.clearfix:after {
  content: '
/* http://www.yuiblog.com/blog/2010/09/27/clearfix-reloaded-overflowhidden-demystified */
.clearfix:before,
.clearfix:after {

display: block;
overflow: hidden;
visibility: hidden;
width: 0;
height: 0;
}
.clearfix:after {
clear: both;
}
/*
The following zoom:1 rule is specifically for IE6 + IE7.
Move to separate stylesheet if invalid CSS is a problem.
*/
.clearfix {
zoom: 1;
}
20'
; display: block; overflow: hidden; visibility: hidden; width: 0; height: 0; } .clearfix:after { clear: both; } /* The following zoom:1 rule is specifically for IE6 + IE7. Move to separate stylesheet if invalid CSS is a problem. */ .clearfix { zoom: 1; }

et voici le clearfix trouvé en Paul Irish HTML5 Boilerplate:

/* The Magnificent Clearfix: Updated to prevent margin-collapsing on child elements.
   j.mp/bestclearfix */

.clearfix:before, .clearfix:after {
    content: "
/* The Magnificent Clearfix: Updated to prevent margin-collapsing on child elements.
j.mp/bestclearfix */
.clearfix:before, .clearfix:after {
content: "\0020"; 
display: block; 
height: 0; 
overflow: hidden;
}
.clearfix:after { clear: both; }
/* Fix clearfix: blueprintcss.lighthouseapp.com/projects/15318/tickets/5-extra-margin-padding-bottom-of-page */
.clearfix { zoom: 1; }
20"
; display: block; height: 0; overflow: hidden; } .clearfix:after { clear: both; } /* Fix clearfix: blueprintcss.lighthouseapp.com/projects/15318/tickets/5-extra-margin-padding-bottom-of-page */ .clearfix { zoom: 1; }

Comme vous pouvez le voir, ils sont TRÈS similaire. Cependant, ils sont différents.

Quelqu'un a une idée dans ce?

Ce qui est mieux et pourquoi?
