I have been playing around with CSS to re-aquaint myself with it. It is much more intuitive and flexible than I remember. I am enjoying using blocks instead of tables. Even formatting for mobile has improved. It is a shame that so much of professional website development is now within CMS that essentially alleviates any need for HTML or CSS.
Still working with the proper position of the hovering text boxes. I changed the template so that there are only two columns. One for photos with blockquote quotations, and one for these change notes. It appears that I was not careful with the DIV tags here. Fixed! Also, I wonder if there is a good way to insert a variable for the DIV tag so I could use less code to innumerate the entries. There are some ideas online, I have to consider something that would be skinny enough for this site.
