White margins in mobile version

Hi there,

It turns out that when I view my website on a mobile device, white margins appear on the right and bottom sides, which produce a very unpleasant scrolling both horizontally and vertically where these white margins appear.

I would like to know if anyone knows how to make them disappear so that the mobile version is completely adjusted to the screen and can only scrolling along the actual content of the page.

I attach an image so you can see it and also the link to my website.

I also attach a video.
