which renders as follows
As you can see at the bottom I have a triangle which I'm trying to position so it overflows on to the next box, unfortunately I can not for the life of me get it to sit correctly, i.e the white space between the dark shade and lighter shade of gray to dis-appear can someone give me a hand please the end result is to look like this :

Answer 1

First of all it is recommended not to use tables for formatting page sections. In this case you can set the Parent of triangle as a relative positioned element with height of 0px and position triangle as absolute element. So:
<div class="deviceWidth" style="width:580px;position:relative;height:0;margin-right:auto;margin-left:auto;">
<img width="20" src="http://res.cloudinary.com/dncu6pqpm/image/upload/v1428628617/triangle_C5C5C5_ks8sg2.jpg" alt="" style="border:0;position:absolute;top:0;right:20px;border-radius: 0px; width: 20px;" class="deviceWidth">
</div>
also please note that :
remove the display:block from image
set border:0 inside styles not as a separate attribute
I have added margin-right:auto and margin-left:-auto to align div in center of screen
