hi Stert, there are several ways of doing this, here are two.
the first positions a specific <div> centrally across the page and gives a uniform layout.
right:10%; /*width is implied no need to set */
/*IE ignores 'right' so use width as well */
the second example uses margin to ensure that a class of <div>s is positioned at least 100 pixels away from any other element. this gives a more organic layout.
a sketch pad and pencil are useful tools when converting from table to div
. Dont be scared to experiment with position, top, left,bottom, right, width, height, margin etc
