If the bottom is more important: background-position: bottom;
background-position also allows percentage values: 0% 0%; by default.
The first value is the horizontal position and the second value is the
vertical. The top left corner is 0% 0%. The right bottom corner is
100% 100%. If you only specify one value, the other value will be 50%.
You should try background-position: 0% -10%;
