Can someone tell me how to develop a fast website without reduce any content of the website?

Answer 1

i think, to make static websites use JavaScript as beginner or be a wonderful web developer !!

Answer 2

definition of "fast website" is as generic as it can be.
what are your current bottlenecks?
too many Ayax calls?
too many page reloads?
big assets that take longer to load? (images of several mb, audio, video?)

i'm sure that once you'll identify the User eXperience bottlenecks, you'll be able to get rid of the problem.
