Has anyone encountered a jQuery script that can automatically navigate to a specific point on a website when you scroll past a certain area? For example, consider this single-page site with 4 full-size divs (http://www.bettondesignwork.co.uk/sierragrande). When scrolling so that the bottom of one div and the top of another are both visible, the script should align the most visible div at the center of the page.
I am not very familiar with jQuery and unsure where to even start with this. Any insights or tips would be greatly appreciated!
