modification, you could use this example to create a real-world, useful bar graph or

moving through water, slowing down as it goes, or a ball falling through the air,
gaining speed due to gravity. The other task I tend to use transitions for, beyond
the examples you've already seen throughout this chapter, is making information
boxes appear. You can see a great example of this on the Monty Python King Arthur
example blog-site.html page if you hover over the “More details (+)” lines at the
bottom of each blog post summary. The opacity and height of the footer increase,
revealing expanded blog post information ( Figure 5.21 ).
