Does anyone have experience with troubleshooting HTML5 CSS3 layouts across different browsers?
I recently created a website layout from scratch that looks perfect in Firefox 5, Safari 5.1 and Chrome 12 on Mac. However, when using tools like Adobe BrowserLab to test it, I noticed some issues such as the footer being misplaced, background repeating incorrectly, and submenus appearing unstyled.
Testing the site on Internet Explorer using browserlab or NetRenderer shows even more significant problems:
• In IE9, the radial background is missing, menus are disorganized, and content layout is completely broken.
• In IE8, sometimes the sidebar list takes up the entire space or displays as a black page.
• In IE7, the main content becomes unreadable among other issues.
I currently use two JavaScripts to address IE compatibility and HTML5 support, but they seem to be conflicting, leading to some pages displaying as blank.
I am concerned about the usability of my site for the 13% of visitors who use Internet Explorer. Any advice or assistance would be greatly appreciated as this issue is delaying the launch of my website.
