Responsive summary component with import of data to populate content

I had a lot of fun with this one, especially with the importing of the content data. I'm still working on matching the design perfectly.

• How do people assess how close your font sizing, font spacing, font weights, letter spacing, etc. are to the original if just using the JPG design files? Any tricks? I'm using the Perfect Pixel chrome extension, but still feel like it's a challenge.
• How do people assess the box shading? Any good tools or blog posts on learning about the box shading parameters and how to match what's in the design?
