3 Column Preview Card Solution

Hello Umutcan Kocamış Great Job!

I would like to suggest a solution. Begin by setting a transparent border for each button initially. Upon hover, apply the desired color and adjust the border accordingly

.sedans .learn-more {
        color: hsl(31, 77%, 52%);
        border: 1px solid transparent;  // give it initially transparent border
} 


.sedans .learn-more:hover {
  border-color: hsl(0, 0%, 95%);  // give it the desired colored border on hover 
  color: hsl(0, 0%, 95%);
  background-color: hsl(31, 77%, 52%);
}
