While I was coding the Notepad theme, I’ve learned some new CSS3 features and now I would like to share it with you. View the demo to see a Mac-like multi-level dropdown menu that I’ve created using border-radius, box-shadow, and text-shadow. It renders perfect on Firefox, Safari and Chrome. The dropdown also works on non-CSS3 compitable browsers such as IE7+, but the rounded corners and shadow will not be rendered.
The image below shows how the menu will look if CSS3 is not supported.
One Gradient Image is Used
A white-transparent image is used to achieve the gradient effect. Because the new CSS3 gradient feature is not supported by all browsers yet, it is safer to use a gradient background image.
The instensitiy of the gradient can be changed by shifting the background image up or down. Also, the gradient color can be easily adjusted by changing the background color.
I’m not going to explain the CSS line by line. The images below explain the key points on how this dropdown is coded.
