100%高度的背景图像:需要填充页面 [英] Background Image with 100% height: Need to fill page
问题描述
我有一个小的.png文件重复形成背景图片。我需要将页面的 body
高度设置为100%才能在我的内容包装器上使用min-height属性。但是,尝试将背景图像与 height:100%
结合使用会导致图像在滚动页面时被截断。看图片详细说明我的意思:
I have a small .png file that repeats to form a background image. I need to set the body
height of my page to 100% in order to use min-height property on my content wrapper. However, trying to use the background-image in conjunction with height:100%
results in the image getting cut off when the page is scrolled. See picture to elaborate what I mean:
背景最佳
但滚动时会被切断
Background on top But when scrolling it is cut off
如何在整个页面上重复显示背景图像,即使用户向下滚动?这是css:
How do I get the background image to repeat over the whole page, even after the user scrolls down? Here is the css:
body {
background-color:#9AAEBF;
overflow-y:scroll;
height:100%;
}
html:after {
background-image: url('http://www.example.com/img/background.png');
opacity:0.4;
content: "";
top: 0;
left: 0;
bottom: 0;
right: 0;
position: absolute;
z-index: -1;
}
感谢您的想法。
