Centering text on mobile device

Hello, the text is only centred horizontally, even on desktops. It looks like it’s centred vertically, but it technically isn’t. That is because the slider height is higher than the monitor height, so you need to add a bunch of more pixels to the top borders of all your elements

Hello.
What kind of elements do you mean?

With elements I mean all your layers such as texts, images and videos
