position:fixed when left/top/right/bottom aren't specified - desired results in FF/IE, but not in Safari

Question

Sorry to have to ask yet another position:fixed related question, but reading through various other questions and forum threads hasn\'t helped me with this one.

Answer 1

I had the same requirement, to position an element fixed at it's natural (default) static position with relation to the viewport. I ended up using this simple jQuery function.

function SetFixedPositioning(element) {
    var currentOffset = $(element).offset();
    $(element).css("position", "fixed");
    $(element).offset(currentOffset);           
}

Use it like this:

SetFixedPosition($("#element-to-position"));

My use case was a second level navigation menu that flowed into the document, then was fixed at that position.
