  <p>The blue box and the text are child elements of the element that has a photo background. The child elements do not inherit the opacity setting on the parent. This is done using a jedi mind trick, aka "JavaScript".</p>
  <p>The rest of this is just filler text. Don't read this, you're just wasting your time. Are you serious? You're still reading? I'm not lying, this is just filler. I just need this to wrap below the box. That's all.</p>

ThatsNotYoChild.js, by Louis Lazaris
Explanation: http://www.impressivewebs.com/fixing-parent-child-opacity/
This is a hacky workaround to let you use opacity on any element and prevent the child elements from inheriting the opacity.
Works in IE8+.
If anyone can get line 23 working in IE7, it will be fully cross-browser.
function thatsNotYoChild(parentID) {

    var parent           = document.getElementById(parentID),
        children         = parent.innerHTML,
        wrappedChildren  = '<div id="children" class="children">' + children + '</div>',
        x, y, w, newParent, clonedChild, clonedChildOld;

    parent.innerHTML = wrappedChildren;
    clonedChild = document.getElementById('children').cloneNode(true);
    document.getElementById('children').id = 'children-old';
    clonedChildOld = document.getElementById('children-old');
    newParent = parent.parentNode;

    clonedChildOld.style.opacity = '0';
    clonedChildOld.style.filter = 'alpha(opacity=0)';

    function doCoords () {
      x = clonedChildOld.getBoundingClientRect().left;
      y = clonedChildOld.getBoundingClientRect().top;
      if (clonedChildOld.getBoundingClientRect().width) {
        w = clonedChildOld.getBoundingClientRect().width; // for modern browsers
      } else {
        w = clonedChildOld.offsetWidth; // for oldIE

      clonedChild.style.position = 'absolute';
      clonedChild.style.left = x + 'px';
      clonedChild.style.top = y + 'px';
      clonedChild.style.width = w + 'px';

    window.onresize = function () {




// call the function and pass the ID of the parent that has opacity set.
