Use CSS Border Generator
Generate a CSS border shorthand from width, style and a parsed color value. Start with the sample, select the options and run the tool. Copy or download the result after reviewing it.
Behavior and limits
The width is expressed in pixels and color syntax is checked with the existing color parser. The result is a single shorthand declaration. Double and dimensional border styles depend on sufficient width and the element’s actual background.
