In the past, I have previewed all pages in as many browsers as I could. Age and experience have reduced this to just the lastest versions of Firefox and Chrome. If you are viewing these pages on IE, Edge, Opera, Safari, or something else and some feature looks weird to you, well, you are getting what you deserve.
The Cobalt Duck formerly used Tomcat Hosting from JavaPipe. As of 2019, it was switched to LAMP hosting from the same company.
I maintain a GIT repository for this site on BitBucket, however the repo for cobaltduck.info is private.
