</nav>
            <!-- Sidebar -->
        <div id="sidebar">

<div class = "container">
    <div class = "jumbotron">
        <img src="../afbeeldingen/toolsforever.jpg" alt="ToolsForever" class="img-responsive">
    </div>
</body>
</html>


<?php session_start(); 
//als session leeg is dan doe je dit
if(empty($_SESSION['email']))
{
    header("location:../index.php");
}

    include 'footer.php';
?>

Here is my code of my css file

body { 
    padding-top: 65px; 
    padding-left: 135px;
}

.container{
    padding-top: 65px;
    padding-left: 135px;
}



#sidebar{
    position: fixed;
    left: 250px;
    width: 0;
    height: 100%;
    margin-left: -250px;
    color: blue;
}

.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: black;
}

Can you guys please help me ;)

thank you!

You could use this code, but since the element is fixed you must give it a constant width property and so the responsiveness would probably be destroyed. Although you could use media queries to set when this element is visible. Underneath you have a fiddle.

#sidebar{
    position: fixed;
    left: 250px;
    width: 200px;
    min-height: 100vh;
    background-color:red;
    margin-left: -250px;
    color: blue;
}

To eliminate the blank white space between navbar and top navbar remove top body padding

body { 
    padding-left: 135px;
}

Updated the fiddle too :)

I think you would actually need to set background: blue on the sidebar-nav class instead of the sidebar id

Have a look at the below snippet i think you want something like this !

body{
  margin:0px;
}
.left-side{
   position:fixed;
   top:0px;
   left:0px;
   width: 20%;
   height: 100vh;
   overflow:auto;
   background-color:red;
}

.right-side{
   position:relative;
   width: 80%;
   margin:0px;
   margin-left:20%;
   min-height: 100vh;
   background-color:blue;
}
<div class="left-side">
  <ul>
  <li>item 1</li>
  <li>item 1</li>
  <li>item 1</li>
  <li>item 1</li>
  <li>item 1</li>
  <li>item 1</li>
  <li>item 1</li><li>item 1</li>
  <li>item 1</li>
  </ul>
</div>

<div class="right-side">
  Content container
</div>

</div>
