Many Web pages are static. Users can’t interact with them, except for clicking on links.
Some Web pages are interactive, like the page you’re reading now. You can expand and collapse items in the menu to the right. You can move the mouse over the tabs at the top of the page, and they jump around a little.
Other CoreDogs pages let you type in solutions to exercises. The solutions are saved. They’ll be there next time you look at the page.
In this chapter, we’ll look at how Webers make pages interactive.
