Is this the right place to post my question?
No, ask your question on the questions page.
Is it possible to change the standard - setting "text color" from black to green ?
Change the text color for your entire wiki is to change the "color" setting in your skins' .css file.
For instance in
How do I change the page Title
See Page Directives for the page directive (:title:)
How do I get comments into my code?
See Comment Markup
How do I disable the buttons like "View", "Edit, "History" etc at the top of my pmwiki page.
Also to disable the "text" on the top of my wiki, there's always posted the name of my wiki and the directory the user actually is.
This are possible in several different ways
- change the Skin Templates. (Note that by merely editing out the buttons, the actions they command will still be available for users who know how to operate PmWiki by typing the request URL manually.)
- use the page directive
- change the Site.Page actions page
How do I hide the sidebar when a page is being edited (?action=edit is at the end of the url)?
How do I change the colour of a horizontal line?
Is this the right way?
Another solution is to change the formatting of hr in your local.css file.
