HTML Validation "img attribute width/height has invalid value"

Question by Guest | 2014-06-03 at 23:55

For the following HTML code:

<img src="img.jpg" alt="img" width="100px" height="100px">

I get these two errors in my HTML Validator:

Warning: <img> attribute "width" has invalid value "100px"
Warning: <img> attribute "height" has invalid value "100px"

Can someone explain to me why this causes an error and how to get rid of this error message?

The declaration of "px" is not necessary with the attributes "width" and "height", because the values stated here are "px" by default. So, just write "100" instead of "100px":

<img src="img.jpg" alt="img" width="100" height="100">

This should fix the HTML Validator "errors".
