CartoCSS

CartoCSS is a styling language used to customize the appearance of maps, similar to how CSS styles web pages. It allows cartographers and developers to define visual elements like colors, line thickness, and labels of map features (such as roads, rivers, or regions) in a straightforward, readable way. By writing CartoCSS rules, users can control how map data is visualized, making maps more informative and visually appealing. It’s an efficient way to apply consistent styles across complex maps, enhancing both their readability and aesthetic quality.
