    The width is changing because the object when static is receiving its percentage width from its parent. Once you set the object to fixed it is no longer in flow and resizes.

    You're gonna have to set a size to your nav menu on its own and not expect the element to get its width from the parent.

    .nav {
        position: fixed;
        width: 20%;
        border: 1px solid green;
        padding: 0px;
        list-style-type:none;
        background:lightblue;
    }
