                        .header_content and .content should have the same margin: 0 XX% for the same media
                3 .flex_between (is placed at the center, as the grid of page, with: margin: 0 auto)
                        Set only the max-width as equal to the max-width of the .content_grid
    Give the #header the same padding as .page so that
    the width of its content follows the width of page content
