Answer 1

Here is how I would do that:

JS

var container = document.getElementById('editor'),
    firstChild = container.childNodes[1];
if (container && firstChild) {
    var newPre = document.createElement('pre');
    newPre.setAttribute("contentEditable", "true");
    newPre.innerHTML = "boom";  
    firstChild.parentNode.insertBefore(newPre, firstChild.nextSibling);    
}
