Problems with fixed elements - html

Question

I'm struggling with the frontend of my page,
When there is a need for content to scroll I am attempting to keep the sidebar, navbar and title bar in the same place whilst allowing the content to scroll.
I thought I had this working until I added a panel to my page which is now causing an overlap. I've deliberately made my textarea massive below to show this.
I can't directly post images yet so heres a link (Edit now I can):
As you can see I'm also struggling to get my panels content to stretch the width of the panel

#sidebar {

height: 100%;
border-right: 0.1px solid rgb(225, 225, 225);
margin-top: 60px;

width: 230px;
font-weight: bold;
padding-top:10px;
display: block;

#titlenavwrapper{
z-index:5;
}
