width: 100%;
display: none;
position: fixed;
z-index: 1;
top: 0;
left: 0;
background-color: rgb(0,0,0);
background-color: rgba(0,0,0, 0.9); /* Black with a little bit see-through */
}

/* The content */
.overlay-content {
position: relative;
top: 46%;
width: 80%;
text-align: center;
margin-top: 30px;
margin: auto;
}

/* Close button */
.overlay .closebtn {
position: absolute;
top: 20px;
right: 45px;
font-size: 60px;
cursor: pointer;
color: white;
}

.overlay .closebtn:hover {
color: #ccc;
}

/* Style the search field */
.overlay input[type=text] {
padding: 15px;
font-size: 17px;
border: none;
float: left;
width: 80%;
background: white;
}

.overlay input[type=text]:hover {
background: #f1f1f1;
}

/* Style the submit button */
.overlay button {
float: left;
width: 20%;
padding: 15px;
background: #ddd;
font-size: 17px;
border: none;
cursor: pointer;
}

.overlay button:hover {
background: #bbb;
}

Step 3) Add JavaScript:

Use JavaScript to turn on and off the overlay/fullscreen effect:

Example

// Open the full screen search box
function openSearch() {
document.getElementById("myOverlay").style.display = "block";
}

// Close the full screen search box
function closeSearch() {
document.getElementById("myOverlay").style.display = "none";
}
