    I have a very simple question! How would you exactly define a responsive site?

    What I mean is does it adjust the styling and text according to device’s resolution? Or do you decide the styling for each different resolution before hand?

    I am actually confused with this! Because some websites do not render properly on my phone, while they render properly on these tools. I am using Android’s Chrome browser on Motorola Razr!

      Basically Responsive Design is all about CSS Media Query. Were you have to write different CSS for Different sceensize resolution you can take the example of our website CSS for inspiration.

      Regarding your question both the things are same yes it should adjust the styling and text according to device’s resolution with CSS media query you can decide the styling of your website for each screen size.

      I hope this will solve your confusion.

        My question would be which would you suggest? I ask this question because nowadays there are Android phones from multiple manufacturers coming up with variety of screen sizes and resolution.

          Akshat i prefer to use media query but you can build complete Liquid base website which fits to every resolution. But according to me you should use CSS media query and target the different browser sizes as per your wish.
