Use page.onResourceRequested, as in example loadurlwithoutcss.js:

page.onResourceRequested = function(requestData, request) {
    if ((/http:\/\/.+?\.css/gi).test(requestData['url']) || 
            requestData.headers['Content-Type'] == 'text/css') {
        console.log('The url of the request is matching. Aborting: ' + requestData['url']);
        request.abort();
    }
};
