Same example as <a href="create-vml-current.html" >here</a> but with style position set to absolute : |

| 81 |
|
|---|
| 82 |
<pre> |
|---|
| 83 |
|
|---|
| 84 |
style.addRule('v\\:*', "behavior: url(#default#VML); " + |
|---|
| 85 |
"position: absolute; display: inline-block;"); |
|---|
| 86 |
</pre> |
|---|
| 87 |
Doesn't seem to work. |
