Is it possible to change CSS gradients randomly every time the page is refreshed?

Question

Is it possible to change CSS gradients randomly every time the page is refreshed?

Is there a way to randomly cycle CSS gradients each time the page is reloaded?

I have defined the following CSS gradients that I want to use:

/* Purple */
.fp-hero {
    background: linear-gradient(20deg, #6e48aa 0%, #9d50bb 73%, #b176cc 100%);
}

/* Light Blue */
.fp-hero {
    background: linear-gradient(20deg, #1fa2ff 0%, #12d8fa 73%, #a6ffcb 100%);
}

/* Green */
.fp-hero {
    background: linear-gradient(20deg, #56ab2f 0%, #a8e063 73%, #dce356 100%);
}

/* Tangerine */
.fp-hero {
    background: linear-gradient(20deg, #db5041 0%, #ff7566 73%, #fe8a5b 100%);
}

If anyone has any tips or suggestions, please let me know. Thank you.

It seems like you grasp the reason why your current setup is not functioning as expected, but let me elaborate. By consistently using the same selector and properties, each subsequent selection will overwrite the previous one, resulting in always ending up with the color "Tangerine".

To resolve this issue, I recommend modifying the classes to include a secondary class name and then randomly assigning that color class upon page load. This approach enables you to target multiple elements on the page and ensure they are coordinated.

For instance (click "Run Code Snippet" to observe it cycle):

$( document ).ready(function() {
    var colors = [
      "purple",
      "blue",
      "green",
      "orange"
    ];
    var randomIndex = Math.floor(Math.random() * colors.length);
    $(".fp-hero").addClass(colors[randomIndex]);
});

/* Purple */
.fp-hero.purple {
    background: linear-gradient(20deg, #6e48aa 0%, #9d50bb 73%, #b176cc 100%);
}

/* Light Blue */
.fp-hero.blue {
    background: linear-gradient(20deg, #1fa2ff 0%, #12d8fa 73%, #a6ffcb 100%);
}

/* Green */
.fp-hero.green {
    background: linear-gradient(20deg, #56ab2f 0%, #a8e063 73%, #dce356 100%);
}

/* Tangerine */
.fp-hero.orange {
    background: linear-gradient(20deg, #db5041 0%, #ff7566 73%, #fe8a5b 100%);
}

<div class="fp-hero">
  This is my element
</div>

Answer №2

To begin, it seems that you have 4 CSS classes all named .fp-hero. The last one's background property (/* Tangerine */) takes precedence over the previous ones.

If I understand correctly, my suggestion would be to give them unique names like

.fp-hero-purple, .fp-hero-light-blue

, and so forth. This way, you can manipulate your target elements' CSS classes with JavaScript and switch between them as needed.

If you prefer not to use JavaScript, consider exploring keyframes: https://www.w3schools.com/cssref/css3_pr_animation-keyframes.asp

Update: Apologies for missing the "random" aspect earlier; in this case, keyframes may not work for achieving randomness. It seems you are looking to cycle through different gradients.
