This headline uses the Verdana font at 18 pixel size and the color is navy. It stands out from the surrounding text, which is just the effect we want.
This headline matches the first headline. It uses the same style rule.
Here we have the third headline display. Surprise! It's the same as the previous two headlines. Everything looks consistent and you have a coherent page display.
This technique looks better and is easier to code! In the inconsistent styles example, we had to set up 3 different style classes to handle the three different headline displays. In this case, we just apply styles to the H2 tag itself and forget about creating extra classes or applying them inside the code.
