How to fix side bar and header using CSS for JS & jQuery Scroller

Question

I have this layout and I want to make the left sidebar, right sidebar and the header fixed.

This is my css :

    #container {
        padding-left: 200px;      /* LC fullwidth */
        padding-right: 190px;     /* RC fullwidth + CC padding */
    }

    #container .column {
        position: relative;
        float: left;
    }

    #center {
        padding: 10px 20px;       /* CC padding */
        width: 100%;
        overflow-x:hidden;
    }

    #left {
        width: 180px;             /* LC width */
        padding: 0 10px;          /* LC padding */
        right: 240px;             /* LC fullwidth + CC padding */
        margin-left: -100%;
    }

    #right {
        width: 130px;             /* RC width */
        padding: 0 10px;          /* RC padding */
        margin-right: -100%;
    }

    #footer {
        clear: both;
    }

& the code is here

After this step, I want to add nanScrollerJS to the right side bar.

I'm not familiar with CSS

Is this what you were trying to do?

Fiddle

I've erased almost all of your code and replaced it with new code.

#fixed

position: fixed;
top: 0;
left: 0;
width: 100%;

#center

margin-top: 32px; /* Header height */
padding: 10px 20px; /* CC padding */
box-sizing: border-box;
border-left: 200px solid black; /* LC width including padding */
border-right: 150px solid black; /* RC width including padding */

#left

width: 180px; /* LC width */
padding: 0 10px; /* LC padding */
float: left;

#right

width: 130px; /* RC width */
padding: 0 10px; /* RC padding */
float: right;

#footer

position: relative;
z-index: 1;
