Question about LESS function call

Hazan

I can't find the some function calls in .less files.

For example:

vendor\flarum\core\less\lib\App.less

Contains:

.App:before {
    content: " ";
    .header-background();
    border-bottom: 0;
    position: absolute;

   .affix& {
        position: fixed;
    }

   .scrolled& {
        .box-shadow(0 2px 6px @shadow-color);
    }
}

I can't locate this:

.header-background();

Anyone can help me?
Thanks ?

Hazan

Well, I found it in this path:

vendor\flarum\core\less\lib\mixins

Thanks anyway ?

Hazan

Umm I'm still stuck with that...

Another example:

vendor\flarum\core\less\lib\Search.less

Contains:

.Search-input {
  overflow: hidden;
  color: @muted-color;

  &:before {
    .fa();
    content: @fa-var-search;
    float: left;
    margin-right: -36px;
    width: 36px;
    font-size: 14px;
    text-align: center;
    position: relative;
    padding: 7px 0;
    line-height: 1.5;
    pointer-events: none;
  }

  input {
    float: left;
    width: 225px;
    padding-left: 32px;
    padding-right: 32px;
    .transition(all 0.4s);
  }

  .Button {
    float: left;
    margin-left: -36px;
    width: 36px !important;
    outline: none;
  }
}

I can't locate this:

.fa();

How can I find this quickly?

Hazan How can I find this quickly?

Font-Awesome is currently in less/lib/font-awesome.less) included in the core - we will likely pull it in via Composer in the future, though...

In fact, I just did this as part of updating Font-Awesome...
