In today’s world, any website that holds a fixed layout is not a perfect website. The site that holds a fluid gird system will automatically scale down to the screen size of any device that is used for accessing the website.
The site crafted with a responsive design will give an amazing browsing experience for the internet users. Based on the CMS that site users utilize for their website, there are different plugins that can add responsiveness to the website.
Even Frameworks like Skeleton, Foundation and Less will effectively turn your website with fixed layout into a responsive one.
