Clear code, kill errors - move back to the joomla roots.

Our homepage is www.josephineschober.de. As a template we used "foodworld" which is available online for free. Unfortunately, e.g. the "wrapper" id is coded not in joomla 3, which is the system of our homepage, but made with templates and overrides. So it is not possible to define e.g. the wrapper at joomla for all pages. The project now is: 1. Kill the unnessary code. Everything must be configurable at joomla, like it should be. 2. Set up everything what is necessary at joomla e.g. the modul "wrapper" 3. The id "kontakt", "top1", "top2" and "top3" must be placed on all pages, like it is now on the first page. 4. Check and clear "css" incl. bootstrap. So the page shall look good on mobile and desktop afterwards. There is always jus one code line. Not one codeline which is override by several other code lines in several other files. 5. Use and set up unique slideshow modules for every page. Kill the old code. (6) You can set up the template new too, if that saves time. But you have to keep the functionalities and the design of the page!
