Creating A Bubble Effect With CSS
AEXT.NET, a blog focused on web design & development, is presenting a very detailed tutorial on creating bubbles effect (like Apple Dock) with CSS.
The tutorial includes two methods: CSS sprites (basic) & the image swapping (advanced) which will be generating the same visual output.
The effect is very functional specially for list items where items are small in size & the user may have difficulty in pressing the desired one.
