contrast all site in black

There’s a modal container with the id #elementor-popup-modal-6893 that is overlaying your site. The contrast tool gives this container a black background, as it does all containers, but since this container is on top of all content, it ends up obscuring your content.

If you add something like this to custom styles it should fix the issue for you:

#elementor-popup-modal-6893 { background: transparent !important }
