How do you get text to fit within a div?

//parse text to respect line breaks added - increases readability.
//lines beginning with a ">" character are presented with a monospace
//(fixed-width) font - e.g., so equations will appear correctly
	function fix(e) {
		var par = e.parentNode;
		e.id = "";
		var pos = e.innerText.indexOf("\n");
		if (pos > 0) {
			while (pos > 0) {
				var t = e.childNodes(0);
				var n = document.createElement("PRE");
				var s = t.splitText(pos);
				e.insertAdjacentElement("afterEnd", n);
				n.appendChild(s);
				e = n;
				pos = e.innerText.indexOf("\n");
			}
			var count = (par.children.length);
			for (var i = 0; i < count; i++) {
				e = par.children(i);
				if (e.tagName == "PRE") {
					pos = e.innerText.indexOf(">");
					if (pos != 0) {
						n = document.createElement("DIV");
						e.insertAdjacentElement("afterEnd", n);
						n.innerText = e.innerText;
						e.removeNode(true);
					}
				}
			}
			if (par.children.tags("PRE").length > 0) {
				count = (par.childNodes.length);
				for (i = 0; i < count; i++) {
					e = par.children(i);
					if (e.tagName == "PRE") {
						e.id = "";
						if (i < (count-1)) {
							var e2 = par.children(i + 1);
							if (e2.tagName == "PRE") {
								e.insertAdjacentText("beforeEnd", e2.innerText+"\n");
								e2.removeNode(true);
								count = count-1;
								i = i-1;
							}
						}
					}
				}
			}
		} else {
			n = document.createElement("DIV");
			par.appendChild(n);
			n.innerText = e.innerText;
			e.removeNode(true);
		}
	}
