HTMLImageElement: y property
The read-only HTMLImageElement property
y indicates the y-coordinate of the
<img> element's top border edge relative to the root element's
origin.
The x and y properties are only valid
for an image if its display property has the computed value
table-column or table-column-group. In other words: it has
either of those values set explicitly on it, or it has inherited it from a containing
element, or by being located within a column described by either
<col> or <colgroup>.
Value
An integer value indicating the distance in pixels from the top edge of the element's
nearest root element to the top edge of the <img> element's border
box. The nearest root element is the outermost <html> element that
contains the image. If the image is in an <iframe>, its
y is relative to that frame.
In the diagram below, the top border edge is the top edge of the blue padding area. So
the value returned by y would be the distance from that point to the top
edge of the content area.
Note:
The y property is only valid if the computed
value of the image's display property is either
table-column or table-column-group; in other words,
either of those are set directly on the <img> or they're
inherited from a containing element or by being located within a column described
by either <col> or <colgroup>.
Example
See HTMLImageElement.x for example code that demonstrates the use of the HTMLImageElement.y (and HTMLImageElement.x).
