A link can be styled to look like a large blue button which can appear anywhere on the main body of the page. A button style link looks like this:
We advise using the Button style judiciously, for primary actions you want your visitor to take, such as Buy Tickets or Register Now.
Step-by-step guide to Add a Button Style to a Link
In the Drupal Body editing area, create a link. See Create a Link. You cannot add Button style to plain unlinked text.
Highlight the link in the body, then choose Button from the Style menu on the Object Styles section. If you want a slightly smaller blue button, choose Small Button.
The Button-styled link will have a gray box around it, to confirm that the Button style is applied to it.
Click Save and Preview to view your completed Button link.
