I have a position: fixed div in a layout, as a sidebar. I've been asked to have part of it's content stay fixed to the top of it (internally), and the rest to scroll if it overflows the bottom of the div.
I've had a look at this answer, however the solution presented there doesn't work with position: fixed or position: absolute containers, which is a pain.
I've made a JSFiddle demonstration of my problem here. The large amount of text should ideally scroll, instead of overflowing into the bottom of the page. The height of the header can vary with content, and may be animated.

</div>Without a fixed header, I can simply add overflow-y: scroll to div.sidebar and I can happily scroll all it's content if it overflows the bottom of the container. However, I'm running into issues with having a fixed, variable height header at the top of the sidebar, and having any content underneath that scroll if it's too long to fit into the container.
div.sidebar must stay position: fixed, and I would very much like to do this without any hacks, as well as make it as cross browser as possible. I've attempted various things, but none of them work, and I'm unsure as to what to try from here.
How can I make a div inside a position: fixed container scroll only in the Y direction when it's content overflows the containing div, with a fixed header of varying, indeterminate height? I'd very much like to stay away from JS, but if I have to use it I will.
It seems to work if you use
div#scrollable {
overflow-y: scroll;
height: 100%;
}
and add padding-bottom: 60px to div.sidebar.
For example: http://jsfiddle.net/AKL35/6/
However, I am unsure why it must be 60px.
Also, you missed the f from overflow-y: scroll;
Actually this is better way to do that. If height: 100% is used, the content goes off the border, but when it is 95% everything is in order:
div#scrollable {
overflow-y: scroll;
height: 95%;
}
What worked for me :
div#scrollable {
overflow-y: scroll;
max-height: 100vh;
}
Set the scrollable div to have a max-size and add overflow-y: scroll; to it's properties.
Edit: trying to get the jsfiddle to work, but it's not scrolling properly. This will take some time to figure out.
I changed scrollable div to be with absolute position, and everything works for me
div.sidebar {
overflow: hidden;
background-color: green;
padding: 5px;
position: fixed;
right: 20px;
width: 40%;
top: 30px;
padding: 20px;
bottom: 30%;
}
div#fixed {
background: #76a7dc;
color: #fff;
height: 30px;
}
div#scrollable {
overflow-y: scroll;
background: lightblue;
position: absolute;
top:55px;
left:20px;
right:20px;
bottom:10px;
}
