背景 - HTML标记上的位置无效

Question

I'm following one tutorial on webdesign tutsplus, Final Page: http://webdesigntutsplus.s3.amazonaws.com/126_RibbonNavTutorial/code/demo_css_ribbon.html 我正在关注webdesign tutsplus的一个教程，最终页面： http ：//webdesigntutsplus.s3.amazonaws.com/126_RibbonNavTutorial/code/demo_css_ribbon.html

I've completed everything but one problem is coming in html styling, you can see I've included height:100% , but in original tutorial there was not that line, if I remove that line then it's collapsing, but in original tutorial it's perfect, why so? 我已经完成了一切，但是一个问题是html样式，你可以看到我已经包括高度：100％，但在原始教程中没有那条线，如果我删除那条线然后它崩溃了，但在原始教程中它是完美，为什么呢？

And also right now I've done height:100% then you can scroll at bottom and can see there's a margin left off at bottom, I want that image to stick at the very bottom of the page. 而且现在我已经完成了高度：100％然后你可以在底部滚动并且可以看到底部留有一个边距，我希望该图像粘在页面的最底部。
