.container:after {

Please explain what is the effect of “content: “\0020”; property?
\0020inserts the Unicode code point U+0020, which is a space. So the code is equivalent tocontent: ' ';.content: xreplaces the content (= the displayed text) with the valuex.However, in the snippet you’ve posted, this content is made invisible anyway so you won’t actually see anything. The code is a clearfix implementation to re-float elements on the page.
