Using a custom ttf font with Enfold

Hi, I followed the directions at http://justcreative.com/2013/01/22/how-to-use-custom-fonts-with-font-face-on-wordpress and uploaded the font files to enfold-child. I also put this in custom css –

@font-face {
    font-family: 'obelixproregular';
    src: url('obelixpro-cyr-webfont.eot');
    src: url('obelixpro-cyr-webfont.eot?#iefix') format('embedded-opentype'),
         url('obelixpro-cyr-webfont.woff2') format('woff2'),
         url('obelixpro-cyr-webfont.woff') format('woff'),
         url('obelixpro-cyr-webfont.ttf') format('truetype'),
         url('obelixpro-cyr-webfont.svg#obelixproregular') format('svg');
    font-weight: normal;
    font-style: normal;
}
h1, h2, h3, h4, h5, h6 {
    font-family: 'obelixproregular'!important;
}

But it’s not working. Private data below.
