Hi everyone, I am just getting into building my first website. So far I have been doing courses at codeacademy and I'm fairly comfortable that I can handle the HTML and CSS side of things. The website will allow users to login with a shared login for their particular group, upload an image, add what will more or less be stamps to the image and then save it for others to view. The only part I really need advice for at this stage is how to code for the stamp applicator. It needs to work on smartphones and tablets probably even more so than on desktops. So my questions are: 1. will it be easier to code 2 separate pages, one for mobile and one for desktop and have the correct one load for the device rather than trying to rearrange all the elements with CSS? 2. What language do I need to learn to code the stamp applicator? Given that it must work on phones and tablets? Thanks in advance for your time and help!
