Fixed position relative to parent container

**Windbrand** · 03-01-2013 09:10 PM

I did a lot of research on this but apparently it's not possible with pure html/css as position:fixed only fixes it to browser window, so I thought I'd ask in this section.
I have a page container, and inside it are two sections. The left section is a vertical nav bar with some links, while the right section is the actual page content. I want the right side to be scrollable, but the left side to be fixed to the page container (ie won't scroll when I scroll that page), but be able to move when I scroll the entire browser window.

Code:

<div id="pagecontainer">

    <div id="linkspage">

        <div class="sidelinks"> <!--UNSCROLLABLE-->
            <a href="#page1" class="link">Link 1</a>
            <p>
            <a href="#page2" class="link">Link 2</a>
            <p>
            <a href="#page3" class="link">Link 3</a>
            <p>
            <a href="#page4" class="link">Link 4</a>
            <p>
        </div>

        <div class="linkscontent"> <!--SCROLLABLE-->
            content of links page
        </div>

    </div>

    //OTHER PAGES

</div>

I've already tried to set #pagecontainer and #linkspage to position:relative, and .sidelinks to position:absolute, that doesn't do anything as far as I can tell... or it just doesn't do what I want.

Here's a picture:

Thanks.

Assuming you have used CSS to arrange both divs to be side by side in the parent container, you might try something like:

Code:

window.onload = function(){
   var side, content;
    side = document.getElementById('sidelinks');
    content = document.getElementById('linkscontent'); //to be scrolled
    content.style.display = "none";  //remove for measurement
    content.style.height = side.offsetHeight + 'px';
    content.style.overflow = "scroll";
    content.style.display = "block"; //make visible again
}

Maybe this will be an answer to your request.

I would like to remind you that this can be achieved without JavaScript and it is always better to do things with css first.

HTML Code:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>odd ball</title>
<style>
.page{background-color:lime;margin:1em;padding:1em;position:relative;max-width:52em;}.stuf1{position:relative;background-color:red;height:30em}.link1{position:absolute;width:10em;top:1px;left:1px;background-color:#CCC}.tent1{position:absolute;width:40em;height:30em;top:1px;left:11em;background-color:pink;overflow:scroll}.stuf2{position:relative;background-color:blue;height:30em}.link2{position:absolute;width:10em;top:1px;left:1px;background-color:#eee}.tent2{position:absolute;width:40em;height:30em;top:1px;left:11em;background-color:purple;overflow:scroll}.stuf3{position:relative;background-color:green;height:30em}.link3{position:absolute;width:10em;top:1px;left:1px;background-color:#999}.tent3{position:absolute;width:40em;height:30em;top:1px;left:11em;background-color:yellow;overflow:scroll}
