Design /Theme

Hello, :)

If there is perhaps Tutorial videos or instructions, around the design for a well-chosen Theme
to adapt or has somebody collected there already experiences?

In general to the design / construction of contents I have a few questions:

1. I would hide with pleasure the standard menu strip in Drupal or according to the pattern
   Frontend / Baking split. External people thereby have to go by embedded ones
   Graphics on the sides can navigate and internal roles, like the Admin, so to speak
   by menu strip can steer. Is this possible perhaps or does have somebody a few tips?
2. Can pictures / article / videos be shown variably on the side? This
   also side by side can be placed and not like in the standard design
   together?
3. Can the size of an inserted video be adapted perhaps by hand? E. G. , one
   Youtube video or own video on the left beside text stands and extends not completely?
   Or the video can be worked on In general?
4. Does the possibility exist to integrate clickable graphics? So I have a picture and
   in it, e. g. , three areas (pixel / vectors), by click are on another
   internal side expel. So in the kind:
1. File: Hauptseite. png|750px
   rect 33 33 957 175 [[enterprise processes]]
   rect 997 33 1923 175 [[IT systems]]
   rect 33 217 1923 359 [[practise examples]]
   desc none
5. Are the Themes of Drupal also usable for Thunder? I had some
   tried out, however, the whole side or at least parts mostly seemed good of it
   shifted / damaged

Thanks :)
