I'm moving along well now, but still have a ton to learn. I've added a "code" element to a section on the CAHDental page. In that section, I've added a span, a link, and two images. With CSS, I've styled the images to act like a "rollover". I save the HTML and CSS without error and no syntax validations in the editor window. While I'm on the page, the rollover picture is there and works flawlessly. I save the editor code and save the "site" with the save button on the left.
I then can go to edit another page. When I come back to the dental page, my HTML, and thus my rollover, is gone! Oddly enough, the CSS is saved.
Here's my HTML code:
Any help you can provide is greatly appreciated. I've also enabled support access to the site.
PS: The rollover was found searching the wordpress support forum. I could only wish to be that smart.
