Answer 1

let drawerName = 'sideNav';
const drawerWidth = {
expanded: '100%',
collapsed: '0%'
};
openDrawer = () => setWidth(drawerWidth.expanded);
closeDrawer = () => setWidth(drawerWidth.collapsed);
function setWidth(width) {
document.getElementById(drawerName).style.width = width;
}

body {
font-family: 'Lato', sans-serif;
}
.overlay {
height: 100%;
width: 0;
position: fixed;
z-index: 1;
top: 0;
left: 0;
background-color: rgb(5, 3, 119);
background-color: rgba(63, 48, 204, 0.9);
overflow-x: hidden;
transition: 0.5s;
}
.overlay-content {
position: relative;
top: 25%;
width: 100%;
text-align: center;
margin-top: 30px;
}
.overlay a {
padding: 8px;
text-decoration: none;
font-size: 36px;
color: #ebebeb;
display: block;
transition: 0.3s;
}
.overlay a:hover,
.overlay a:focus {
color: #f1f1f1;
}
.overlay .closebtn {
position: absolute;
top: 20px;
right: 45px;
font-size: 60px;
}
@media screen and (max-height: 450px) {
.overlay a {
font-size: 20px;
}
.overlay .closebtn {
font-size: 40px;
top: 15px;
right: 35px;
}
}

<div>
<div id="sideNav" class="overlay">
<a href="javascript:void(0)" class="closebtn" onclick="closeDrawer()">&times;</a>
<div class="overlay-content">
<a href="#">About</a>
<a href="#">Services</a>
<a href="#">Clients</a>
<a href="#">Contact</a>
</div>
</div>
<span style="font-size:30px;cursor:pointer" onclick="openDrawer()">&#9776; open</span>
</div>
