Creating a metallic effect with CSS

Hey! I'm back today with another CSS trick. This time with something that look like from the past, kind of old school. But as we know everything old is new again, so let's see how to create a metallic effect with CSS.


For what we have below, the code is pretty simple. We have a button with a gradient background.

<button class="metallic-button">Download</button>

.metallic-button {
font-size: 14px;
padding: 6px 16px;
font-weight: 400;
border: none;
outline: none;
color: #000;
background: linear-gradient(
#999 5%,
#fff 10%,
#ccc 30%,
#ddd 50%,
#ccc 70%,
#fff 80%,
#999 95%
text-shadow: 1px 1px 2px rgba(255, 255, 255, 0.5);
border-radius: 10px;
box-shadow: 0 2px 5px rgba(0, 0, 0, 0.3);
cursor: pointer;
transition: all 0.2s ease-in-out;
.metallic-button:hover {
transform: translateY(-2px);

The trick here is to use a gradient background with a lot of stops. The gradient is made of 7 colors, 3 dark and 3 light, and one in the middle that is the same as the background. The gradient is at 45deg, so the light colors are on the top left and the dark ones on the bottom right.


You can play with some different gradients or colors. I kind of like them, they are kitsh but fun.


Another thing, we can associate it with a shine effect. You can hover the card to see the effect.

With this CSS:

.card-shine-effect-metal {
--shine-deg: 45deg;
position: relative;
overflow: hidden;
border-radius: 0.875rem;
padding: 4rem 2rem;
box-shadow: 0 25px 50px -12px rgba(0, 0, 0, 0.15);
width: 200px;
height: 180px;
background: linear-gradient(to bottom, #dbdbdb, #f9f9f9, #dbdbdb);
.card-shine-effect-metal:after {
content: "";
top: 0;
transform: translateX(100%) rotate(var(--shine-deg));
width: 300%;
height: 300%;
position: absolute;
z-index: 1;
background: linear-gradient(
transparent 20%,
transparent 40%,
rgb(255, 255, 255, 0.4) 50%,
rgb(255, 255, 255, 0.4) 55%,
transparent 70%,
transparent 100%
transition: transform 2s ease-in;
transform: translateX(100%) rotate(var(--shine-deg));
.card-shine-effect-metal:hover:after {
animation: shine 1s infinite ease-in;
@-webkit-keyframes shine {
0% {
transform: translateX(100%) rotate(var(--shine-deg));
100% {
transform: translateX(-100%) rotate(var(--shine-deg));

For the shine effect, we use a pseudo element with a gradient background. (not the same technique as my previous post)

It's fun to explore some old school effects and see how we can recreate them. It can be something I can do more. Hope you like it, see you next time!
