I'm new to react and I'm trying to create a 90 degree conveyor shaped with a roller inside that have running animation (like an actual working conveyor)
So this is the example of what I've made
https://codepen.io/chococonya/pen/oNMJVGz and I need it to bend to a 90 degree shaped conveyor like in the pict below
90degree conveyor.
Code snippet:
body {
display: flex;
justify-content: center;
}
.conv {
pointer-events: auto;
cursor: pointer;
background: #e7e7e7;
border: none;
height: 100px;
width: 400px;
margin: 0;
font-family: inherit;
font-size: inherit;
position: relative;
display: inline-block;
}
.convcolor__inner {
width: fit-content;
display: flex;
position: relative;
animation: convanimate 1s linear infinite;
animation-duration: 3s;
animation-play-state: running;
opacity: 1;
}
.cvGreen {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: inherit;
overflow: hidden;
pointer-events: none;
background-image: linear-gradient( to right, #008000, #269826, #4cb04c, #6ac36a, #90db90, #a7e8a7, #c7fdc7);
}
.cvGreen span {
text-align: center;
white-space: nowrap;
color: transparent;
font-style: italic;
height: 100px;
width: 30px;
background-image: linear-gradient( to right, #008000, #269826, #4cb04c, #6ac36a, #90db90, #a7e8a7, #c7fdc7);
}
#keyframes convanimate {
0% {
transform: translate3d(calc(-50% + 1rem), 0, 0);
}
100% {
transform: translate3d(calc(-25% + 1rem), 0, 0);
}
}
<button class="conv">
<div class="cvGreen" aria-hidden="true">
<div class="convcolor__inner">
<span>.</span>
