[Tex/LaTex] \listings code style for HTML5 (CSS, HTML, JavaScript)

codeformattinghtmljavascriptlistings

I would like to create a code style for HTML5 that can be used with the \listings package.

An HTML5 document consists of three languages: CSS, HTML and JavaScript. That makes the whole thing a bit more complicated, because one can only define a keyword field for three languages.

I oriented myself on the style of the NetBeans IDE (Screenshot).
I have come very far. Nevertheless, there are some problems …

enter image description here

Bug #1
The keyword canvas occurs both as an HTML tag and a variable. I want the HTML tag to be blue but not the JavaScript variable within the <script> block.

Bug #2
Because I make blue slashes for the ending HTML tags, the forward slashes in my JavaScript texts also get blue.

Missing Feature #3
Identifiers (#square, .box) in the CSS code are not green.

Can anyone help me to solve these problems? I don't want to use \minted because I've got already a lot of code with \listings in my documents.

I have also created a minimal working example:

\documentclass{scrreprt}
\usepackage{color}
    \definecolor{lightgray}{rgb}{0.95, 0.95, 0.95}
    \definecolor{darkgray}{rgb}{0.4, 0.4, 0.4}
    \definecolor{purple}{rgb}{0.65, 0.12, 0.82}
    \definecolor{ocherCode}{rgb}{1, 0.5, 0} % #FF7F00 -> rgb(239, 169, 0)
    \definecolor{blueCode}{rgb}{0, 0, 0.93} % #0000EE -> rgb(0, 0, 238)
    \definecolor{greenCode}{rgb}{0, 0.6, 0} % #009900 -> rgb(0, 153, 0)

I know that the task is pretty tough! But maybe we can do that collectively?

An HTML5 code formatting could be used universally.

P.S. I have read that there are commands like usekeywordsintag and tagstyle. But everytime I want to use them I get the error:

! Package keyval Error: tagstyle undefined.

Update: I am still improving the code style. You can find the latest version here: https://www.writelatex.com/74567mmxwkw - I appreciate anyone who is testing :)

If you want to get a copy of the source code, you can get it here: https://dl.dropboxusercontent.com/u/74217418/stackexchange/tex/html5_listings_sample.tex

After much trial and error and the help of people here from the community I have come to a very attractive result.

The code is pretty intense, but it works. It would be nice if others could try it. Thus it is ensured that there are no errors. Unfortunately, all HTML elements and attributes, and CSS properties have to be entered manually. Maybe we can put together a list of all these items?

Together with the W3C specification it should be possible.

Here is the code:

\documentclass{scrreprt}

\definecolor{editorOcher}{rgb}{1, 0.5, 0} % #FF7F00 -> rgb(239, 169, 0)
\definecolor{editorGreen}{rgb}{0, 0.5, 0} % #007C00 -> rgb(0, 124, 0)

  morestring=[b]",
  morestring=[b]'
}
