Working as a solo developer (full stack) for my comp, their website's frontend is in shambles, UI,UX is just taken from what every last person liked from other's website in similar domain. Too much inline css and js unused styles and what not. Now I want to re-write the frontend and what to do it in such a way that this time makes changes will be easy and website becomes more responsive and better, I have little exp in responsive designing (I can get by for desktop screens) and I need help/guidance/resources in doing so
