Making glyphicons larger

[Andrew]

Hello,

I am trying to override the default glyphicons size. Trying these 
approaches didn't work:

.i {
[class*=" icon-"] {
width: 24px;
height: 24px;
background-position: 24px 24px;
}
}

or

[class*=" icon-"] {
width: 24px;
height: 24px;
background-position: 24px 24px;
}

Does anyone know of a better approach?

Thanks,

Andrew
