The Breakpoints and Picture modules (that will be part of Drupal 8 core!), in combination with a responsive theme (like Omega) are powerful tools to create a truly responsive site. In this post, I will provide you with the basic steps to create a responsive site using these tools.
It took a while but I finally got my own site converted to Drupal . I been working with Drupal for one and a half years now at Attiks and am enjoying myself tremendously. Drupal is a CMS that offers endless possibilities and has a very helpful and great community. It is free and open source. Many large sites are built on Drupal. Most can be found at buytaert.net , the site of Dries Buytaert, the developer of Drupal.
