Build, test, and debug regular expressions
This regex matches CSS transform translate() function calls, capturing two numeric arguments separated by a comma with optional whitespace. Each capture group matches numbers with optional negative signs and decimal points (e.g., -10, 3.5, 0.75). It's useful for extracting X and Y translation values from CSS stylesheets, inline styles, or SVG transform attributes. The gm flags enable global matching across multiple lines.
