Here is a demonstration of Round Corner Boxes Created with CSS.
To get the code for this demonstration click on View>Source, or View>Page Source then copy and paste into your editor.
Thanks to Stu Nicholls at CSS Play for his GREAT experimental CSS which I took to sort of an extreme final production!
This really isn't very practical, but it goes to show just how far you can go creating Round Corner Boxes with CSS Only!
This Demonstration also gives you an idea about creating graphic-free link (menu) roll-overs using only CSS Borders.
