Positioning a div near bottom side of another div
提问by Roman
I have outer div and inner div. I need to place inner div at the bottom of the outer one.
我有外部 div 和内部 div。我需要将内部 div 放在外部 div 的底部。
Outer div is elastic (width: 70% for example). I also need to center inner block.
外部 div 是弹性的（例如宽度：70%）。我还需要将内部块居中。

You need a wrapping div for the bottom one, in order to center it.
您需要一个包装底部的 div，以便将其居中。
<style>
/* making it look like your nice illustration */
#outer { width: 300px; height: 200px; background: #f2f2cc; border: 1px solid #c0c0c0; }
#inner { width: 50px; height: 40px; background: #ff0080; border: 1px solid #800000; }
/* positioning the boxes correctly */
#outer { position: relative; }
#wrapper { position: absolute; bottom: 3px; width: 100%; }
#inner { margin: 0 auto; }
</style>
<div id="outer">
<div id="wrapper"><div id="inner"></div></div>
</div>

CSS3 Flexboxallows the bottom positioning very easily. Check the Flexbox support table
