Create a Mobile Website

I want to create a Mobile-website with mostly content. The best way to describe the format is the app 'LactApp' A - First screen: 0/ inscription (name, username, email, terms acceptance) B - Main screen 1/ the higher part of the screen: logo and a small search 2/ the center part, 2a/ the screen split in 3 horizontally, with 3 photos defining each of them. Touch/swipe and the user will start navigating in an 'information tree'. 2b/ Intermidiate screens (branches) will have - a picture above and a 'button list' with text. Every time the user clicks on an item, he goes to the next level of the tree which can be an intermidiate screen or final leaf - top left, a small arrow to go back one level - top right, a small logo to go back to the home screen 2c/ Final 'leafs' will contain text and/or images. [v2.0 will include a social share button] 3/ in the lower part of the screen, a small horizontal part [fixed = appearing in all screens including 2a,2b,2c] with 3 buttons 3a/ 'Feedback' button. It will open a page/dialog with a small text, a textbox and a 'send' button. Users can send their opinion/feedback privately. The feedback will be registered, including the information of in which specific branch/leaf it was created and who wrote it 3b/ Profile: will include as optional fields: - date of birth, country, city, email - 3 descriptions with dropdown buttons (0,1,2,3,...up to 10) - dropdown buttons with a shortlist of text, where the user can add as many as needed. Once selected this will work as 'tags' to the profile. 3c/ 'Share': button will be shaded unless we are in the final leafs nodes and clicking it will only generate an action in those final leafs. It will open a page/dialog with a small text, a textbox and a 'share' button. The content shared will be displayed at the bottom of pages 2c along with the username. Backend: - allows the admin to modify the structure of the tree and the content of the leafs - allows to track per user / sessions, pages visited, time per page, comments [nothing fancy needed, i'm ok with having to pull this in SQL as long as the information is there] - allows to read the feedback from the users and answer them to their email
