Instead of tiptoeing around the issue, let me just be blunt and ask:
I'm curious about how they created this image header. Even after removing all javascript code and css using Chrome's property inspector, the image continued to stretch. The style within the element adjusts based on window size. I suspect there is an event listener at play, but I can't seem to locate it.
If anyone can shed some light on this, I would greatly appreciate it. Thank you.
