End: Vacation (1).jpg, Vacation (2).jpg, Vacation (3).jpg, Vacation (4).jpg

By using CSS I am able to decorate the anchor tag! Before CSS buttons on websites were text in images between the anchor tags.

THIS WAS BAD. Loading images takes a significant amount of time, much more than the average visitor was willing to spend watching the page load. CSS is a way of decorating text based on selectors and classes which describe the style needed.

Thanks to CSS you don't have to compromise looks for speed. Take a look at some more examples of how CSS can decorate links to appear as buttons.

Don't Have the Time to learn CSS?

Although learning CSS would be ideal, there are many programs and websites that host programs to help you create buttons visually. The CSS for the buttons will be printed out to you once you reached a design you like! Try a CSS button creator now!

JPanel as a Container

In this tutorial, a new class (extension of JPanel), MainPanel.java has been added to the source files and is going to act as a common container for all instances of the ButtonPanel we create. The ButtonPanels are able to operate independently of one another.
