DW8 - will it be useable with Windows Edge? DW will no longer opeate

After re-reading this a few times, it seems DW 8 is not able to launch MS Edge from Preview-in-Browser.  Is that the problem you're having?  

I vaguely remember an issue when MS Edge first came out.  But it's been so long, I don't remember what the workaround was. 

Try opening your local file directly from MS Edge instead of DW8 preview.  Or better yet, get Firefox and Chrome and add them to the DW Edit Browser list.

I don't see anything in the code that would cause the site to turn gray as you describe and tried to load it up in a few browsers and were not able to replicate the issue.  Edge itself is based on chrome so running in any of those browsers should result in your issue.  As long as DW8 works, you should be able to make updates to the homepage as you describe.

Being that this is for a school, I would even consider reaching out and seeing if they would hand it to students to help clean up the code for you as a project or offer to help you get things into a better place for you and edit it for you.  It would be a good project for them and give you the help you need without the costs of hiring a developer.

If DW8 (from 2005) stopped working for you, replace it with a free or low-cost editor that understands modern HTML5 code.

Well, the site is showing it's age, naturally.  And MS Edge is a bleeding edge web browser that doesn't understand deprecated code.  It's like trying to put unleaded gas into a Tesla.  🙂
