I'm not sure if I understand completely, but here's how to do it for what I think you mean (which would just be borders around images):
In between your <style> tags:
.border1 {border: 2px solid #color;}
.border2 {border: 1px solid #color;}
where #color is the hex value of the color you want the border to be.
then, to put it around the image, do this:
<img src="whatever.jpg" class="border1"> for the 2 pixel border
<img src="whatever.jpg" class="border2"> for the 1 pixel border
