Web mockup and workable prototype (online cloud storage function)

We need a web (html+css+js) mockup and this is not only just design mockup but all the button and link should works (or looks like working) This is a single page web site which will provide online storage service This is a mockup include UI/UX implementation on HTML/CSS/JS * NO need to have server function. All the button/click could be “fake” via a simple javascript response * Should consider “common error handling” * Spec: 1. Please referece to [login to view URL] or googledrive ...However, DO NOT just copy the design from this site 2. upload file, download file, upload whole folder from/to your PC 3. delete file, tag file 4. create/delete sharable link 5. drag/drop (html5) upload file/folder 6. show folder’s contain in list or icon 7. preview image, doc, ppt. 8. sort list by name or created date or uploaded date * if you want to do this task, you need to read this spec carefully, to prove that, this is your secret code to tell me when we chat:) -> “SEPT30” * You can freely choose the color/background style * The delivery is a zip file with all your HTML/CSS/JS which could run in chrome/safari without server * Again. NO need to have server side function. all the functions are fake (mockup)
