CSS背景伸展到窗口底部？

Question

CSS背景伸展到窗口底部？

我正在帮助重新设计一个网站www.liveatsheastadium.com/test

我试图找出一种方法来获得透明背景(使用background:rgba属性)来拉伸页面的整个高度,无论分辨率如何.

我已经尝试将容器,html和body身高设置为100%并使用background:cover属性.

有关如何将背景扩展到页面底部的任何想法,无论窗口大小如何？

添加以下规则:

body, html{
    height:100%;
    margn:0;
    padding:0;
}

#container{
    min-height:100%;
}

但是,min-height并非所有浏览器都完全支持.如果您使用height它,如果容器中的内容高于页面,则会导致问题.要解决此问题,您可以创建一个100%x 100%div作为正文的副本,为它提供一个透明叠加的背景图像,并将其设置overflow为auto,因此它的行为类似于第二个正文标记.

HTML:

<body>
    <div id='body2'>
        //container
    </div>
</body>

CSS:

body{
    margin:0;
    padding:0;
    background:_image_;
}

#body2{
    margin:0;
    padding:0;
    width:100%;
    height:100%;
    overflow:auto;
    background:url(transparent.png) center top repeat-y;
}

transparent.png将是containerWidth x 1px,填充了您想要作为容器背景的rgba颜色.
