Setting Up the HTML

First, we'll need some basic HTML to create the button element. Here's a simple structure:

<a href="#"><span>Button</span></a>

This code creates a button with the class "rgb-button". We'll use this class in our CSS to target the button for styling and animation.

Building the CSS Animation

Now comes the fun part: creating the animation! Here's the CSS code that will make the magic happen:

a{
    position: relative;
    width: 160px;
    height: 50px;
    line-height: 48px;
    background: #000;
    text-transform: uppercase;
    font-size: 20px;
    letter-spacing: 4px;
    text-decoration: none;
    -webkit-box-reflect: below 1px -webkit-       
    linear-gradient(transparent, #0004);
}

a::before{
    content: '';
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background: linear-gradient(45deg, #fb0094, #00f, #0f0, 
    #ff0, #f00, #fb0094, #00f, #0f0, #ff0, #f00);
    background-size: 400%;
    opacity: 0;
    filter: blur(20px);
    transition: 0.5s;
}
a::after{
    content: '';
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background: linear-gradient(45deg, #fb0094, #00f, #0f0, 
    #ff0, #f00, #fb0094, #00f, #0f0, #ff0, #f00);
    background-size: 400%;
    opacity: 0;
    transition: 0.5s;
}

a:hover::before,
a:hover::after{
    opacity: 1;
    animation: animate 20s linear infinite;
}

@keyframes animate{
    0%{
        background-position: 0 0;
    }
    50%{
        background-position: 300% 0;
    }
    100%{
        background-position: 0 0;
    }
}

a span{
    position: absolute;
    display: block;
    top: 1px;
    left: 1px;
    right: 1px;
    bottom: 1px;
    text-align: center;
    background: #0c0c0c;
    color: rgba(255, 255, 255, 0.2);
    transition: 0.5s;
    z-index: 1;
}

With these steps, you can easily implement RGB button animations on your website and create an engaging user interface that stands out from the crowd.
