Warning about non standard property "zoom" in page php files

[speedbird182]

This is a: Bug/Feature Request

Details

When loading any page with the Developer Tools open, it produces a warning on every page load:

This page uses the non standard property “zoom”. Consider using calc() in the relevant property values, or using “transform” along with “transform-origin: 0 0”.

This shows as being in every page.

3. any additional info to help reproduce

These common fixes didn't work for my issue

• [Yes ] I have tried removing/destroying my container, and re-creating a new container
• [Yes] I have tried fresh volume data by backing up and moving/removing the old volume data
• [Yes ] I have tried running the stock docker run example(s) in the readme (removing any customizations I added)
• [Yes] I have tried a newer or older version of Docker Pi-hole (depending what version the issue started in for me)

This is not an issue. It's just a minor warning. It is generated by the Bootstrap CSS used by the web interface. This Bootstrap version uses a few "hacks" for older browsers and newer browsers show a warning, but there is nothing wrong. Newer browsers simply ignore the hacks and use the correct CSS rules.

I will close this issue because we don't fix external bugs and this is just a warning.
