using Javascript, it is easy to programatically select the text inside a textarea or input text element. How about for
<span>The quick brown fox jumps over the lazy dog</span>
is it possible to use JavaScript to select the words "quick brown fox"? Or select the whole sentence?

You will need some way to manipulate the span tag. Such as an id, but then in javascript I would edit some of the style properties. You could have a property for everything you want to highlight like what is shown below.
.HL {
background: #ffff99;
color: #000000;
}
If you do that then you will need to get a reference to the specific tag.
DocumentgetElementsByTagName("title")
Otherwise Document.getElementByID("ID") is good for unique ids.
Then using setAttribute(name, value) To change the class to the one given.
This is just a simple example but there are many ways to do this.
<span id="abc" class=""> Sample </span>
var temp = Document.getelementByID("abc");
temp.setAttribute('class', 'HL');
