As stated upfront, we design valid, standards-compliant themes with HTML5/CSS3.
We even pass Internet Explorer’s modern quality checks:

Our themes are not built nor tested for out-dated web browsers.
We do understand the dilemma of some companies being stuck on archaic systems due to the costs of upgrading.
If StartupPro is not suitable for your specific project, no worries. Please just confirm and we’d be happy to issue a refund.
