align = "center" is no longer relevant, but what gave in replacement? How to align the page in the center? margin: 0 auto; does not give a result. You can margin: 0 (number) px; this is real only if you know the display resolution and the width of the page.
margin: 0 (display resolution - page width) px; But how to find out the display resolution and page width? And how to cram it into a margin (there you can enter only 1 number, not an expression).
I have everything in 1 big diva with main ID,
main{ position: absolute; margin: 0 10px; top: 0px; width: 1240px; height: 1600px; z-index: 1; text-align: left; }
display resolution - 1280x1024 page width - 1240 => so that the page was in my center (1280-1240) / 2 = 10 => margin: 0 10px;
