[Feature] Support GitHub style

[seagle0128]

Hi, Thanks for the great package to preview the markdown buffer.

Could you please support GitHub CSS style?

Would this work for you?

(setq impatient-showdown-flavor 'github)

[seagle0128]

No. It's just change the markdown flavor, while not CSS style.

The preview should be like this.

[jcs090218]

Hmm... you mean these variables?

impatient-showdown/impatient-showdown.el

Lines 55 to 67 in 501d8eb

	(defcustom impatient-showdown-scripts
	'("https://cdnjs.cloudflare.com/ajax/libs/showdown/1.9.1/showdown.min.js"
	"https://cdnjs.cloudflare.com/ajax/libs/highlight.js/9.18.3/highlight.min.js"
	"https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@9.17.1/build/highlight.min.js")
	"File path for showdown highlight."
	:type 'list
	:group 'impatient-showdown)
	(defcustom impatient-showdown-links
	'("https://cdnjs.cloudflare.com/ajax/libs/highlight.js/9.18.3/styles/github-gist.min.css")
	"File path for showdown highlight."
	:type 'list
	:group 'impatient-showdown)

I have also make the template file custom variable, you can change the entire "look" by customizing the file path.

(setq impatient-showdown-preview-template "path/to/preview.html")

Hope these information help!

I guess impatient-showdown-preview-template impacts the html style.

[jcs090218]

impatient-showdown-preview-template is the HTML file use to render markdown. So you could define your own CSS on top.

[seagle0128]

So can you please add an option to insert into the HTML template, and/or a GitHub CSS template?

[jcs090218]

Hmm... not on top of my head. 😓 Unless there is a CDN GitHub CSS file we can reference on top of our html template. I have a quick Google Search on this, but came out without any good outcomes.
