Welcome and thank you for the added content to Wipipedia.
It would be helpful if you kept to standard wiki editing commands rather than using HTML. HTML will mostly work but doesn't offer the versatility when, for example, a user changes the template (my eyes, for example, find the black background hard to deal with, so I use a template that has a white background).
If you are unfamiliar with wiki markup, you can see the Getting Started guide and for details, the information available from Help will provide most needs - while many of the articles from that page will take you to content on the much larger Wikipedia generic encyclopedia, the information is just as applicable here.
Once again, I thank you for the content you have added. It's always good to see another contributor here.
