Header position

please post a link to your site to illustrate the problem.

the header elements have the same .column-half css class which is in the same style as your sidebar’s css class .column-sidebar;

by changing from ‘float: left; ‘ to ‘float: right;’ your are messing with the alignment.

try to change this back to as it was before (?):

.column-sidebar,
.column-half {
	margin-right: 3.8%;
	float: left;
	min-height: 1px;
}

then use more specific changes to move the sidebar; for instance by adding this line after it:

.column-sidebar { float: right; }

(not widely tested)

keep the change in this style, i.e. change to ‘float:left;’:

.column-content {
	margin-left: 3.8%;
	float: left;
	min-height: 1px;
}
