How to add dynamic colors with CSS

Dynamic functionalities often associated with JavaScript can also be implemented using only CSS, as demonstrated by the ability to create dynamic colors through CSS variables. This approach, although unsupported by Internet Explorer 11, allows developers to incorporate colors defined by content editors without prior knowledge of the design system. Techniques such as using transparency, relative colors, the calc() function, and filter percentage values enable the manipulation of dynamic colors in a more efficient and powerful way. While CSS lacks certain capabilities like string concatenation for colors, relative colors provide a versatile method for color manipulation. The article also touches on supplementing CSS with SASS and JavaScript for additional color manipulation, highlighting that while dynamic colors might not be necessary for every project, they offer a valuable tool for creating responsive and interactive designs.
