instead of the pretty print css, use the following css

I have just copied the above css and create a css file. For more themes visit this, themes gallery.

lets see an example which is a ruby code

class test
        def test
                return "test"
        end
end

code for above syntax highlighter is below

<pre class="prettyprint">class test
        def test
                return "test"
        end
end
</pre>
<script>prettyPrint()</script>

It is pretty straightforward.

2. Adding Line Numbers

class test
        def test
                return "test"
        end
end
