How to create a div with a diagonal (or angled) top line
I'm a newbie on CSS3 and all I know is self-learned, reading you guys or any other tutorials so after hours of researching and trial-error, I could really use your help :(.
I'm trying to rotate JUST the top line of a div. This is what I did so far:

On the footer, I have rotate two divs to create that effect. But what I want to do is to have a straight bottom line on the green div. This is an example of how I would like it to be:

I don't know if I'm explaining myself right. This is the CSS code I've used to rotate the divs:
#footer-top {
color: #fff;
padding: 35px 0 15px;
transform: rotate(2deg) scale(1) skew(3deg) translate(0px);-webkit-transform: rotate(2deg) scale(1) skew(3deg) translate(0px);-moz-transform: rotate(2deg) scale(1) skew(3deg) translate(0px);-o-transform: rotate(2deg) scale(1) skew(3deg) translate(0px);-ms-transform: rotate(2deg) scale(1) skew(3deg) translate(0px);
}
#footer-space {
padding: 0 0 6px;
}
#footer-top2 {
color: #fff;
background-color: rgba(20, 122, 188, 0.5);
background: rgba(20, 122, 188, 0.5);
color: rgba(20, 122, 188, 0.5);
padding: 6px 0 12px;
height: 2px;
transform: rotate(358deg) scale(1) skew(0deg) translate(0px);-webkit-transform: rotate(358deg) scale(1) skew(0deg) translate(0px);-moz-transform: rotate(358deg) scale(1) skew(0deg) translate(0px);-o-transform: rotate(358deg) scale(1) skew(0deg) translate(0px);-ms-transform: rotate(358deg) scale(1) skew(0deg) translate(0px);
}
#footer-top3 {
color: #fff;
background-color: rgba(128, 185, 46, 0.7);
background: rgba(128, 185, 46, 0.7);
color: rgba(128, 185, 46, 0.7);
transform: rotate(358deg) scale(1) skew(-2deg) translate(0px);
-webkit-transform: rotate(358deg) scale(1) skew(-2deg) translate(0px);
-moz-transform: rotate(358deg) scale(1) skew(-2deg) translate(0px);
-o-transform: rotate(358deg) scale(1) skew(-2deg) translate(0px);
-ms-transform: rotate(358deg) scale(1) skew(-2deg) translate(0px);
}
And this is the HTML:
<div id="footer-top2"></div>
<div id="footer-space"></div>
<div id="footer-top3">
<div id="footer-top">
<div class="container clearfix">
<div class="one-fourth">
<div class="widget twitter-widget">
<h3>Últimos Tweets</h3>
<div class="tweet"></div>
</div>
</div>
<div class="one-fourth">
<div class="widget twitter-widget">
<h3> Facebook Feed</h3>
<div class="tweet"></div>
</div>
</div>
<div class="one-fourth">
<div class="widget twitter-widget">
<h3>Fotos en Instagram</h3>
<div class="tweet"></div>
</div>
</div>
<div class="one-fourth column-last">
<div class="widget contact-info">
<h3>Contacto</h3>
<div>address here
</div>
</div>
</div>
</div>
</div>
</div>
If any of you could help me I will be very grateful!!
Thanks in advance.

First I thought this could be done with CSS triangles, but I can't quite work out how to make a downward right pointing triangle be 100% width, so I moved on to another option...
You could keep using the rotation technique as you are doing, but then add some padding to the bottom of the green part, and then use a negative margin-bottom to bring the footer back up and over the diagonal. If you then set the footer to relative, it should sit over the top of the green so you won't see the diagonal line.
I tested this on the actual site and found that I need to add the padding to the container inside footer-top and put the negative margin on footer-top. Otherwise, the padding would cause a gap at the bottom of the body.
Hard to describe in words, so here's the snippet.
#footer-top {
color: #fff;
padding: 35px 0 15px;
transform: rotate(2deg) scale(1) skew(3deg) translate(0px);-webkit-transform: rotate(2deg) scale(1) skew(3deg) translate(0px);-moz-transform: rotate(2deg) scale(1) skew(3deg) translate(0px);-o-transform: rotate(2deg) scale(1) skew(3deg) translate(0px);-ms-transform: rotate(2deg) scale(1) skew(3deg) translate(0px);
margin-bottom: -20px; /* Added */
}
/* Added */
#footer-top .container {
padding-bottom: 20px;
}
#footer-space {
padding: 0 0 6px;
}
#footer-top2 {
color: #fff;
background-color: rgba(20, 122, 188, 0.5);
background: rgba(20, 122, 188, 0.5);
color: rgba(20, 122, 188, 0.5);
padding: 6px 0 12px;
height: 2px;
transform: rotate(358deg) scale(1) skew(0deg) translate(0px);-webkit-transform: rotate(358deg) scale(1) skew(0deg) translate(0px);-moz-transform: rotate(358deg) scale(1) skew(0deg) translate(0px);-o-transform: rotate(358deg) scale(1) skew(0deg) translate(0px);-ms-transform: rotate(358deg) scale(1) skew(0deg) translate(0px);
}
#footer-top3 {
color: #fff;
background-color: rgba(128, 185, 46, 0.7);
background: rgba(128, 185, 46, 0.7);
color: rgba(128, 185, 46, 0.7);
transform: rotate(358deg) scale(1) skew(-2deg) translate(0px);
-webkit-transform: rotate(358deg) scale(1) skew(-2deg) translate(0px);
-moz-transform: rotate(358deg) scale(1) skew(-2deg) translate(0px);
-o-transform: rotate(358deg) scale(1) skew(-2deg) translate(0px);
-ms-transform: rotate(358deg) scale(1) skew(-2deg) translate(0px);
}
#footer-bottom {
color: #808080;
background-color: #2D2D2D;
font-size: 0.916em;
padding: 30px 0;
border-top: 1px solid #000;
box-shadow: 0 4px 4px rgba(0,0,0,0.2) inset;
position: relative; /* Added */
