fixed position div inside div container

Screenshot:

This is how position: fixed; behaves:

MDN link

Do not leave space for the element. Instead, position it at a specified position relative to the screen's viewport and doesn't move when scrolled. When printing, position it at that fixed position on every page.

Hence, to get what you want you have to use something more than fixed positioning:

Probably this:

.wrapper { width: 100% } .container { width: 300px; margin: 0 auto; height: 500px; background: #ccc; } .element { background: #f2f2f2; position: fixed; width: 50px; height: 70px; margin-left: 250px; border: 0px solid #d6d6d6; }

<div class="wrapper"> <div class="container"> <div class="element"> fixed </div> </div> </div>

Make the element's parent container have position: relative

Instead of using top or left use margin-top and/or margin-left

If you only use top that will position the element based on the window, but if you use margin-top that will position based on the parent element. Same goes for left or right

<div class="parent"> <div class="child"></div> </div> .parent { position: relative; } .child { position: fixed; margin-top: 30px; margin-left: 30px; } 

I found the answer to that :

 <div class="container"> <div class="inContainer"> <p> coucou </p> </div> <div> <p> other thing</p> </div> </div> 

You want that class="inContainer" are in class="Container" in fixed position but if you scroll with the navigator scroll you don't want that the class="inContainer" move outside the class="container"

So you can make something like that

.container{ height: 500px; width: 500px; overflow-y:scroll; } .inContainer { position: absolute; } 

So class=inContainer will be always on the top of you're class=Container and move with you're class=container if you scroll with navigator scroll =)

(tested only with chrome)

No it's impossible because fixed property throws the element out of the flow so it doesn't depend to anything on the document and yes it is no more contained in your container : )

Yes, you can do it, just use margin-top property instead of top property.

When you use position: fixed and specify a top and or left position, you'll find that the element will be fixed relative to the window, and not to any other element of position: relative.

There is a way around this and that is not to specify top and left positions but instead to use margin-left and margin-top on the position: fixed element.

The behavior of the positioning is mentioned in the AdityaSaxena's answer https://stackoverflow.com/a/18285591/5746301

For creating a fixed position cart, you can also do it with using the jquery.

If we apply the Left or right value or margin, we may face some issue while responsive.

In the below snippet, I have placed the fixed element at the right of the container.

Even if the width of the container increased the fixed element placed accordingly.

Here is the jsfiddle Demo URL

//Jquery $(document).ready(function(){ var containerWidth = $(".container").outerWidth(); var elementWidth = $(".element").outerWidth(); var containerOffsetLeft = $(".container").offset().left; var containerOffsetRight = containerOffsetLeft + containerWidth - elementWidth;	$(".element").css("left", containerOffsetRight); });

//CSS .wrapper { width:100% } .container { width:300px; margin:0 auto; height:900px; background:#ccc; } .element { background:#f2f2f2; position:fixed; width:50px; height:70px; top:50px; border:1px solid #d6d6d6; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="wrapper"> <div class="container"> <div class="element"> fixed </div> </div> </div>

Hope this may help you.

Thanks

If you are looking to show the cart even when the user scrolls that is fixed then you should use position:fixed for the cart (if .container is your cart), because it should be shown with respect to screen/viewport. Your current code will only show the element which is positioned absolutely inside the container. If you want it to be like that then give :

.container { position:relative; } .element { position:absolute; top:50px; right:0px; } 

<div style="position: fixed;bottom: 0;width: 100%;"> <div class="container" style="position: relative;"> <div style="position: absolute;right: 40px;bottom: 40px;background:#6cb975;border-radius: 50%;width: 40px;text-align: center;height: 50px;color: #fff;line-height: 50px;"> F </div> </div> </div> 

You can just add

.element { left:368px; }
