How to move form from center to right



I am working on this login/signup form on CodeIgniter. Got this login/signup code from the internet, but by default, it is in the center. So how do I move this form to the right side of the page? enter image description here

Answer

add float: right to your content. In your css change form class as below

 .form {
    float: right;
  background: rgba(19, 35, 47, 0.9);
  padding: 40px;
  max-width: 600px;
  margin: 40px auto;
  border-radius: 4px;
  box-shadow: 0 4px 10px 4px rgba(19, 35, 47, 0.3);
    margin-right: 20px; /*what ever you want*/
}
