Wordpress and coding work on a onepage website

Hello, the site is a onepage, it's fast work with a small budget to earn a little money.
The stains described below must be made on request.
From 1 to 4, present on the image attached here. And the others just described below.

1. When you click on the different parts of the menu, the slider and the description must be exactly in full screen and not with a space like now.

2. The slider from left to right is automatically in full screen, it is necessary to make sure that the slider stops at the description, so that the image does not remain cut off.

3. As shown on the image, the slider must be in full screen.

4. Make sure that the description and the reservation button are nice. I have an example on what to do this task.

5. Make some other parts of the site more compact so that they fit into a single page.

6. The site is a bit responsive, but you have to make it more responsive, I'll explain what to do.

7. Sometimes between the images of the slider, there is a white flash, it must be deleted.



Best regards.
