I am using X-Theme at our support site @ support.rvhobo.net. The problem is that there appears to be a conflict with X-Theme. I tried a plain page: http://support.rvhobo.net/submit-ticket/ and a page edited with Cornerstone, placing the shortcode in bot their "raw" and text components: http://support.rvhobo.net/support/. In the first case, you will see the buttons are messed up. In the second case, the control widths were overridden.
I tried creating new classes using your names (they show up in the "Raw" control in Cornerstone). I used both .classname and #idname with no luck.
I would rather have #2 working (Cornerstone) but would be OK with #1 (standard page).
Any help would be appreciated,
