HTML5 Stroke Element

Question

I don't understand the stroke element. Can anybody clarify how it works?

Answer 1

'stroke' is not an element, but an attribute...
It's an attribute specific to svg elements (tags), and define the color used to draw outline of shapes: it require to also set a value to the "stroke-width" attribute to be effective (else you doesn't see any change of color on a default zero width outline ^^)
