You'll need a text editor for creating HTML, CSS, and JavaScript. Some great free options are TextWrangler for Mac or Notepad++ for Windows. There are also many other options available and you can feel free to use your favorite text editor for any of the examples in this book.

You'll also need a browser. My personal favorite is Google Chrome, which includes some really helpful debugging tools for both CSS and JavaScript. Again, you can feel free to use your favorite browser for the examples in the book.

If you want to create images for your own designs, then Adobe Photoshop and Adobe Illustrator will be helpful, though they are not strictly necessary. Any images needed to set up the examples used in this book are included in the sample code.
