I thought I had a little problem. Just found out that I have a big one!
My main pages have popups that are sections of full pages.
I have just redesigned the pages and find that the new pages, that open properly in all modern browsers, are a big mess in Edge. The old pages open without those problems.
So, my question is “what has caused the difference”?
I’ve looked, and looked and cannot understand what is causing this.
Take an old page, press any of the “Look inside” bottons in the central column
Something in the new css is upsetting Edge. Both stylesheets work fine in all other browsers including IE8 - IE11
I disabled the popups in this page, except for the bottom 3 for testing purposes. One of these still has the old format, just like the Sydney page, yet, it, also, misbehaves. Maybe this is the best place to start. Why does the same page display differently?
