Tutorial - It's never to late to learn
Over the years, there has been an extreme development in web design - both in functionality and in availability.
Not too long ago, the number of people who knew how to make a web page was limited - making the information less available.
Now - you can find numerous guides and tutorials on the subject.
But the question is how to start:
If you are completely new to HTML and web design - you should try one of these sites, they are very basic and easy to understand.
If you have some knowledge, but want to learn how to make a professional web page - perhaps one of these sites can be of assistance:
Trying to read everything on these pages is an impossible task - you need some time to actually build your site - but they are very useful as references or guides.
Start with a simple webpage - do not try to build one great web page on your first try, it's better to build a few - learning as you go.
