I have a basic web page layout with a 100% width header and a sticky footer. In between the two I have a large graphic.
I would like the graphic to resize dynamicall
This will resize your image to match your container and keep the ratio in place. If you set the container to a percentage everything will scale.
wrapper width = 960px divided by screen width = 1640px
If you want the entire site to be responsive you have to do the math all the way down. divide the child by it's parent. Hope this helps!
