<body>

<div class="contents"> Body </div>
<div class="footer">
<div class="footer-contents">
Some contents goes here
</div>
</div>
</body>
</html>
I see a gap between body and footer beca开发者_如何学编程use I have put 30px top margin for footer-contents div. Why can I put a div inside another with some top margin, Due to this margin the whole footer div is added margin of 30 px when you see it in browser, I can solve this by adding padding instead of margin, but I want to know what if I want to put a 700px wide div horizontally centered inside a full page 100% wide div, and also I want to add some margin the inner div.
Add some content other than the 'footer-contents' div to the 'footer' div. For example:
<div class='footer'>
<div class='footer-contents'>
Some contents goes here
</div>
</div>
In this case I get the margin applied correctly to the inner div.
