2016.1.41. Clear Floating Methodhttp://blog.csdn.net/clare504/article/details/39524215
To add an empty element using a pseudo-class. clearfix:after {content: "\0020";Display:block; height:0;Clear:both; }. clearfix {zoom:1; }"Clearfix" is the class name of the parent container, "Content:" 020 ";" is to place a white space character at the end of the parent container, "height:0;" Is let this this whitespace character not show out, "Display:block; Clear:both; " is to ensure that this whitespace character is a non-floating, independent block. However,: after the selector IE 6 is not supported, that is, the above code in IE 6 is not valid, what to do? we add a unique command for IE 6 "zoom:1;" All right, the purpose of this command is to activate the parent element's "haslayout" property so that the parent element has its own layout. IE 6 will read this command, and other browsers will ignore it directly.
