Center Twitter Bootstrap 3 Glyphicons in buttons

Question

I am now using Twitter Bootstrap 3 RC2 as well as Twitter Bootstrap which has moved into a separate repository. I have noticed, if used in a button with text the icon is no

Answer 1

For some vertical-align might not work due to positioning: If you look into .glyphicon class you'll see it is set to relative, try setting it to 'inherit' e.g:

.glyphicon.v-centered {
    position: inherit;
    vertical-align: middle;
}

This should also work for icons not in buttons, e.g. tabs.
