This CSS will fix problems caused by Genesis Column Classes of uneven height. Just add a div with the class name of clear-line to your code. Then add this to your .css file.

Clear fix for Genesis Column Classes

/*
Clear fix for column classes
---------------------------------------------------------------------------------------------------- */
.clear-line:after {
  	content: ".";
	display: block;
	clear: both;
	visibility: hidden;
	line-height: 0;
	height: 0;
}
 
.clear-line {
	display: inline-block;
	width: 100%;
}
 
html[xmlns] .clear-line {
	display: block;
}
 
* html .clear-line {
	height: 1%;
}

Thanks heaps for this. It worked perfectly. Just had to add <div class="clear-line"></div> in my page text code in the WordPress editor after the code for the Genesis columns.

Puuuuuurfect !

Thanks, it works perfectly.
