'Reskinnable' SVG Symbols: How to Make Them (..and Why)
SVG icons are increasingly used in modern web design, thanks to their scalability, small file sizes, and CSS styling capabilities, making them ideal for responsive websites. Although SVG can be styled using CSS, this only works if the SVG code is embedded in the HTML page. This means that a single part of the SVG cannot be modified unless the SVG is embedded. This article introduces the concept of "removable SVG symbols", where the "skeleton" of the SVG image remains unchanged, but the surface appearance can be easily changed. The article proposes a solution to the problem of not being able to modify a single part of SVG.
