It's to simple you could add to the manifest's permissions field : See web_accessible_resources

 , "web_accessible_resources": [
        "mystyle.css"
    ]

and also add this in content_scripts

"content_scripts": [
    {
        "matches": [""],
        "css": ["mystyle.css"],
        "js": ["jquery-1.10.2.min.js","content.js","my.min.js"]
    }],

you also add same thing using Programmatic injection and insertCSS().

chrome.tabs.insertCSS(integer tabId, object details, function callback)
