This is intended as a reference to the various on-site stylesheets, along with a bit of information on CSS.

The appearance of PM pages can be customized via CSS files.

Perlmonks OnSite CSS Files

These are the CSS Themes at perlmonks:

All themes can be selected via the "Theme container" combo box in "Theme configuration" of the Display Settings node.

Note:entering their respective URI into the Link to External CSS stylesheet textbox or by including them via a import directive in the On-Site CSS Markup textbox will miss some colour settings, since at the time of this writing there are still colours configured directly in tags with BGCOLOR directives. Those colours are pulled out of the database and inserted on the fly.

This comprises the following:

classin tagsDescription
.replytrheaders of replies
.reply-bodytrbody of replies

Tweaking the Stylesheet

With that as base, you can further tweak the appearance to your liking by including CSS directives below, which will override any definitions present in the previously imported file.

You could load e.g. the red theme as base and provide for a exquisite pink background as follows:

body { background: #df7fc0; } tbody.nodelet td, td.nodebody { background: #e888ff; } tbody.nodelet th, th.nodehead { color: #ffff00; background: #b000f0; }
Note that the definitions you set out in On-Site CSS Markup will be pulled out of the database and included in every page you retrieve. If your styleshets grow lengthy, consider placing them in a file off-site and including them as set out above.

Changing the appearance of your homenode

Insert a link to a stylesheet at the top of your User's Bio textbox:
<style type="text/css"> @import url(""); </style>
