CSS Colors
What are CSS Colors?
CSS Colors are used to change the color of text, backgrounds, borders, and many other HTML elements. They make webpages more attractive, improve readability, and help highlight important content. CSS supports several ways to specify colors, including color names, hexadecimal values, RGB, RGBA, HSL, and HSLA.
Why Use CSS Colors?
Colors improve the visual appearance of a website and create a better user experience. They help organize content, draw attention to important information, establish brand identity, and make websites easier to read and navigate.
