wp-login-box

Being very new to developing in wordpress it was difficult trying to make my own inline login form into the menu bar. It worked perfectly where I wanted it to which rarely works out with most plugins. Very underestimated! I do have one question: How can I hook it to my styles.php using CSS? Example style in style.css: .top-login { margin-left:350px; padding: 0px; } .top-login p { margin-bottom: 15px; color: #e00000; } input { display:inline; } All I’m looking to know here is what would I replace the .top-login with to hook it with my login form? What would I call the form in this area.
