This is a nice little neon glow border style that can be used on elements in a page to draw attention and its not too much code involved. It can be tweaked in loads of different ways to give some real interesting designs.
The css:
.gradient-border {
display: flex;
flex-flow: column;
align-items: center;
justify-content: center;
width: 600px;
min-height: 300px;
color: white;
padding: 1.8em;
margin-top: 5em;
}
.gradient-border {
--borderWidth: 2px;
--borderRadius: 20px;
background: var(--bg-color);
position: relative;
border-radius: var(--borderRadius);
}
.gradient-border:after {
content: '';
position: absolute;
top: calc(-1 * var(--borderWidth));
left: calc(-1 * var(--borderWidth));
height: calc(100% + var(--borderWidth) * 2);
width: calc(100% + var(--borderWidth) * 2);
background: linear-gradient(60deg, #f79533, #f37055, #ef4e7b, #a166ab, #5073b8, #1098ad, #07b39b, #6fba82);
border-radius: var(--borderRadius);
z-index: -1;
animation: animatedgradient 3s ease alternate infinite;
background-size: 300% 300%;
filter: blur(10px);
}
@keyframes animatedgradient {
0% {
background-position: 0% 50%;
}
50% {
background-position: 100% 50%;
}
100% {
background-position: 0% 50%;
}
}The html:
<div class="gradient-border">
<p>Box with glowing neon edge</p>
</div>
