Overlapping image with footer - CSS - html

Question

I have a design here that is part of a website footer.
https://ibb.co/mBRpx7Y
The website has a box kind of layout with a dark background. But in the footer, at the bottom right corner, there is an extra image pattern comes which will overlap the content section and also covert the background part.
Right now, I used CSS to achieve this by adding two background images. The image position is correct but the image pattern does not appear on the white container because it is not transparent. Is there any way to achieve this?
Here is the sample code of what I have right now:
body{
background-image: url(https://www.nicepng.com/png/full/10-102760_dot-background-png.png),url(https://images.unsplash.com/photo-1508615070457-7baeba4003ab?ixlib=rb-1.2.1&ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&auto=format&fit=crop&w=1470&q=80) !important;
background-size: auto, cover!important;
background-position: right bottom, left top!important;
background-repeat: no-repeat!important;
background-attachment: scroll, scroll;
}
.container{
max-width: 1500px;
margin:0px auto;
}
.section1{
min-height:200px;
background: #b0f3ff;
padding:50px;
}
.section2{
min-height:150px;
background: #fff;
padding:50px;
}
<div class="container">
<div class="section1">

Answer 1

You can use pseudo element on body e.g.: body:after {}. Make it absolute to bottom right corner and add this dotted background to it instead of on body.
body {
background-image: url(https://images.unsplash.com/photo-1508615070457-7baeba4003ab?ixlib=rb-1.2.1&ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&auto=format&fit=crop&w=1470&q=80);
background-size: cover;
background-position: left top;
background-repeat: no-repeat;
background-attachment: scroll;
position: relative;
margin: 0;
}
body:after {
content: '';
background-image: url(https://www.nicepng.com/png/full/10-102760_dot-background-png.png);
width: 380px;
height: 384px;
position: absolute;
bottom: 0;
right: 0;
}
.container {
max-width: 1500px;
margin: 0px auto;
}
.section1 {
min-height: 200px;
background: #b0f3ff;
padding: 50px;
}
.section2 {
min-height: 150px;
background: #fff;
padding: 50px;
}
<div class="container">
<div class="section1">
