Are there any issues/risks with adding
extended_valid_elements: "style",to the tinyMCE.init object in notebook.py (around line 1810)? I ask because it seems that TinyMCE "removes" from edited and saved text any elements not specified in its valid_elements or extended_valid_elements options: http://wiki.moxiecode.com/index.php/TinyMCE:Configuration/valid_elements http://wiki.moxiecode.com/index.php/TinyMCE:Configuration/extended_valid_elements . For example, I can open an editor, click on the HTML icon to "Edit HTML Source," and paste, e.g., Hello there!<style> div.worksheet {background-color: goldenrod;} </style> into a textarea. Alternatively, I can use the plain text editor to place this element outside a cell block. But by default, when I save the area with TinyMCE, it replaces <style> and </style> with <!-- and -->. That is, it comments out the style directive. If I don't include "Hello there!," the style does stay, but I need to remember to leave that area alone. It seems the worksheet's first two lines, with the sheet's title and system, are off-limits to TinyMCE. Another possible workaround is to add a "field" for custom CSS to this area. I'm not sure if this would cause compatibility headaches. Anyway, one advantage to preserving style elements across simple edits in a browser is that I can use something like (you may need to fix the indentation) s = '' @interact def _(radius=slider(0.0,1.0,0.05,0.5,'Border radii'), c_in_bord = Color('blue'), c_in_back = Color('white'), c_ac_bord = Color('blue'), c_ac_back = Color('white')): global s s = '' s += '<style type="text/css">' s += 'div.worksheet {-moz-border-radius: %fem;}' % radius s += 'textarea.cell_input, pre.cell_input, textarea.cell_input_hide, pre.cell_input_hide {border-color: %s; background-color: %s; -moz-border-radius: %fem;}' % (c_in_bord.html_color(), c_in_back.html_color(), radius) s += 'textarea.cell_input_active, div.cell_input_active {border-color: %s; background-color: %s; -moz-border-radius: %fem;}' % (c_ac_bord.html_color(), c_ac_back.html_color(), radius) s += '</style>' html(s) to tune a color scheme --- with instant feedback, thanks to auto updates! --- and paste the output of "print s" into the plain text editor to apply it. Of course, a built-in function which returns a more detailed control panel and other changes to server-side code could automate this. Since this panel may take up lots of space, I propose crossing the input grid and color selector controls, to get a new control similar to that in the attached screenshot. Here, all I've done is tweaked a Farbtastic demo, $SAGE_ROOT/local/notebook/javascript/jquery/plugins/farbtastic/demo2.html , so this is still just a concept. Thoughts? By the way, I may have missed this in the documentation, but is it possible to set a transparent background for 2D plots in Sage? Thanks.
