postcss-short-border is a PostCSS plugin that simplifies writing CSS border properties by using shorthand syntax. It allows defining border width, style, and color in a single property, like border: 1px black dashed;, automatically expanding it to the standard border-width, border-style, and border-color properties. This streamlines your CSS, improves readability, and reduces code verbosity, all while adhering to standard CSS practices. It's a valuable tool for developers seeking cleaner and more maintainable stylesheets.
