have you considered adding another parameter in the EnhancedHTML2 module to allow header injection with a more complete list of css and js?
It is quick to customize in the code, but just for a sake of standardized version 🙂
Actually I simply (and hope correctly as it works):
add a new param:
that I later inject in the header
ConvertTo-HTML -Head "$stylesheet`n$titletag`n$script`n$bootCSS`n$datatable" -Body $body
as simple as it is, allow a quick import of Bootstrap,Bootwatch,fonts and so on.
