But for those of you who still remain in the dark and do not know much about this, let me start by giving you hints. For developers who love PHP, you might want to try using Symfony for development. This will open your doors to MVC and Rails programming and introduce you to AJAX too. But, if you are more adventurous and love more spice.. then why not try Ruby on Rails? I made mention these two because PHP and Rails seem to be the most common programming scripts used by developers. I myself use them.
CSS too is becoming popular with various Social Networking Sites, offering their subscribers with self customizable sites. Even the ordinary people who wanted their sites designed are now very much into CSS. It has eliminated the heavy use of tables for designing pages, and has given flexibility, style and fluidity with designing. With the use of CSS, even designers and programmers can separate their tasks ergo reducing much of development time and speeding up delivery of quality outputs.
Though CSS and AJAX prove to be much savoured technologies to date, remember still to keep your feet on the ground. Not everything must be done via these technologies to achieve the purpose of deploying your site. Each site has a different goal to achieve… so, one man's treasure can't be everybody's gold.
