Im still in the planning stage so any help much appreciated, Building site with Jquery mobile i want the user to be able to add/choose options, hit submit and a notification of there choices be sent instantly to recipient. Users will often be on a public wifi, or mobile data so i want the site to be as super light weight as possible. Am i going down the right path with Jquery mobile, and maybe using php or javascript for quick email updates?
better use html5 with normal javascript until you need some fancy effects or some solution which needs jquery only. It would make page light and jquery independant as well also minimal images thats important use background colors and flat design rather than bulky or gradient kinda stuff.
