What programming languages do you need to know to create a mobile friendly website?
One of the SEO trends of 2016 is to have a website with good user experience. In order to have a good user experience, you must have a mobile friendly website to give mobile users the best experience. My question is what programming languages do you need to know to create a mobile friendly website? I know that you will need CSS to style your website but as far as I know CSS itself won’t make the website mobile friendly.
Also, what is the difference between a responsive theme and a mobile theme? What are the benefits of the two?
