An issue was initially reported by a customer using an IE browser (specific version unknown). I was able to reproduce the problem on my Samsung Galaxy 3 mobile's Chrome browser. The CSS is not being applied to the page when accessing this link with two query strings:
Upon inspecting the source code, it can be seen that the necessary CSS files are being called and are accessible: iqRegional.css keywordsearchsearchform.css iqBIM.css
While one CSS file is linked absolutely, the other two are linked relatively. Despite this, none of the files load on my Samsung Galaxy 3 mobile's Chrome browser for this specific page.
However, after shortening the query string in the URL, the CSS loads without any issues.
