I learned HTML in 1997. I haven't revisited it in all those years, focusing my efforts on server side languages that have been in use at the companies paying my salary (Cold Fusion, classic ASP, ASP.NET).
Now that HTML 5 is here, I've decided to rethink the paradigm and learn the standard way to code HTML and CSS.
Currently the site I manage is built to work in quirks mode. It makes extensive use of nested tables and has no doctype declaration. I've noticed that simply adding an html 5 doctype to the pages causes the page to not render correctly.
Can someone suggest a site or book or other material which will help me eliminate my reliance on tables and make the use of CSS make sense? I'm not looking to become a master overnight, but managing a site with thousands of pages means I better know what I'm doing before I dive into any redesign.
