This slowdown seems to be in the new code for cell input/output
folding and nested line numbers, so I'll try to make that faster...

This is now fixed; it was
https://github.com/sagemathinc/smc/issues/199, which wasn't merged
into master and live yet, for some reason.

Re: [sage-cloud] CSS selector for styling content of Sage worksheet

[Harald Schilly]

Well, since there are usually several sagews files opened, wouldn't
any change of the css to one of them have implications to all the
others? That's probably not your intention. Not sure if this can be
solved in an easy way, and might involve writing some specialized
functions for this.

[sage-cloud] CSS selector for styling content of Sage worksheet

[Rob Beezer]

I'd like to heavily style the *content* of a  *.sagews  worksheet (a section or 
chapter of a textbook, say) by load()'ing an extensive CSS file.  But I don't 
want to interfere with styling on button bars and other UI elements.


So I'd like to use an overall selector to prefix the more specific ones and 
limit the scope to the actual input/output contents of the worksheet.


salvus-editor-codemirror-input-container-layout-1  seems to be the first one 
that does not contain any of the buttons above the content, but it also includes 
the left margin line numbers.


The range from  CodeMirror-lines  down to  CodeMirror-code  seem to be about 
right, but it is not clear if it would make a difference which one was used.


Any recommendations?

Thanks,
Rob
