.clearfixをいつも忘れてしまうので、メモ。

/* clearfix
=========================================*/
.clearfix:after {
content: "."; display: block; height: 0; clear: both; visibility: hidden;
}
.clearfix { display: inline-block; }

/* Hides from IE-mac \*/
* html .clearfix { height: 1%; }
.clearfix { display: block; }
/* End hide from IE-mac */
/*=========================================*/
