Tips for creating a smooth transition between background colors within a div

Is there a way to smoothly transition between background colors within a div element?

I've been struggling with my code and couldn't find a solution. Any help would be greatly appreciated. Thanks in advance.

$(document).ready(function() {
  var containerColors = [{
      "background": "linear-gradient(to top right, #1abc9c, #3498db)"
    },
    {
      "background": "linear-gradient(to top right, red, blue)"
    }
  ];

  $("#button").click(function() {
    var random = Math.floor((Math.random() * 2));
    $("#container").css(containerColors[random]);
  });
});

#container {
  height: 100vh;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="container" class="container-fluid">
  <div class="box">
    <button id="button">click</button>
   </div>

</div>

To add a dynamic element to the background using JavaScript gradients is not currently supported, but you can achieve a similar effect with the following code:

$("#button").click(function() {
    $cont = $('#container');
    $cont.fadeOut('slow', function() {
        var random = Math.floor((Math.random() * 2));
        $("#container").css(containerColors[random]);
        $cont.fadeIn();
    });
});

For customizing the background in your CSS file, you can use the following code:

#container{
    background: linear-gradient(to top right, #1abc9c, #3498db); 
    -moz-transition: background 0.3s ease-in;
    -o-transition: background 0.3s ease-in;
    -webkit-transition: background 0.3s ease-in;
  }

By altering the background color of the container element, a smooth transition effect will be applied.

Another approach you can try is:

$(document).ready(function() {
            var containerColors = [
                {"background": "linear-gradient(to top right, #1abc9c, #3498db)"},
                {"background": "linear-gradient(to top right, red, blue)"}
            ];

            $("#button").click(function() {
                var random = Math.floor((Math.random() * 2));
                $("#container").hide();
                $("#container").fadeIn("slow", function(){
                    $("#container").css(containerColors[random]);
                });
            });
        });

I have personally tested this and it worked perfectly for me.

Animating background-gradients is not possible.

One workaround is to utilize a pseudo element and manipulate opacity, as javaScript can only interact with the DOM, excluding pseudo elements generated by CSS.

To achieve the desired effect of transitioning between two gradients, you may need an additional container specifically for this purpose:

Example:

// Update your script accordingly
$(document).ready(function() {
    var containerColors = [
        {"opacity" : "1"},
        {"opacity" : "0"}
    ];

    $("#button").click(function() {
        var random = Math.floor((Math.random() * 2));
        $("#container .bg").css(containerColors[random]);
    });
});

#container {
  position: relative;
  height: 80vh;
  background: linear-gradient(to top right, red, blue);
}

#container > .box
     /* comment:  
      or any direct child if unknown  
 #container > * 

     end comment */
{
  position: relative;
  z-index: 1;
}

#container .bg {
  background: linear-gradient(to top right, #1abc9c, #3498db);
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  transition:0.5s;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="container" class="container-fluid"><div class="bg"></div>
        <div class="box">
            <button id="button">click</button>
        </div>
    </div>
