Responsive Design focuses on building websites that work on different devices. Your web designs should look good no matter what device your user is using. Responsive design requires changing how you build websites. There are many techniques for developing a responsive design. Tristan on Heliomblog suggests adopting a responsive web design process. This process emphasize content first. Web design works best when you have the content completed first. Then, use a mobile first strategy. It is easier to add on to a design for desktop users than it is to take things away for mobile.
No design and development process is perfect. You have to make changes as you discover what does and doesn’t work in your design. Design is solving problems, not just making things look pretty.
Make things & learn.
