Customized CSS for smartphones and tablets

My CSS code currently looks like this:

#FSBDiv-Inner {
    position: fixed;
    top: 20%;
    left: 25%;
    width: 50%;
    z-index: 999;
    display: flex;
    justify-content: center;
    background-color: white;    
}

However, for mobile devices, I need to adjust it to the following:

#FSBDiv-Inner {
    position: fixed;
    top: 20%;
    width: 100%; 
    z-index: 999;
    display: flex;
    justify-content: center;
    background-color: white;    
}

Can anyone guide me on how to make these changes dynamically based on screen resolution?

Answer №1

Typically, css targeting specific selectors (like screen width) is implemented using the @media rule.

Using a scenario where we only want the rule to affect screens with a width less than 400px, here is an example of the code.

@media only screen and (max-device-width: 400px) {

  #FSBDiv-Inner {
      position: fixed;
      top: 20%;
      width: 100%; 
      z-index: 999;
      display: flex;
      justify-content: center;
      background-color: white; 
   }

}

To delve deeper into the @media rule, it would be beneficial to refer to the documentation ( https://developer.mozilla.org/en-US/docs/Web/CSS/@media ) (as there are various important considerations such as screen orientation, like landscape or portrait).

Answer №3

Creating a responsive design for mobile devices is essential for providing a good user experience. One way to achieve this is by using Bootstrap, which offers a variety of tools such as containers, rows, and columns that can help make your website mobile-friendly.
