Remove textarea's box shadow on bottom only - html

Question

This is what I currently have:
What I'm trying to do is remove the bottom box-shadow of the textarea (the one just above the B, I, and U) so that it ends up looking like this:
Here's the JSFiddle: http://jsfiddle.net/MgcDU/7616/
HTML:
<div class="editor span4">
<textarea class="span4"></textarea>
<ul class="format-post">
<li><b>B</b></li>
<li><i>I</i></li>
<li><u>U</u></li>
</ul>
</div>
CSS:
#import url('http://getbootstrap.com/2.3.2/assets/css/bootstrap.css');
body {
margin: 10px;
}
textarea {
border-radius: 2px 2px 0 0;
border-bottom-color: #eee;
}
textarea:focus {
border-bottom-color: #eeeeee;
}
textarea:focus + .format-post {
border-color: rgba(82, 168, 236, 0.8);
box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 7px rgba(82, 168, 236, 0.6);
transition: border 0.2s linear 0s, box-shadow 0.2s linear 0s;
}
.format-post {
list-style: none;
background: #fafafa;
height: 35px;
border: 1px solid #cccccc;
border-top: 0;
border-radius: 0 0 2px 2px;
margin: 0;
margin-top: -10px;
}
.format-post li {
width: 35px;
height: 35px;
border-right: 1px solid #eee;
text-align: center;
line-height: 33px;
font-size: 14px;
color: #333;
cursor: pointer;
display: inline-block;
}
Please help.

Answer 1

I just changed the box-shadow to
box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075),
0 -4px 7px rgba(82, 168, 236, 0.6);
and it worked! :)
The bottom color was still blue, so I just changed it to
border-bottom: 1px solid #999;
You can change it if needed! :)

Pardon me, I just saw that you want the textarea to be colored, which doesn't fit for the question. You're saying in title to remove the border-bottom. But in answer you're having bottom border for both.
If you want to get the border and all animation when textarea is not active, then remove :focus and it will do the job.
And I am still very sorry, for unclear answer because I am not able to get it, which should be answered the question or the answer.
