I think the auto sizing is working – it looks like it sets the height to stop at the bottom of the page as defined by other elements on the page (each page height on the site is variable based on content). In this case the other content is minimal and so the page ends up short. I need to force this to be a set height or at least a minimum height.
I am using the iframe to view some GIS mapping. It is a WordPress site (still a work in progress) for a small association. In the meantime, I found another that allowed me to enter the “Height=…” code. It’s called easy-iframe-loader.1.3.1. If you have a chance to look at it, I’d be interested in knowing the differences and advantages.
Thanks for your help,
Bob
