Learn how to create an overlay effect with CSS

In this simple article you will learn how to create an overlay effect with CSS.

Overlay means to cover the surface of something with a transparent background. In other words, it is used to set one thing on the top of another.

The overlay makes a web-page attractive, Provides holds extra information for the user to take action and more so it is easy to design.

HTML - Markup
copy

<div class="overlay">
<div class="info">
<div class="close" id="closeOverlay">×</div>

<button class="btn">Subscribe</button>
</div>
</div>

CSS - Styles

Having only this code targeting the element with the overlay class will create the effect.

copy

.overlay{
	width:100%;
	height:100%;
	background-color:rgba(0,0,0,0.9);
	position:fixed;
	top:0;
	left:0;
	right:0;
	bottom:0;
	z-index:2;
	display:none;
}
	

The rest of the code I wrote was to style the layout or position of the elements I put in the inner div with the class of info.

Tutorial Code
copy
body{
}


.container{
max-width:80%;
margin:0 auto;
margin-top:20px;
}

.overlay{
width:100%;
height:100%;
background-color:rgba(0,0,0,0.9);
position:fixed;
top:0;
left:0;
right:0;
bottom:0;
z-index:2;
display:none;
}

.info{
display:flex;
flex-direction: column;
align-items: center;
justify-content: center;
height:100vh;
color:#fff;
opacity:0;
animation: channelInfo 1s ease-in 1.5s;
animation-fill-mode:forwards;
}

.info h2{
margin-bottom:0;
}

.info p{
font-size:20px;
}

.close{
position: absolute;
top:0;
right:0;
margin:20px 20px 0 0;
transform:scale(2);
transition:all 0.6s ease-in;
}

.close:hover{
color:#00796b;
cursor: pointer;
transform: scale(3) rotate(360deg);
}

.btn{
background-color:#00796b;
color:#fff;
padding:10px;
border:0;
border-radius:5px;
box-shadow: -2px 3px 4px rgba(0,0,0,0.5);
cursor: pointer;
transition: background-color 0.5s ease-in-out;
}

.btn:hover{
background-color: tomato;
}

@keyframes channelInfo{
0%{
opacity:0;
}

100%{
opacity:1;
}
}

In this next post, I will add javascript to open and close the overlay.
