Do you want to add an eye-catching continuously animated RGB border to a circle on your website? With just a few lines of CSS, you can achieve this stunning visual effect. Let's get started!

Step 1: Setting Up the HTML

Start by creating the basic HTML structure:

<!DOCTYPE html>
<html>
<head>
    <title>Continuously Animated RGB Border</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <div class="circle"></div>
</body>
</html>

Step 2: Adding the CSS

Next, add the CSS styles to create the continuously animated RGB border:

/* styles.css */
body {
    font-family: Arial, sans-serif;
    line-height: 1.6;
    padding: 20px;
}

.circle {
    width: 200px;
    height: 200px;
    border-radius: 50%;
    border: 5px solid;
    background-color: #f0f0f0;
    animation: rotateBorder 3s linear infinite;
}

@keyframes rotateBorder {
    0% {
        border-color: red;
    }
    33% {
        border-color: green;
    }
    66% {
        border-color: blue;
    }
    100% {
        border-color: red;
    }
}

p {
    font-size: 18px;
    margin-bottom: 20px;
}

.tip {
    font-weight: bold;
}

Step 3: Explanation

Let's break down the CSS code:

  • We define a div with the class "circle" to create the circle element.
  • The circle has a width and height of 200px, and we set the border radius to 50% to make it a perfect circle.
  • The border is initially set to a 5px solid color (#f0f0f0) to create a white circle with a gray border.
  • We use the @keyframes rule to define the animation called "rotateBorder."
  • In the keyframes, we specify the border color at different percentage intervals (0%, 33%, 66%, and 100%) to create the RGB effect. The border will transition from red to green to blue and then back to red.
  • The animation "rotateBorder" lasts for 3 seconds and repeats infinitely (infinite).

Step 4: Apply to Your Website

Now that you have created the continuously animated RGB border for a circle, you can apply it to any element on your website. Add the "circle" class to the element, and it will inherit the animation effect. Experiment with different sizes and colors to match your website's design.

Conclusion

Creating a continuously animated RGB border for a circle is a simple yet visually appealing technique to add dynamic elements to your website. The CSS animation allows you to bring your designs to life and engage your visitors with captivating visuals.

So, go ahead and add some animated flair to your website with this cool RGB border animation!
