Ignore margin of parent div that uses auto

Issue

I would like to have a div ignore the margin of its parent div as in such a case:
html:

    <div class="wrap">
        I'm annoying!
        <div class="myown"> I don't want to have that annoying guy's margin! </div>
    </div>

css:

    .wrap {width: 200px; margin: 0 auto;} /* Do not change */
    .myown{margin: 0;}

I found this answer but it still doesn't work!
Here it is when ran: http://jsfiddle.net/KYbq3/2/
Under my circumstances I cannot change .wrap but only .myown.

Solution

If you want it to "break out" of the container, then your only option seems to be position: absolute;. The problem with it is that it takes the element out of the natural flow.

.myown{ 
    position: absolute; 
    left: 0; 
    width: 100%; 
}
