I have converted most of the pages on the website from HTML to PHP. PHP will allow me to do some fancy things with the website. My main motivation was that I could create standard elements that individual pages can pull in. I am doing this with the pages header, so I only need to change one file rather than all of them.
While I was making the conversions, I standardized the look of the individual pages. When I created the pages, I used a slightly different approach each time. I now have a couple of templates to use. I made more variations in the standard than I had planned to, but I think that they were all justified.
