Position modal centered with floating outside box - html

Question

I have a bootstrap 4 modal that I wish to display a little different. I want to display a floating box off to the left of the modal.
My question is how can I position both the modal and the floated box in the center of the page, even though the floating box is sitting outside the modal with a position absolute?
This is what it looks like currently, the floated box has a position absolute with a negative left position:
This is how I want it to look like, with the box and modal centered:
I don't know how much I have to modify the modal to do this, as I am hoping to make it responsive as well.
Would anyone have any ideas on how I could achieve this? It would be much appreciated.
Thanks, guys.

Add width: 91%; and left: 9%; to modal-content
.affix-box {
position: absolute;
top: -40px;
left: -100px;
width: 200px;
height: 100px;
background-color: green;
}
.modal-content{
width: 91%;
left: 9%;
}

Answer 2

Here is the simple replacement.
instead of top and left i have used transform: translate(-50%, -50%); which sets the center of the floating box on the top left corner of modal.
.affix-box {
position: absolute;
width: 200px;
height: 100px;
background-color: green;
-webkit-transform: translate(-50%, -50%);
-moz-transform: translate(-50%, -50%);
-ms-transform: translate(-50%, -50%);
-o-transform: translate(-50%, -50%);
transform: translate(-50%, -50%);
}

Answer 3

In addition to what #Joykal has said, you can also try changing the model size to reduce its width, you can use .modal-sm or .modal-lg class instead of .modal-xl depending on your need
<div class="modal-dialog modal-dialog-centered modal-xl" role="document">
