I successfully created a new app on Openshift and the default template is functioning well. The only customization I made was:
<head>
...
<link href="styles.css" rel="stylesheet">
</head>
and placed a file named styles.css in the same directory as index.html. In the CSS file, I simply changed the footer to red. When I view index.html in my browser, the changes are visible, but once I upload the files to Openshift, nothing updates and I encounter the following error:
GET http://bgl-boardgamelab.rhcloud.com/styles.css 404 (Not Found)
I believe I'm missing something simple, but I can't seem to pinpoint what it is.
