div高度100％

Question

I want to make a div 100% height, so basically the full screen. This, so that the background streches over the whole page. I don't want to add the background to the body, since i want it so that if i comment out the wrapper, the page is full width. (which works by the way)

So basically my question is: how can i make the wrapper-bg div 100% high.

Hope you guys can help me.

Answer 1

Try with .wrapper-bg {position:fixed; top: 0px; bottom:0px}

Answer 2

html,body{height: 100%}

Make sure that your parent element has height 100% and it should be positioned as relative. Try making it absolute. Your child div strech to parent height.

Answer 3

将主体高度设置为100％，因为div宽度或高度仅在将父代设置为某个值时才适用，例如，如果主体100％div高度为100％将起作用，则确定父代

Answer 4

Try this, should work as you have to make all parent elements 100%.

html, body {height: 100%}

.yourdiv {height: 100%}
