Client website spec document (browser spec etc)

Does anyone have a standard website spec doc for clients suitable for Webflow sites using interactions, CMS, blog migration - nothing fancy or using 3rd party app integrations, that I’d deal with separately with. It’s a doc that I’ve always used to cover us from having to fix things that don’t work on old browsers (like IE now, for example). Client usually gets this via developers/digital project managers based on platform and design/functionality, so I’d like an up to date version specific to Webflow? Thanks!
