CodeMirror: HTML mixed mode

## HTML mixed mode

<html style="color: green"> <!-- this is a comment --> <head> <title>Mixed HTML Example</title> <style type="text/css"> h1 {font-family: comic sans; color: #f0f;} div {background: yellow !important;} body { max-width: 50em; margin: 1em 2em 1em 5em; } </style> </head> <body> <h1>Mixed HTML Example</h1> <script> function jsFunc(arg1, arg2) { if (arg1 && arg2) document.body.innerHTML = "achoo"; } </script> </body> </html>

The HTML mixed mode depends on the XML, JavaScript, and CSS modes.

It takes an optional mode configuration option, `tags`, which can be used to add custom behavior for specific tags. When given, it should be an object mapping tag names (for example `script`) to arrays or three-element arrays. Those inner arrays indicate [attributeName, valueRegexp, modeSpec] specifications. For example, you could use `["type", /^foo$/, "foo"]` to map the attribute `type="foo"` to the `foo` mode. When the first two fields are null (`[null, null, "mode"]`), the given mode is used for any such tag that doesn't match any of the previously given attributes. For example:

    var myModeSpec = {
      name: "htmlmixed",
      tags: {
        style: [["type", /^text\/(x-)?scss$/, "text/x-scss"],
                [null, null, "css"]],
        custom: [[null, null, "customMode"]]
      }
    }
