Flat Button makes it easy to create a well-designed button that can be used as a call to action on your website. Buttons are much more effective at converting your visitors into leads or customers, opposed to text or image links.

Call to Action grabs your visitor's attention and prompts them to take some action: sign-up on your email list, receive a promotional discount, take advantage of an offer, etc. It does this in combination with a variety of other stacks in order to display the call to action in a modal or pop-up window, slider, or other similar function. You've likely seen this at work on other websites, and if done well can be a highly effective way of achieving a goal for your website.
