Though I may not see eye to eye with your approach to learning, you have the potential to create a stylish dual-pane effect using CSS. Just keep in mind that without JavaScript knowledge, you won't be able to trigger any click events - so it might be worth expanding your skillset in that area. Give it a try!
HTML:
<div class="container">
<div class="col left"></div>
<div class="col right"></div>
</div>
CSS:
html,body{
margin:0;
height:100%;
overflow:hidden;
}
.container{
height:100%;
width:100%;
background:#F8F8F8;
position:relative;
}
.col{
height:100%;
width:60%;
min-width:40px;
position:absolute;
top:0;
transition: 1s ease;
}
.left{
background:#888;
left:-50%;
}
.right{
background:#222;
right:-50%;
}
.right:hover{
right:0;
}
.left:hover{
left:0;
}
