I am experience problems with inconsistent widths with content inside a column. Images and special headings have inconsistent widths based on browser window size. See the 6 main category images with special headings directly below here: http://ustriminc.com/ely
Please disregard this as I found a css solution to control special heading background:
.page-id-480 .av-special-heading-h2 {
background-color:#cc3333 !important;
padding-top:12px !important;
max-width: 355px !important;
margin: 0px auto !important;}
