CSS - scrollable sidebar including footer
I have a sidebar with a footer fixed on the bottom of the sidebar. I want to add a scrollable sidebar when it encounters short height.
My HTML:
<div>
<aside>
<header>
....
</header>
<ul>
<li> ... </li>
<li> ... </li>
</ul>
<footer>
<li> ... </li>
</footer>
</aside>
....
....
</div>
My CSS:
.aside {
background:yellow;
overflow-y:scroll;
min-height:100vh; // I also tried height: 100%;
}
.header {
overflow: hidden;
}
.ul {
...
}
.footer {
position:fixed;
bottom:0;
}
When I do height:100%, it seems like aside is ignore the existence of the footer. On the other hand, when I set min-height:100vh, my footer is fixed so it follows the browser's scrollbar for the entire div.
What I am trying to achieve is that if the user adjust the height of the browser, I want the sidebar to be responsive and appear a scrollable sidebar. I prefer just using only CSS & HTML to achieve this behavior.

Below there's an example how I usually go about creating a sidebar. (I think you're after something like the below). I've added a bit of style to the div wrapper you have around the aside just to have some "global" CSS for the sidebar itself.
I've also added some content to showcase how it will work. The footer is working as expected. One issue I encountered is that to set the width of the footer you cannot use percentages as since it has a position of fixed it is "relative" to the window and not to its parent element.
Of course the example would need a bit of refining but hopefully it will point you to the right solution.
html, body {
height: 100%;
}
#sidebar-wrapper {
position: fixed;
width: 250px;
height: 100%;
float: left;
}
aside {
background:yellow;
overflow-y:scroll;
height: 100%;
width: 100%;
position: relative;
}
header {
overflow: hidden;
}
ul {
}
footer {
position: fixed;
bottom: 0;
background-color: red;
}
main {
margin-left: 250px;
float: left;
}<div id="sidebar-wrapper">
<aside>

html, body {

}
#sidebar-wrapper {
position: fixed;
width: 250px;
height: 100%;
float: left;
}
aside {
background:yellow;
overflow-y:scroll;
height: 95%;
width: 100%;
}
header {
overflow: hidden;
}
ul {
}
footer {
background-color: red;
width: 100%;
}
main {
margin-left: 250px;
float: left;

The issue here is that when you say height 100% or 100vh it doesn't know the height of the footer and doesn't take it into account. Position fixed will remove it from the "flow" of the document and affix it to however you decide to position it using top, left, right, bottom, height and width.
If your footer is a fixed height, you could use calc(100% - fixedHeight)
If your footer is a variable height, I'd suggest looking into flexbox layouts to solve your problem: https://css-tricks.com/snippets/css/a-guide-to-flexbox/
