I wrote a module that needs to add some markup to page.ss.
How can I do that without changing Page.ss or anything else which is not included into the module-stack.
Do you need to specifically add something to Page.ss, or to the page which gets rendered?
If it’s the latter, you could just use a middleware… that will give you access to the complete output from the site, and you can manipulate it as you see fit:
I have exteneded Varchar before and added functions there / changed them.
Then in templates you can write:
$Email.Hidden or $MyPercentage.Nice
