For some reason, bootstrap is only allowing me to use the "col-sm" class. If I enter anything else into my code, including the "xs" class, the columns are stacked on top of one another. This is my code:
<div class="container-fluid">
<div class="row">
<div class="col-xs-9">
<div class="well">something here</div>
</div>
<div class="col-xs-3">
<div class="well">something here</div>
</div>
</div>
</div>
I have ensured that the appropriate CSS, JS, and jQuery files are linked (hence why the "col-sm" class works), and only have my own personal CSS style-sheet linked in addition to them (which does not predefine any width or height for any element). Furthermore, I am viewing my work on the latest version of Mozilla Firefox.
Edit: I have closed the div with the class "fluid-container", it still produces the same problem. That is, instead of the two columns appearing on the same row, the two columns are stacked on top of one another. For some reason, the only class that works is "col-sm"--any other class, including the "xs", just lines the columns atop of one another.
