I'm not too familiar with bootstrap, so please correct me if i am wrong anywhere, but it seems that Darkstrap should remove the following two CSS rules.
[class^="icon-"],
[class*=" icon-"] {
background-image: url("../img/glyphicons-halflings.png");
}
.icon-white,
.nav-pills > .active > a > [class^="icon-"],
.nav-pills > .active > a > [class*=" icon-"],
.nav-list > .active > a > [class^="icon-"],
.nav-list > .active > a > [class*=" icon-"],
.navbar-inverse .nav > .active > a > [class^="icon-"],
.navbar-inverse .nav > .active > a > [class*=" icon-"],
.dropdown-menu > li > a:hover > [class^="icon-"],
.dropdown-menu > li > a:hover > [class*=" icon-"],
.dropdown-menu > .active > a > [class^="icon-"],
.dropdown-menu > .active > a > [class*=" icon-"],
.dropdown-submenu:hover > a > [class^="icon-"],
.dropdown-submenu:hover > a > [class*=" icon-"] {
background-image: url("../img/glyphicons-halflings-white.png");
}
Why? Well, it assumes that your Bootstrap is a local instalation, rather than a CDN installation from http://www.bootstrapcdn.com/.
Now, unless i am mistaken, there is no need for this correct? By removing it, the glyph location will default back to the original bootstrap location, which will be identified based on the location on the bootstrap css file. Supporting both CDN and local installations.
