the HTML spec say so that the width and height attributes must be positive integers, but have no mention on what browser should do if it's a negative value. Other browsers ignore the attribute with a invalid attribute and render the tag with the width default value. ``````

W3C (World Wide Web Consortium in charge of rules and practises web browsers and web pages is what Mozilla follows. Firefox is playing rather strict these days. May find it breaks in a update for another browser sooner or later.

If it does not pass https://validator.w3.org/ for HTML or https://jigsaw.w3.org/css-validator/ for CSS then you are doing it wrong.

Making exceptions to rules is not abiding by the rules.

You'll have to hit up some coding places/forums for help. I do some but not enough to help you.

Note : Firefox 57 Quantum release date Nov 14th https://www.mozilla.org/en-US/firefox/quantum/ Note : Legacy Extensions will be disabled and or removed.

Please let us know if this solved your issue or if need further assistance.
