Can't change heading font

Total newbie, so this is likely basic…

My CSS h2 definition originally said…

h2 {
font-size: 125%;
margin: 0.33333333em 0px;
}

I wanted to change the color, so I added that, resulting in this…

h2 {
font-size: 125%;
margin: 0.33333333em 0px;
color: rgba(133, 174, 62, 1);
}

It worked. Next, I wanted to change the font, so I added that, resulting in this…

h2 {
font-family:“Arial Black”, Gadget, sans-serif
font-size: 125%;
margin: 0.33333333em 0px;
color: rgba(133, 174, 62, 1);
}

The font change had no effect. Any idea why not?

You’re missing the semi-colon after sans-serif.

Thanks! That did it.

This is the kind of thing jigsaw.w.org/css-validator is great for.
