HTML Tags
HTML <svg> Tag
The
<svg>tag is used to embed Scalable Vector Graphics (SVG) directly inside an HTML document.
SVG graphics are resolution-independent, meaning they scale without losing quality and are ideal for icons, diagrams, charts, and illustrations.
SVG elements are part of the HTML5 specification and work seamlessly with CSS and JavaScript.
