This is quite a strange problem I'm experiencing. I've got a Wufoo form set up to load an external stylesheet. Wufoo is doing this properly and I can find the link tag and follow the href of that tag to the actual link and view the source of the stylesheet I've uploaded. So I know the stylesheet is indeed loading no problem (in fact, it's loading last), but not a single style is actually applied.
Right now I've even tried adding !important to my styles in an attempt to override the current styles. I don't see the styles loading into Firebug either.
Here's the link to the stylesheet.
The test I'm doing is in the latest version of Chrome to get the input and textarea tags to have a border-radius of 10px.
All that needed to happen was that I disable SSL for Wufoo because the protocol of my website isn't over secure HTTP. Apparently my stylesheet was being loaded, but not correctly implemented.
Here's more information on that from Wufoo.
By default, all accounts that are SSL enabled will have SSL forced upon every form. In some settings, mainly due to browser configuration, SSL is not desired. We can override SSL by slightly modifying the URL for a form.
