On W3C validator my website is getting the following error:

How can I fix that?

Answer 1

Per HTML spec, you can use only integers with just a comma separating them on the coords attribute: https://html.spec.whatwg.org/multipage/infrastructure.html#valid-list-of-integers

So you have to round the floating-point values and remove the spaces between them.
