此时元素符号上不允许使用属性宽度和高度

Question

Should width and height attribute not be used on SVG's symbol ?

These are being used in MDN examplehttps://developer.mozilla.org/en-US/docs/Web/SVG/Element/symbol

How to solve this validation error?

Answer 1

Just linking back the the GitHub issue https://github.com/validator/validator/issues/930 and response for anyone that comes across this:

SVG 1.1 https://www.w3.org/TR/SVG11/struct.html#SymbolElement didn't allow width and height for the symbol element. But apparently the SVG2 spec does https://www.w3.org/TR/SVG2/struct.html#SymbolElement .

So I'll update the checker to allow those.

Till it is fixed, you can ignore it from the commandline directly with a regex or a series of reges with the filterfile paramater https://github.com/validator/validator#--filterfile-filename
