css - Two Divs next to each other, that then stack with responsive change

Question

I'm trying to achieve something that I am sure should be easier than I am making it!

I am using the Skeleton responsive framework, and have been fine up until now.

Here is a diagram of what I want to achieve.

This will be placed within a column. Once that columns reduces in size, I would like it to stack the divs as per the second example in the diagram. I've tried a few different ways, but keep getting it wrong.

I am pretty new to HTML/CSS so any help is appreciated! Many thanks!

You can use CSS3 media query for this. Write like this:

CSS

.wrapper { 
  border : 2px solid #000; 
  overflow:hidden;
}

.wrapper div {
   min-height: 200px;
   padding: 10px;
}
#one {
  background-color: gray;
  float:left; 
  margin-right:20px;
  width:140px;
  border-right:2px solid #000;
}
#two { 
  background-color: white;
  overflow:hidden;
  margin:10px;
  border:2px dashed #ccc;
  min-height:170px;
}

@media screen and (max-width: 400px) {
   #one { 
    float: none;
    margin-right:0;
    width:auto;
    border:0;
    border-bottom:2px solid #000;    
  }
}

HTML

<div class="wrapper">
    <div id="one">one</div>
    <div id="two">two</div>
</div>
