Custom Host Banner 作成者: dev.andyb

Display a custom banner on the page based on the host.
Each host can have a banner with different colour and text.

If you are a developer, QA engineer etc switching between different environments that all look the same, this tool can help you see where you are, and stop you accidentally changing the prod site instead of the test site...

The code is here: https://github.com/andyb3/custom_host_banner
