Positioning is accomplished via calculating absolute x,y coordinates from a reference element (i.e. you position an element in relation to a reference element, rather than the page).
The positioning library has two functions that provide x,y coordinates.
-
getPosition(positionedElement, referenceElement, config)- applies no margin or offset
-
getPositionWithArrow(positionedElement, referenceElement, config)- applies predefined margin and offset values based on redline specifications
Three options are available:
The position option defines the general location of the positioned element in relation to the relative element. The x,y coordinates of the positioned element can be fine tuned using the margin and offset options.
(starting from top left and going clockwise)
| Position | Location | Alignment |
|---|---|---|
top-start |
above and to the left | align left edges |
top-left |
above and to the left | align right edge with relative center |
top |
above centered | horizontally align centers |
top-right |
above and to the right | align left edge with relative center |
top-end |
above and to the right | align right edges |
right-start |
right and higher | align top edges |
right-top |
right and higher | align bottom edge with relative center |
right |
right centered | vertically align centers |
right-bottom |
right and lower | align top edge with relative center |

Offset is the distance in pixels toward the main axis. Use this option to shift the positioned element along the cross-axis.
Margin is the space in pixels, along the main axis, between the reference element and the positioned element.
