Is your website ready for Internet Explorer 8? Tips to tell your webmaster.

It’s a shock to discover that your web forms aren’t submitting leads, or that your ecommerce site can’t take orders in a new version of a web browser. But believe me, these surprises happen. Any website developer or agency worth their salt will continually test that your website is working well across different browsers. Check that your web provider is up to speed.

To help, here are some excerpts from Microsoft’s tips on how to be compatible with IE 8 that you can forward along.

Developer Checklist:

For compatibility:

  1. Navigate to your website in Internet Explorer 8.
  2. If pages look different from how they did in Internet Explorer 7 or don’t work the same way, enable Compatibility View. See Compatibility for more information.
  3. If turning on Compatibility View makes your pages render and function as they do in Internet Explorer 7, then add the Emulate IE7 meta tag.
  4. Otherwise, verify that your User Agent String detection recognizes Internet Explorer 8 by using the procedure outlined in the Versioning and Internet Explorer Modes.
  5. If your pages are still broken, debug your Web site by using our testing tools.
