I’m not quite sure what happened. I replaced jquery, jquery-ui, jquery-validate (not jquery.validate.unobtrusive), and modernizr. I updated the files to: 1.8.1, 1.8.23, 1.8.1, and 2.6.2, respectively. I’ve updated the _Layout.cshtml file to reflect the changes as well. And the CSS broke. So then, I replaced the CSS and Images in the Content folder and replaced them with the new JQuery UI stuff. Still broken. When I say broken I mean the gray background of the body is gone. The whole page color is blue. Except the tabs (those background color is still gray). Also, my divs no longer float to the left. They just render one under the other.
So, what did I do wrong?
It seems that the script that Modernizr generated started like this:
;window.Modernizr = function (a, b, c). Once I removed the;, it worked fine.
