I am currently working on a slider panel that covers the full height when opened. However, I have encountered an issue where the height remains fixed and the full content is not displayed when setting the body overlay to hidden. More information can be found at
body{
background-color:#FFF;
height:100%;
width:100%;
margin:0;
color:#ccc;
font-size:3em;
line-height:100px;
text-align:center;
overflow:hidden;
}
.slidernav{
background:#000;
position:absolute;
width: 100%;
height:100%;
top: 0;
right:-100%;
z-index:9999999999999999999999;
overflow:hidden;
}
