Subject: Improve theme-color-level() using abs() (#24074)
X-Git-Tag: v4.0.0-beta.2~218
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=17fd2c9f84be84fb917f40212d2ddd88fe6a6d1e;p=thirdparty%2Fbootstrap.git

Improve theme-color-level() using abs() (#24074)

`abs()` gets the absolute value of `$level`.
That way, `if/else` statement can be completely eliminated.
