| Available: | since 1.0 |
Getter/setter for the margin-box of node.
Introduction and Usage¶
See the CSS spec for details on box model and what margin-box means.
This method will either return the margin-box size of a node:
1 2 3 | <script type="text/javascript">
var marginBox = dojo.marginBox(domNode);
</script>
|
... or set the node's width/height such that it's margin-box size becomes as specified:
1 2 3 4 | <script type="text/javascript">
// 300px x 150px
dojo.marginBox(domNode, {w: 300, h: 400});
</script>
|
In either usage it returns an object in the expected format of box. The object might look like:
{ l: 50, t: 200, w: 300: h: 150 }
for a node offset from its parent 50px to the left, 200px from the top with a margin width of 300px and a margin-height of 150px.
