CSS

Definition

CSS, or Cascading Style Sheets, is a stylesheet language used for describing the presentation of a document written in HTML or XML. It allows web designers to control the layout, colors, fonts, and overall aesthetics of web pages. By separating content from design, CSS plays a crucial role in making interactive data visualizations visually appealing and accessible across various devices.
