设置响应式HTML背景
美好的一天，我有一个带有两个背景图片的简单网页。所以这是我的CSS
body{
background:
url('<?=base_url();?>/assets/header_bg.png')no-repeat ,
url('<?=base_url();?>/assets/footer_bg.png')no-repeat;
background-size: contain;
background-position: 100px -30px, 0px 98%;
-webkit-background-size: contain;
-moz-background-size: contain;
-o-background-size: contain;
}
这是结果（我只会采用顶部和页脚部分）
热门主页：
关于页面的顶部：
然后问题，家庭底部：
关于底部：
如您所见，about页面中的bg图像未满。对此有何解决方案？
顺便说一句，我正在使用codeigniter。这是我的整页

答案 0 :(得分：5)
您将以98％设置第二个背景位置。这意味着您将根据顶部中的98％设置其位置。在不同高度的页面上，背景的视觉位置在绝对像素上会略有不同。
您的页脚似乎高约40px，因此不是98％，而是将值设置为calc(100% - 40px)。
