Problems with the website

Good morning,
I’m experiencing a series of problems with the template.

1 – As regards the HOME, I am having problems with the photo on the page, I see it as blurry. I tried to modify the section with a CSS, but I still can’t modify it.
2 – I would also like to modify the socket section, as I would like to move a portion of text towards the right side of the screen, but I cannot move it. I tried with some code, but it doesn’t move where I say, I thought because the section in which I wrote is too small.
3 – Another problem encountered concerns the images present on the various pages. When I open the various pages they don’t appear extended, but first small and then they extend. I would like them to be directly extended.
4 – I would like to add the menu to HOME too, and have it visible immediately under the photo or in any case so that it overlaps with the photo. I don’t want anyone who comes to my site to be able to see the menu just by scrolling through the HOME.
5 – Another problem I encountered is that when I reduce the % of the screen the site doesn’t fit.
6 – another problem, when I move some menu items I can’t click on them and consequently I can’t view the pages. In the specific story, the problem concerns the PSORIASIS item and the THERAPIES item.

I attach an image proof for each number.
