 Nexus 6P。        </p>    </div></body></html>

css核心代码如下

.fullbg {    position: relative;    width: 100vw;    height: 100vh;    background-position: center center;    background-size: cover;    background-repeat: no-repeat;}
