Subject: Use new bg/fg utilities and data-bs-theme (#42451)
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a1ce7915c25295aab9e3ef1841dbccc775d6f236;p=thirdparty%2Fbootstrap.git

Use new bg/fg utilities and data-bs-theme (#42451)

Replace legacy theme classes across examples with new utility classes and theme attributes. Changes include swapping .bg-dark/.navbar-dark/.text-bg-dark/.link-body-emphasis for bg-black, bg-90, fg-white, fg-body, adding data-bs-theme="dark" where appropriate, removing nav-pills, adjusting icon nav links to use flex-column and removing svg mb-1 spacing, and simplifying sidebar nav classes. Updated example files: album, cheatsheet, headers, navbar-static, navbars, and sidebars.
