inputText component not showing in HTML5 Canvas application

I have added an inputText component to my application. When I first created my application, published it, and ran the html file, it appeared just fine. For some reason, it no longer appears. Any ideas why?

It has the default parameters of value blank, disabled unchecked, visible checked, and class ui-textinput.

The only code related to it is

$("#inputNumber").css({

        "color": "teal",

        "font-size": 42,

        "text-align": "center"

    });

Thanks
