Using Font family gets ignored in Sigil

[increase]

I am using <span class="first-letter">F</span>

as a drop case in epub3 with css as

.first-letter {
display:block;
float:left;
font-size: 5em;
line-height:0.8em;
color:#bf253c;
font-weight:normal;
padding-right: 8px
}

When I use font-family:SerpentisBlack; or any other font that I have loaded into the Fonts folder, it gets ignored in the text.

If I use a standard font i.e. font-family: "Comic Sans MS"; it works

.first-letter {
font-family: "Comic Sans MS";
display:block;
float:left;
font-size: 5em;
line-height:0.8em;
color:#bf253c;
font-weight:normal;
padding-right: 8px
}

Have you added an @font-face entry to the css?

Yes I did try that to no effect, do I add it like this
@font-face {
font-family: SerpentisBlack;
}

in addition to my .first-letter brace?

[doubleshuffle]

The full entry should look like this:

@font-face {
font-family: 'SerpentisBlack';
font-weight: normal;
font-style: normal;
src: url('../Fonts/SerpentisBlack.ttf');
}

Or .otf at the end, if it's an otf font.

Ah that's it thank ypu

There's actually a Sigil plugin that adds these entries automatically for all the fonts you add to the Fonts folder.

Number 8 on the list.

Just to clarify and recap; this had nothing to do with Sigil. This was incorrect epub coding/font embedding in general. The only reason Comic Sans was working was because it was available in your system fonts. It wouldn't have worked on any reader that didn't have Comic Sans available.
