# Buttons

The button module in buildy has a hidden feature that you probably are not aware of.

# ID as button URL

You can use the page or post ID of whatever you're linking to as the button URL in buildy. This extends to blurb buttons as well.

Use the page or post ID as the button URL

# Why not just use a relative path?

You can use a relative path e.g:

Button with a relative URL

But a good reason not to use relative URL's is that if the page slug is ever changed.. E.g "contact-us" instead of "contact" there is a chance the link will 404.

With the ID, even if the page title/slug are changed, the link will remain working.
