You would not be able to use Showcase IDX or have an IDX that integrates the data in a way that appears native to Google building an HTML5 site. I’m a fan of HTML5 for many non-real estate applications, but to take advantage of modern IDX, you’ll need to use WordPress. There are some outdated IDXs that use subdomains or iFrames that you could use but you will run into a variety of issues. Watch this 3-minute video for a quick overview of what those are to see if that is still an avenue you want to consider.

Now, if you choose to build the site with WordPress, we work with shortcodes and you can customize a large amount via CSS. You can get much of the customization you’re looking for by choosing a super light weight theme or creating one yourself. That would allow you to use Showcase IDX and the WP infrastructure but have near full control of your design. We have many graphic designers that use DIVI too.

Thanks, David. Just checked out your site. Tons of things I love on it. Great work at making me feel like you’re the local expert and part of the community. Blog posts like “365 Phoenix Hikes” series and “How To Clean Windows in the Desert”, along with your podcast give real value for the 99% of time when someone is not buying or selling.
