    If a background-image is specified, the background-attachment CSS property determines whether that image's position is fixed within the viewport, or scrolls along with its containing block.


    background-attachment:  attachment[, attachment]*


    Is a keyword that can have one of the following values:
    • scroll, meaning that the background image will scroll within the viewport along with the block the image is contained within.
    • fixed, meaning that the background image will not scroll with its containing element, instead remaining stationary within the viewport.
    • local, meaning that the background image will not scroll with its containing element, but will scroll when the element's content scrolls: it is fixed regarding the element's content.



    body {
      background-image: url("images/cartooncat.png");
      background-attachment: fixed;

    Multiple background image support

    This property supports multiple background images. You can specify a different <attachment> for each background, separated by commas:

    body {
      background-image: url("img1.png"), url("img2.png");
      background-attachment: scroll, fixed;

    Each image is matched with the corresponding attachment type, from first specified to last.
