On my website, the title of each page fills the entire screen before the content appears when you scroll down. I am interested in adding a smooth automatic scroll feature that will transition to the next section after about half a second on the initial "title screen". You can experience this effect by visiting this page.
The content is identified by the class name contactus, but I created a specific class called scroll-down for the scrolling functionality that I want to use across multiple sections of the site.
