When a parent element is positioned (using position: relative or position: absolute) and contains a child element with position: absolute, the child element will be positioned absolutely inside the parent.
A child element with position: sticky will behave in a similar manner, being positioned stickily within the parent.
However, a child element with position: fixed will not be fixed within the parent element.
Example:
.panel {
display: inline-block;
position: relative;
width: 240px;
height: 180px;
margin-right: 6px;
overflow-x: hidden;
overflow-y: auto;
}
header, footer {
display: block;
position: fixed;
left: 0;
width: 240px;
height: 24px;
background-color: rgb(255, 0, 0);
}
header {
top: 0;
}
footer {
bottom: 0;
}
.panel + .panel header,
.panel + .panel footer {
position: sticky;
}
header code {
padding-left: 6px;
font-weight: bold;
color: rgb(255, 255, 255);
}<div class="panel">
<header><code>position: fixed</code></header>
<p>Alice was beginning to get very tired of sitting by her sister on the bank, and of having nothing to do: once or twice she had peeped into the book her sister was reading, but it had no pictures or conversations in it, `and what is the use of a book,' thought Alice `without pictures or conversation?'</p>
<p>So she was considering in her own mind (as well as she could, for the hot day made her feel very sleepy and stupid), whether the pleasure of making a daisy-chain would be worth the trouble of getting up and picking the daisies, when suddenly a White Rabbit with pink eyes ran close by her.</p>
<p>There was nothing so very remarkable in that; nor did Alice think it so very much out of the way to hear the Rabbit say to itself, `Oh dear! Oh dear! I shall be late!' (when she thought it over afterwards, it occurred to her that she ought to have wondered at this, but at the time it all seemed quite natural); but when the Rabbit actually took a watch out of its waistcoat-pocket, and looked at it, and then hurried on, Alice started to her feet, for it flashed across her mind that she had never before seen a rabbit with either a waistcoat-pocket, or a watch to take out of it, and burning with curiosity, she ran across the field after it, and fortunately was just in time to see it pop down a large rabbit-hole under the hedge.</p>

</div>Is there a method in CSS besides JavaScript to handle this scenario?
Can CSS offer a solution for child elements with position: fixed to be fixed within their positioned parent element?
