/**
- * <H4>
- * 'background-position'
- * </H4>
- * <p/>
- * <EM>Value:</EM> [<percentage> | <length>]{1,2} | [top | center
- * | bottom] || [left | center | right]<BR>
- * <EM>Initial:</EM> 0% 0%<BR>
- * <EM>Applies to:</EM> block-level and replaced elements<BR>
- * <EM>Inherited:</EM> no<BR>
- * <EM>Percentage values:</EM> refer to the size of the element itself<BR>
- * <P> If a background image has been specified, the value of
- * 'background-position' specifies its initial position.
- * <P> With a value pair of '0% 0%', the upper left corner of the image is
- * placed in the upper left corner of the box that surrounds the content of
- * the element (i.e., not the box that surrounds the padding, border or
- * margin). A value pair of '100% 100%' places the lower right corner of the
- * image in the lower right corner of the element. With a value pair of '14%
- * 84%', the point 14% across and 84% down the image is to be placed at the
- * point 14% across and 84% down the element.
- * <P> With a value pair of '2cm 2cm', the upper left corner of the image is
- * placed 2cm to the right and 2cm below the upper left corner of the element.
- * <P> If only one percentage or length value is given, it sets the horizontal
- * position only, the vertical position will be 50%. If two values are given,
- * the horizontal position comes first. Combinations of length and percentage
- * values are allowed, e.g. '50% 2cm'. Negative positions are allowed.
- * <P> One can also use keyword values to indicate the position of the
- * background image. Keywords cannot be combined with percentage values, or
- * length values. The possible combinations of keywords and their
- * interpretations are as follows:
- * <p/>
- * <UL>
- * <LI>
- * 'top left' and 'left top' both mean the same as '0% 0%'.
- * <LI>
- * 'top', 'top center' and 'center top' mean the same as '50% 0%'.
- * <LI>
- * 'right top' and 'top right' mean the same as '100% 0%'.
- * <LI>
- * 'left', 'left center' and 'center left' mean the same as '0% 50%'.
- * <LI>
- * 'center' and 'center center' mean the same as '50% 50%'.
- * <LI>
- * 'right', 'right center' and 'center right' mean the same as '100% 50%'.
- * <LI>
- * 'bottom left' and 'left bottom' mean the same as '0% 100%'.
- * <LI>
- * 'bottom', 'bottom center' and 'center bottom' mean the same as
- * '50% 100%'.
- * <LI>
- * 'bottom right' and 'right bottom' mean the same as '100% 100%'.
- * </UL>
- * <p/>
- * examples:
- * <PRE>
- * BODY { background: url(banner.jpeg) right top } / * 100% 0% * /
- * BODY { background: url(banner.jpeg) top center } / * 50% 0% * /
- * BODY { background: url(banner.jpeg) center } / * 50% 50% * /
- * BODY { background: url(banner.jpeg) bottom } / * 50% 100% * /
- * </PRE>
- * <p/>
- * If the background image is fixed with regard to the canvas (see the
- * 'background-attachment' property above), the image is placed relative to
- * the canvas instead of the element. E.g.:
- * <PRE>
- * BODY {
- * background-image: url(logo.png);
- * background-attachment: fixed;
- * background-position: 100% 100%;
- * }
- * </PRE>
- * <p/>
- * In the example above, the image is placed in the lower right corner of the
- * canvas.
