CSS Fixed sidebar in the right - css

Question

I'm trying to make a two column responsive layout using bootstrap.
In the left column I want to place my content with the width of 100%/2, and in the right, a fixed sidebar with the width of 100%/3.
this is the css I used to my sidebar but in the fiddle I attached the sidebar is in left side and I want it to be in right side.
#sidebar-wrapper {
z-index: 1000;
position: fixed;
left: 250px;
width: 0;
height: 100%;
margin-left: -250px;
overflow-y: auto;
background: #000;
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
transition: all 0.5s ease;
}

How can I modify this to correspond to my needs ?

Answer 1

I modified your CSS:
#wrapper {
padding-left: 0;
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
transition: all 0.5s ease;
}
#wrapper.toggled {
padding-right: 250px;
}
#sidebar-wrapper {
z-index: 1000;
position: fixed;
right: 250px;
width: 0;
height: 100%;
margin-right: -250px;
overflow-y: auto;
background: #000;
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
transition: all 0.5s ease;
}
#wrapper.toggled #sidebar-wrapper {
width: 250px;
}
#page-content-wrapper {
width: 100%;
position: absolute;
padding: 15px;
}
#wrapper.toggled #page-content-wrapper {
position: absolute;
margin-right: -250px;
}
/* Sidebar Styles */
.sidebar-nav {
position: absolute;
top: 0;
width: 250px;
margin: 0;
padding: 0;
list-style: none;
}
.sidebar-nav li {
text-indent: 20px;
line-height: 40px;
}
.sidebar-nav li a {
display: block;
text-decoration: none;
color: #999999;
}
.sidebar-nav li a:hover {
text-decoration: none;
color: #fff;
background: rgba(255,255,255,0.2);
}
.sidebar-nav li a:active,
.sidebar-nav li a:focus {
text-decoration: none;
}
.sidebar-nav > .sidebar-brand {
height: 65px;
font-size: 18px;
line-height: 60px;
}
.sidebar-nav > .sidebar-brand a {
color: #999999;
}
.sidebar-nav > .sidebar-brand a:hover {
color: #fff;
background: none;
}
#media(min-width:768px) {
#wrapper {
padding-right: 250px;
}
#wrapper.toggled {
padding-right: 0;
}
#sidebar-wrapper {
width: 250px;
}
#wrapper.toggled #sidebar-wrapper {
width: 0;
}
#page-content-wrapper {
padding: 20px;
position: relative;
}
#wrapper.toggled #page-content-wrapper {
position: relative;
margin-right: 0;
}
}
