I'm a student and the textbook I'm using is telling me to create a button by just making a link (<a href="myhome.html">Sign Up</a>) then styling it with CSS. It's affecting all of the links on every page, and even the navigation bar. The textbook was written when HTML5 was brand new.
The website I am working on is 5 pages, mainpage, myhome, forums, signup, and login. The only pages I need buttons on is signup and login, and both of those are supposed to go to myhome.
How do I make a button that I can format with CSS without it affecting every link on the website and the navigation bar?
Thank you
