I think there is a bug in HTMLII 9.
Your screenshot didn't upload
The message tells that I haven't make it the header with 16px of font-size.
If I change the order of the type of style (color before than font-size), the command control tells me that I haven't make it well the color of the style.
Sorry if I didn't speak it well I'm not an english speaker.
Mine is doing the same thing except I am actually writing violet just like says. I have checked it over and over and I come up with nothing to fix it.
okay your syntax for style is a bit off,
Instead of putting quotes are around each attribute and value you need to put a pair around all so it would be like this:
<p style="color: blue; font-size: 30px;">any text</p>
Thank you, it works.
