I have <div> block, that have some fixed width. Sidebars stretch until their width reach some value. Then block should stretch instead of sidebars. How can I implement this in CSS?

“Sidebars” are just <div>‘s margin (space).

Solution:

div
{
    /* Left and right margin stretch from zero to infinity */
    margin:0 auto;

    /* 2em is minimal side width */
    padding: 0 2em;

    /* Expected width */
    max-width: 640px;

    /* Minimal width */
    min-width: 320px;
}
