Do you know where I can learn about (X)HTML standards? I would like to understand them.
Best place to start is the sticky threads at the top of this forum, especially the "HTML vs XHTML" one.
Other than that, the first few links of a web search should do the trick.
Sitepoint have a number of good quality books if you want to learn HTML
If you want to learn about the standards, check out W3C (not W3C schools)
Thank you! I appreciate it.
