Font Awesome Background color

Question

When using the brilliant Font Awesome, how can I make the icons not transparent - for instance if I want to use http://fortawesome.github.io/Font-Awesome/icon/chevron-circle

Answer 1

you can use fa-stack with the fa-circle icon under the other to have better control on the pixel just at the border:

with:

.icon-a {
    color: #FFF;
    font-size: 0.9em;
}
.icon-b {
    color: #000;
}
