Slideshow as full page background

Hello,

i created a slideshow as full page background, but the alignment don't work.

If i use the alignment 'bottom left' then the picture should started on left side. But the picture is aligned in the center. The element style contains margin-left.

Here the code:
Whats wrong?

All websites have a background slideshow. I do not like the behavior when changing the browser size, as parts of the image are trimmed unnecessarily. On the start page you can see this when resizing well. In the smartphone view, too much is removed at the top and bottom. The picture zooms out, why?

Unfortunately, the alignment does not work correctly. Alignment from the left makes no difference to the right orientation. That does not seem to work correctly. The best setting is top right and top center.

if I use this code, the alignment and the resize are okay
Can I correct this with CSS for the slideshow?

Hi
the slideshow does not use a background image, this is positioned by javascript. I have to work on this request. I will let you know
