| /** |
| * corner() takes a single string argument: $('#myDiv').corner("effect corners width") |
| * |
| * effect: name of the effect to apply, such as round, bevel, notch, bite, etc (default is round). |
| * corners: one or more of: top, bottom, tr, tl, br, or bl. (default is all corners) |
| * width: width of the effect; in the case of rounded corners this is the radius. |
| * specify this value using the px suffix such as 10px (yes, it must be pixels). |
