Shrinks v4shims

[vingle]

Overview

Groups identical selectors, removes extra carriage returns, but doesn't fully minify. Reduces the file size from 42.5kb to 21.9kb.

Before

Each FA class gets its own 4 lines to define one of two fonts and weight. There's an extra space between each selector and selectors are spaced.

After

The shims are grouped for each font, reducing duplication. Carriage returns are reduced. ie:

.crm-i.fa-envelope-o,.crm-i.fa-star-o… {
    font-family: "Font Awesome 6 Free";
    font-weight: 400;
}
.crm-i.fa-twitter-square,.crm-i.fa-facebook-square… {
    font-family: "Font Awesome 6 Brands";
    font-weight: 400;
}
.crm-i.fa-glass:before { content: "\f000"; }
.crm-i.fa-envelope-o:before { content: "\f0e0"; }
