Thank you. Amazing css.

From the command line you now need to use --css=pandoc.css or -c pandoc.css not --css pandoc.css

Hello everyone. I stuck at one place while converting html to word file. I want to add stylesheet_green.css to html but it is displaying only data not css in word file. Please suggest me what mistake I am doing.
Code is:

import pypandoc
output = pypandoc.convert(source='demo.html', format='html', to='docx', outputfile='swar.docx', extra_args='--css=stylesheet_green.css'])
 

Just a note: When running from command line with the latest pandoc v2.2.1, it works only when passed the --standalone or -s flag:

pandoc -c pandoc.css -s in.md -o out.html

@swarnimaeverest pandoc doesn't interpret the css for docx, only for doc, see jgm/pandoc#4354

Under what license did you release that css? Could you include a license notice?

I second typetetris. In the meantime, I will include your name in a comment, if that's not a problem.

Great stuff! Really makes a nice looking layout. However, wondering what is the point of this?

pre {
  white-space: pre;
  white-space: pre-wrap;
  word-wrap: break-word;  /* (this) */
}

As is, it breaks the format I put my code blocks in. For example, given

```java
boolean hasAnyAddressValue =
	location.hasLine1()
	|| location.hasLine2()
	|| location.hasCity()
	|| location.hasState()
	|| location.hasPostalCode();
```

Will generate,

However, when that line is commented out, I get the (more pleasing) output as below,

FWIW, I am compiling this using pandoc -t html5 --css pandoc.css file.md -o file.pdf.

For those interested in code readability, I added background-color: #ececec; in the block pre, code, kbd, samp {}
and added this block for code blocks :

pre.sourceCode, code.sourceCode {
    background-color: #ececec;
}

Here is a screenshot for the inline code :

Thanks!

Just a note: When running from command line with the latest pandoc v2.2.1, it works only when passed the --standalone or -s flag:

pandoc -c pandoc.css -s in.md -o out.html

This saved me, thank you!

btw. pandoc >= version 2.11 comes with built-in CSS that's fairly similar... see https://pandoc.org/MANUAL.html#variables-for-html

This is wonderful. I am now able to charge two times more money when generating docs for customers 😇 (in my dreams...)

THANK YOU!

Just to make @mb21's comment a bit more tangible:

From version 2.11 onwards you can just do (and it will get you fairly close):

pandoc -s README.md -o index.html -M document-css==templates/styles.html

@athalhammer you don't even need to set the document-css variable... that should be the default...

Thanks, @mb21, makes sense!

I have no idea what I'm doing wrong, but I cannot get this to work with line breaks.

This is wonderful and going to be commonly used by me. Thanks SO much!

Is there a way to add color to python code?

I see color in the html, but the it's printed in b&w...

I don't know if this css is still being mantained or if there are other standards right now.
