Show only half of SVG

I'm showing my SVG image in the card

  <div class="card-image">
    <img src="/images/linux.svg" />
  </div>

I couldn't upload the SVG file here, but what I'd like to do is: (After an event is triggered)

Can someone point me to the right direction?

Solution

  • You can set a pseudo element on the container, and set a gradient to this pseudoelement that is transparent for half of it, a gray for the other half. The linear gradient can be set at the angle the you want

    .card-image {
    width: 200px;
    height: 300px;
    display: inline-block;
    position: relative;
}

.grayed:after {
    content: "";
    position: absolute;
    width: 100%; 
    height: 100%;
    left: 0;
    z-index: 9;
    background-image: linear-gradient(110deg, transparent 50%, #888a 50%);

}
    <div class="card-image">
    <img src="https://dummyimage.com/200/300/ff00ff" />
</div>
<div class="card-image grayed">
    <img src="http://placekitten.com/200/300/808080" />
</div>

    .card-image {
    width: 600px;
    height: 400px;
    display: inline-block;
    position: relative;
    overflow: hidden;
}

.grayed:after {
    content: "";
    position: absolute;
    width: 200%; 
    height: 200%;
    left: 50%;
    top: -50%;
    z-index: 9;
    background-color: white;
    mix-blend-mode: color;
    transform: rotate(30deg);
    transform-origin: left center;
    animation: rotate infinite 10s linear;
}

@keyframes rotate {
    from {     transform: rotate(0deg);}
    to {     transform: rotate(360deg);}

}
    <div class="card-image grayed">
    <img src="https://dummyimage.com/600/400/ff00ff" />
</div>
