A problem when I set height/width of the body - html

Question

I'm trying to create a normal HTML page and I've set the height/width of the body With Vh and Vw
* {
padding: 0;
margin: 0;
}
body {
height: 100vh;
width: 100vw;
background-color: red;
padding: 0;
margin: 0;
overflow: auto;
}
.Top-banner {
position: absolute;
top: 0;
left: 0;
height: 10%;
width: 100%;
background-color: blue;
box-sizing: border-box;
}
.Ad {
position: absolute;
top: 10%;
left: 0;
height: 15%;
width: 100%;
background-color: purple;
text-align: center;
box-sizing: border-box;
}
.Ad .Close-but {
position: absolute;
top: 65%;
left: 5%;
height: 30%;
width: 10%;
background-color: green;
text-align: center;
}
.Main-content {
position: absolute;
top: 25%;
left: 0;
height: 100%;
width: 100%;
background-color: pink;
text-align: center;
box-sizing: border-box;
}
<div class="Top-banner">
</div>
<div class="Ad">

Not sure if understand your question correctly but if your problem is the horizontal scrollbar then simply change 'overflow: auto;' to 'overflow-x: hidden;'
if you don't want a vertical scroll aswell then make 'overflow: hidden;'
body{
height: 100vh;
width: 100vw;
background-color: red;
padding: 0;
margin: 0;
overflow-x: hidden; //change this
}
