Unifying stylesheets

Unifying stylesheets.

I have the habit to use two stylesheets. One is produced converting the odt source file, the other is automatically inserted, if need be.

Once I finish tweaking the styles and polishing the EPUB, I use the Calibre editor to suppress the unused CSS rules (Sigil can do it too).

Then I can mix (fusionner) the remaining parts ot the two stylesheets. However this process only puts one stylesheet on top of another. I would like to do better.

Question: I would like to know how to sort the items on the stylesheet to get a cleaner result and this way display possible redundancies like.

Code:

body
body
h2
h2
p
p
.small
.small

I think the only way to do this reliably is using programming tools which understand how CSS works. I know it can be done using a combo of Python and cssutils in a calibre user interface plugin or calibre editor plugin but some programming skills are required.

@jackie_w, for sorting items the plugin is enough, no programming skills needed.

I defer to your better experience if it can truly sort CSS without changing the intended styles.

I try it.

Thanks for your replies.

I tried it with Calibre book-edit but it failed...

Traceback (most recent call last):
File "calibre_plugins.sortcss.main", line 83, in sort_stylesheets
File "calibre_plugins.sortcss.main", line 117, in sort_stylesheet
File "calibre_plugins.sortcss.main", line 117, in <lambda>
AttributeError: 'CSSFontFaceRule' object has no attribute 'selectorText'

I'll ask for support on the Calibre forum

Stylesheets work on 'Last processed', is what gets used

so those with 2 definitions
If they both contain some of the same attributes, the last definition prevails, otherwise they merge.

But why make it obscure? Do the 'Combine' with an editor and KISS

Old, Arnold era Baen CSS had 3 body definitions over 3 stylesheets (one tha had no entries), obvious remnants of evolved 'automation' . Part ov my cleanup was to replace those 3 with a Single, clean CSS that did exactly the same in the end
