PSD to Responsive Making your design fluid It is very true that the world is moving towards portability. People won't be going to carry heavy devices to navigate your website. So, you need to reach to their mobile devices rather than bothering them to use desktops. Now, if there will be a same design for large and small screens, there will be much scrolling on small screen and all the conventions of user friendliness will move to the trash. The answer of all the constraints mentioned above is responsive web page. If you don't know on which screen resolution your web page is going to be opened, you need to have a page which can adjust it's layout with respect to the screen size. We take the design in PSD or ai format and convert it in a responsive html by using frameworks of responsive HTML. It makes all the elements change it's behavior on screen re size.
