CSS Lint ignore all IE6 and IE7 based errors

I'm using Sublime Text 3, and CSS Linter.

In my settings I've put the ignore rule, and currently there is only the "outline-none" rule, I'd like to include all the rules which refer to IE6 and IE7 based errors.

Is there a list what are the IE6 and IE7 rules so that I can put them in the ignore array?

My CSSLint.sublime-settings look like this:

// CSSLint rules you wish to ignore. Must be an array. Leave blank to include all default rules.
{
    "ignore": ["outline-none"]
}

To answer my own question, in the end I figured how to do what I need:

{
    "user": {
        "debug": false,
        "delay": 0.25,
        "error_color": "D02000",

                ],
                "warnings": ""
            },
            "eslint": {

            },

                ],
                "newcap": false
            },
            "php": {
                "@disable": false,
                "args": [],

            }
        },

        },
        "python_paths": {
            "linux": [],
            "osx": [],
            "windows": []
        },
        "rc_search_limit": 3,
        "shell_timeout": 10,
        "show_errors_on_save": false,
        "show_marks_in_minimap": true,
        "syntax_map": {
            "html (django)": "html",
            "html (rails)": "html",
            "html 5": "html",
            "php": "html",
            "python django": "python"
        },
        "warning_color": "D02000",
        "wrap_find": true
    }
}

Just go to Preferences > Package Settings > SublimeLinter > Settings - User and paste the above in the opened file.

These are the options that I found not to be of practical importance, so I just ignored them.

Hope it helps :)
