In this tutorial, I will investigate the use of Regular Expressions (Regex). Regex is an interesting, albiet at-first-glance, inscrutable-seeming tool in software development, known for its efficiency and versatility in searching and manipulating text based on patterns. Specifically, in this case, we will be exploring its use in matching hexadecimal values.
In this example, 'll explore a regex pattern designed to validate hex color codes. Hex color codes allow developers to specify colors in stylesheets and scripts. These color codes can come in two formats: a three-digit shorthand and a six-digit full notation. Mastering the regex to validate these inputs is not only practical but also enhances your understanding of both regex and color specifications in web design.
