Imagine you have the following code:
<div class="row-fluid">
<div class="span6"></div><!--span6 END-->
<div class="span6"></div><!--span6 END-->
</div><!--row END-->
Now envision two red boxes, each taking up 50% of the screen. However, every time this setup is implemented, there seems to be a margin above and in between the spans and rows. How can this issue be addressed so that there is no margin above or between the spans? The goal is for them to touch at the top and sides seamlessly.
