When the information you wanna access from a particular webpage is only a little bit further down the page from where you are. This means that it is close enough for you to be bothered enough to scroll down the page and access it quickly. It is therefore said to be 'within scrolling distance'
"I can't see where to type in my email address"
"That's because it's further down the page, but don't worry, it's within scrolling distance"
