Uzair Farooq

I want to absolute position an element in iframe relative to the document. I’m using this

.myClass
{
    position: absolute;
    top: 0;
    left: 0;
}

but it do not position the element at top left of document, it’s positioned at top left of the iframe.
How to apsolute position it to the document? jquery/javascript solutions are acceptable
