CSS (Casding Style Sheets)

I know a little HTML but never really paid much attention to CSS (cascading style sheets). Now I know how important it can be in a website, it is a covenant way to change a page or a whole site with just a few tweaks.  It is a great tool to learn and I am looking forward to learning more about it. In my CSS page I used colors that an easy to the eyes, which helps in the page. I also used CSS to center the headings.  I am hoping that learning CSS in depth will help put creativity into pages I may create in the future
