Fixed position relative to parent element [duplicate] - css

Fixed position but relative to container
(31 answers)
Closed 4 years ago.
I am relatively new to CSS. I have run into a problem where I am trying to fix an element next to its parent element. I am able to do so with the following code:
Parent element:
#search_results{
position:relative;
}
Child element:
.total {
position: fixed;
top:10px;
width:250px;
left: 75%;
/*overflow: hidden;*/
margin-left: -125px;
}
This works fine until the browser window is resized. When that occurs, the fixed element overlaps its parent element. You can see my problem here:

I am trying to fix the child element to the top of the page and the right-hand side of the parent element. Any ideas?

Edit:
You can use position: sticky; which can be relative to the parent element.
body > div {
height: 300px;
background-color: #ddd;
overflow: auto;
margin-top: 70px;
}
div > div {
height: 1000px;
position: relative;
}
span {
display: block;
height: 20px;
background-color: tomato;
position: sticky;
top: 0;
}
<div>
<div>
<span>This is a relatively sticky header</span>

Old Answer:
As per CSS Spec, the element positioned fixed is fixed to the viewport and not the containing element.
So the short answer is NO, you cannot have a fixed position element relative to it's parent element. You can use position: absolute; instead and tweak the top left right bottom parameters on the run using jQuery/JS.

Answer 2

Of course you can, just need an extra div!
<div class="fixed-wrapper">
<div class="close-wrapper">
<div class="close"></div>
</div>
</div>
body
background: gray
height: 8000px
.fixed-wrapper
position: fixed
top: 20px
left: 0
right: 0
.close-wrapper
max-width: 1200px
position: relative
.close
background: #fff
width: 30px
height: 30px
position: absolute
right: 0
border: 1px solid #515151
&:before,&:after
width: 25px
height: 1px
background: #515151
content: ''
position: absolute
top: 50%
left: 50%
display: block
#include transform(translate(-50%, -50%) rotate(45deg))
&:after
transform: translate(-50%, -50%) rotate(-45deg)

Answer 3

The best way to achieve this is to give parent element a transform css.
eg:
.relative{
transform: translateX(0); // this will act like relative parent
}
.fixed{
position: fixed;
left:0;
top:0;
width:100%; // width will be relative to the width of .relative
}

Answer 4

What you want to use is position:absolute . This places the child element according to it's parent element.
