i am thinking of doing something like a long vertical scrolling portfolio. i have a few categories that i want to use as the navigation items. eg. web design, digital art etc.
so i need a way of detecting if i have past, say web design and into digital art. but not yet into the next category say logo design. how can i do this? i am thinking i will have anchors for the categories. i want to use jQuery to detect whats the category thats visible to the user. tho there maybe chance that more that 1 category is visible.
