[Trisquel-users] Free website making

[vladimir . dorohin]

I've been interested in website making since I was about thirteen years old,  
but after a little practice my interests changed, and I started all over  
again one month ago - after more than five years. Now I'm working on the  
interactive internet-shop, where people could buy some ecologically safe  
homemade stuff, and I want to make it really convenient. That's why I've  
bought a book about HTML5, CSS3, JavaScript, PHP and CMS. Unfortunately,  
despite of the fact that the material in this book is well-described, there's  
nothing about using these web-languages for making free websites - and I mean  
freedom, not cost. Even examples used in this book have been made for  
Microsoft Windows operation systems!

Because of this, I want to ask: which internet-technologies and languages (or  
their versions) can I use freely without any licences and agreements? Which  
of them have "unexpected proprientary surprises"? I also know that there's  
something unclear in HTML5 because of the DRM support - can you explain it  
too (I've already read the FSF article)?

If you have some stories about your experience in this area, please, share  
them: it will be so interesting to read!
