Problems with margins on div's and images

[OM2]

I want zero space between div's and images
I've tried everything, nothing works!
I was hoping someone could point out where I was going wrong

I have this code:

	<div style="width:100&#37;;margin-top:0;margin-bottom:0;padding-top:0;padding-bottom:0"><a href="c.html"><img src="images/london-bridge.jpg" alt="Ferrari Car" style="width:100%;margin-top:0;margin-bottom:0;padding-top:0;padding-bottom:0"></a></div>
		<div style="clear: both;"></div>
	  <div style="width:40%;float:left;margin-top:0;margin-bottom:0;padding-top:0;padding-bottom:0"><a href="c.html"><img src="images/1.jpg" alt="Ferrari Car" style="width:100%;margin-top:0;margin-bottom:0;padding-top:0;padding-bottom:0"></a></div>
	  <div style="width:60%;float:left;margin-top:0;margin-bottom:0;padding-top:0;padding-bottom:0"><a href="d.html"><img src="images/2.jpg" alt="Porsche Car" style="width:100%;margin-top:0;margin-bottom:0;padding-top:0;padding-bottom:0"></a></div>
		<div style="clear: both;"></div>
	  <div style="width:30%;float:left;margin-top:0;margin-bottom:0;padding-top:0;padding-bottom:0"><a href="a.html"><img src="images/bmw.jpg" alt="BMW Car" style="width:100%;margin-top:0;margin-bottom:0;padding-top:0;padding-bottom:0"></a></div>
	  <div style="width:70%;float:left;margin-top:0;margin-bottom:0;padding-top:0;padding-bottom:0"><a href="b.html"><img src="images/bmw2.jpg" alt="BMW 2 Car" style="width:100%;position:relative;left:1px;margin-top:0;margin-bottom:0;padding-top:0;padding-bottom:0"></a></div>

This image shows what I get:

I should explain why I have done this way and why the image widths are set to be 100% width

The code is for a mobile website and I need the images to stretch all way across the screen - regardless of device or orientation

ONE MORE PROBLEM: the single image at the top goes all the way across - this is fine.
BUT, below this, I have 2 images side by side - the right hand image ALWAYS sits 1 pixel away from the right edge!
Grrrr!!!!
This is why I have added: position:relative;left:1px;

Where am I going wrong?

Thanks
