Subject: [pmg-devel] [PATCH widget-toolkit v1 3/6] gauge widget: add support for a dark theme and dynamic theme switching
Date: Wed, 8 Mar 2023 17:36:57 +0100 [thread overview]
Message-ID: <20230308163658.2453420-2-s.sterz@proxmox.com> (raw)
In-Reply-To: <20230308163658.2453420-1-s.sterz@proxmox.com>
the gauges in the data center overview should use a dark style if the
relevant css variables are set. this also makes it possible to switch
the colors dynamically by adding an event listener
