Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
Please take two minutes to fill out our short survey.
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).
