I have helped to build the site seen here: ihf.cornell.edu, from a basic WordPress site, to what it is now. I have had to break WordPress's CSS on multiple occasions in order to get the styling to look how it currently does, as I do not have WordPress Admin style editor privileges.. The reason as to why we still use WordPress as a platform, is the ease with which other members of the team, who do not have a strong knowledge of HTML and CSS, can alter the site if I am not available.
