When creating a header and adding new elements to a container, the elements appear to the left and I have to play with the margins to make it fit properly. If I add a second element below element 1, it seems to depend on the one above and it is very difficult to put them when I want. Is there any way to center them with just one click? Also, after palying with the margins and managing to accomodate the PC version if I check the laptop, ipad and phone versions the elements go all over the place. Is it not possible to just keep them center in all versions? Thank you.
