How do I fix these errors, since everything has gone to HTML 5?

Question

I am needing to add/correct some stuff in the CSS page for my website and not sure what to add or edit for the following errors:

Line 50: The allowtransparency attribute on the iframe element is obsolete. Use CSS instead

Line 50: The frameborder attribute on the iframe is obsolete. Use CSS instead

Line 135: Bad value 0% for attribute aria-valuenow on element div : Expected a decimal point, e, E or a digit but saw % instead.

Any assistance would be greatly appreciated.

The allowtransparency attribute is an old IE only thing with no real css fix for it. You can wrap that attribute in a conditional comment so it validates and IE recognizes it...

The frameborder attribute doesn't exist in HTML5. You can use css "border:0" on a class or id associated with your iframe, or the ifram element itself, and remove the frameborder attribute from the html.

The value for the aria-valuenow attribute needs to be a plain number. The % symbol is not allowed.

Thanks Jon, What number would I use instead of %, since this is for a manually edited progress bar?John
