Line height for a specific font

Question

In css I have defined a custom font for a specific rage of characters:

@font-face {
    font-family: Sahel;
    src: url(../font/Sahel-FD.ttf);
    unicode-range: U+0600-06FF;
}

@font-face {
    font-family: Sahel;
    src: url(../font/Sahel-FD-Bold.ttf);
    unicode-range: U+0600-06FF;
    font-weight: bold;
}

I want to change line-height only for this font, but adding this property in a @font-face rule has no effect.

How can I do that?
