Border extension for rounded corners
As a type of border, a radius border can be drawn by using -ah-border-radius:. Specify such as -ah-border-radius: 15pt 10pt;, then the default value will be set as a horizontal diameter (vertical diameter when -ah-writing-mode: vertical-rl;). The second value is the other diameter. If omitted, it will be regarded as a default value, and it cannot be rounded if either diameter is less than zero.
