I want to be able to hide content when the window size is below a certain point. After finding an example at (http://css-tricks.com/dynamic-page-replacing-content/), I still couldn't figure out why it actually works.
<div class="container">
<div class="box left">foo1</div>
<aside class="box right">foo2</aside>
</div>
The objective is to hide the aside element when the width of the container falls below a specific minimum size. This should be achieved without the use of javascript, just by making adjustments in the css.
