What is difference between link and button?
UX Movement wrote an article about this, and they came up with a simple rule: Buttons are used for actions that affect the website's front-end or back-end; links are used for navigation and actions that don't affect the website at all. The line between buttons and links can be blurry.
Can links look like buttons?
Yes, it is OK to use links that look like buttons, but it is highly encouraged to use the native elements if possible. If necessary you can have links that look like buttons and you can even do the opposite and make link elements function as buttons.
