Style the first word of module or page title

Today I will show you how to style the first word of module or page title like this:

Hello World

CSS doesn’t support this feature until now so we will make it by the help of JavaScript.
Here is the magic code to style the first word of a title

<script type="text/javascript">
function getElementsByClass(searchClass,node,tag) {
	var classElements = new Array();
	var j = 0;
	if ( node == null )
		node = document;
	if ( tag == null )
		tag = '*';
	var els = node.getElementsByTagName(tag);
	var elsLen = els.length;
	var pattern = new RegExp('(^|\\s)'+searchClass+'(\\s|$)');
	for (var i = 0; i < elsLen; i++) {
		if ( pattern.test(els&#91;i&#93;.className) ) {
			classElements&#91;j&#93; = els&#91;i&#93;;
			j++;
		}
	}
	return classElements;
}

//Add span to page title
function addSpanToPageTitle (firstword,el) {
	var modules = getElementsByClass (el, null, "div");
	if (!modules) return;
	for (var i=0; i<modules.length; i++) {
		var module = modules&#91;i&#93;;
		var title = module.getElementsByTagName ("h2")&#91;0&#93;;
		if (title) {
			if (title.getElementsByTagName("span").length == 0) {
				text = title.innerHTML;
				var pos = text.indexOf(' ');
				if (firstword && pos!=-1) {
					title.innerHTML = "<span class='pagetitle'>"+text.substr(0,pos)+"</span>"+text.substr(pos);
				}else{
					title.innerHTML = text;
				}
			}
		}
	}
}

//Add span to module title
function addSpanToModuleTitle (firstword,el) {
	var modules = getElementsByClass (el, null, "div");
	if (!modules) return;
	for (var i=0; i<modules.length; i++) {
		var module = modules&#91;i&#93;;
		var title = module.getElementsByTagName ("span")&#91;0&#93;;
		if (title) {
			if (title.getElementsByTagName("span").length == 0) {
				text = title.innerHTML;
				var pos = text.indexOf(' ');
				if (firstword && pos!=-1) {
					title.innerHTML = "<span class='modtitle'>"+text.substr(0,pos)+"</span>"+text.substr(pos);
				}else{
					title.innerHTML = text;
				}
			}
		}
	}
}
window.onload = function() {
    addSpanToPageTitle('*','contentpaneopen.*');
    addSpanToModuleTitle('*','ja-moduletable.*');
};

</script>

the function addSpanToPageTitle for Page title and addSpanToModuleTitle
this code

    addSpanToPageTitle('*','contentpaneopen.*');

for page title, JavaScript searches for class “contentpaneopen” when it find it, it searches within that class for tag “h2” as you can see on line 27

        var title = module.getElementsByTagName ("h2")[0];

this tag contains Hello World like this

<h2>Hello World</h2>

JavaScript will separate the first word “Hello” and wrapped it with “ span.pagetitle { color: #0000ff; }
