一些规则
-
The first important thing to notice is the order of rendering elements. The globally valid rule for SVG files is, that later elements are
rendered atop
previous elements. The further down an element is the more it will be visible. -
SVG can be directly embedded in HTML or created dynamically with JavaScript and injected into the HTML DOM
