The border radius property is a simple property you can use to add rounded corners to an element. It lets you adjust the rounding of the corners of an element—rather than have them be completely square. These values can be used with the visual tools of ToolFlora's Border Radius tool. You can modify the radius and watch how the corners change, thus getting the concept of the effect of different radii. Useful when deciding on rounding to a suitable level in a specific design. You can also use ToolFlora to play with different border radii and automatically output the CSS for your design.
