using CSS Flex tried my best

Hello Enis67 👋. Congratulations on successfully completing the challenge! 🎉 I have other recommendations regarding your code that I believe will be of great interest to you.

Try to do that :

HTML :

<div class="hiding">
    <img src="images/image-equilibrium.jpg" alt="image-equilibrium">
    <div class="background">
      <img class="hide" src="images/icon-view.svg" alt="icon-view">
    </div>
  </div>

CSS :

.hiding{
	position: relative;
	border-radius: 0.8rem;
}
.background{
	position: absolute;
	height: 99%;
	width: 100%;
	top: 0;
	background: hsla(178.1, 100%, 50%, 0.47);
	border-radius: 0.8rem;
	display: flex;
	align-items: center;
	justify-content: center;
	opacity : 0;
}
.background:hover{
	opacity: 1;
}
.hide {
  /*All removed*/
}

I have'nt tested before sent you.
