Our website is functioning perfectly with a white background on all modern browsers such as IE9-11, Chrome, Firefox, Safari, and others. However, there seems to be an issue with IE 8 where it displays a transparent background instead of the correct white one. This problem only occurs on the news page, leading me to suspect that it might be related to SharePoint's outdated tables-based layout structure (which I personally dislike). You can view the problematic page at this URL.
I would greatly appreciate any assistance you can offer in resolving this issue. Thank you in advance!
