Uncaught SyntaxError: Unexpected string

column = '<div id="column" style="left:0%;" class="col-md-4 slide-in-demo">

So you’re trying to set column to a multi-line value, which you can do, but you need to do so differently. Wrap the string in backticks, rather than quotes, turning it into a “string literal”. That will allow it to be multi-line and all kinds of other neat juju.
