How to apply style to the variable in javascript

// creating an empty object to hold functionality of our app
var app = {};


// create an init method that will hold all the code that must run upon initialization of app
app.init = function(){
    $('#subject').on('keyup', function(){
  var subject = $(this).val().toLowerCase();
  //empty before we ask for result that were there so new results will show up
  $('#showresults').empty();
  app.getShow(subject);
});
};

// getShow method will make the Ajax request to the API
app.getShow = function(query){
    $.ajax({
        url: 'http://api.tvmaze.com/search/shows?q=:query',
        method: 'GET',
        dataType: 'json',
        data: {
            ps: 20,
            q: query,
            format: 'json'
        },
        success: function(results){
            console.log(results);
            app.displayShow(results);
        },
        error: function(error){
            console.log(error);
        }
    });
};



// displayShow will inject our art pieces into the DOM
app.displayShow = function(ShowArray){
    //forEach is the equivalent of for loop in jQuery. it is used to loop over our array of show
    ShowArray.forEach(function(showObject){
      //create a variable that will hold the html and the h that doesn't exist yet. we use artPiece.title because it's the place holder for the object
        var title = showObject.show.name  ;
        var country = showObject.show.network.country.name
        var status= showObject.show.status ;
        var summary =  showObject.show.summary ;
        //Adding all of our elements into this div

        var showHtml = $('
').addClass('series').append(title + '
' + country + '
' + status + summary);
        $('#showresults').append(showHtml);
    });
};


$(function(){ // shortform of document.ready, which waits for all of the HTML document to be loaded before ruing JS
    app.init();
});
