No longer possible to color text in Markdown

[peterflynn]

Earlier, GFM allowed you to create colored text this way:
<font color="red">Status: **Not yet implemented**</font>

That used to work. But at some point the <font> tag was removed from the HTML sanitization whitelist.

I suppose it got removed because it's deprecated in HTML5. (Aside: the color attribute is still on the whitelist. Should it be removed too? As far as I know, there's no other HTML tag it can be used on...)

So, can we have a new supported way of coloring text in sanitized GFM now?

Here's one possibility: allow a very strict use of style for setting colors. Only attributes that exactly match the form style="color: #xxxxxx" would be permitted. For something as constrained as that, you could enforce it with a simple regexp like ^color:\s*#([0-9a-fA-F]{3}|[0-9a-fA-F]{6})$.

Thanks for the request. This gem only handles markup to HTML conversion, but I've logged your feature request for our design team to consider.

Any news on this? Has there been a decision? Hopefully, this will be supported. 😃

I second that opinion. Actually and way to color text would be great.

Me too I support this feature, it can be great to at last color the text, but using style="" to set the colors is better for me, I normaly use with <em></em>,<strong></strong>, <u></u>, <s></s>… well mainly text format', or in <blockquotes> too, but it don't work on github…

Adding a way to add a background color can be great too, when I make <table></table> it can be hard to easily see the entries and separators <th></th>.

Yes, please!

I like to write color-coded documentation. When I document a complicated set of instructions, I like to put a list of the parameters that are needed at the beginning and then give each parameter it's own color.

Plus, for commenting student jupyter notebooks, it would be awesome to write my comments in color.

I agree that we have to have the color tags back.

[paulnakroshis]

For the time being, I can use <span style=“color:green;”> text goes here</span> Which allows html to render the text…but some markup simplicity would go a long way here… Another item that would be nice would be to be able to color the background color of a Jupyter notebook cell…

@paulnakroshis really? I can't use that at all.. the style attribute is disallowed.
