Should I style links as buttons?
But for accessibility purposes, it's important to style buttons as buttons and links as links. So if the app's CTA only takes the user to a new page, use a link instead. Performs an action, like submitting a form. Button summons a popup or modal, or changes elements of the website.
What makes button as a link useful?
Even without JavaScript, button elements can be triggered by the Space and Enter keys on a keyboard. That's part of what makes them such appealing and useful elements: they are discoverable, focusable, and interactive with assistive technology in a predictable way.
