List-style-image not shown for li - html

Question

I am currently playing arround with customizing lists in HTML and CSS, so I tried to use custom images to be used for the li 'dot'.
However, it is not shown. Could someone tell me whats wrong with this code snippet?
body {
margin:0;
}
.container {
display:flex;
flex-wrap:wrap;
flex-direction:row;
height:100vh;
background-color: white;
}
.container > div {
min-height: 100vh;
border: 1px solid black;
box-sizing:border-box;
background-color: inherit;
}
container > div .content{
height: 100vh;
width: 100vw;
background-color: inherit;
}
.full-width {
width:100%;
}
.half-width {
width:50%;
}
.half-width > .half-width-content{
position: relative;
margin-top: 0;
height: 100%;
width: 100%;
}
list-div {
height: 100%;
display: flex;
justify-content: center;
align-items: center;
}
.list-div ul {
padding: 0;
width: 75%;
}
.list-div li {
position: relative;
margin-bottom: 5px;
padding: 10px;
text-align: left;
visibility: visible;
text-transform: uppercase;
}
.list-div li:nth-child(1){
list-style-image: url('https://fakeimg.pl/30x30/?text=A');
list-style-position: outside;
}
<div class="container">
<div class="half-width">
<div class="half-width-content">
<div class="list-div">
<ul class="items-list" id="list">
<li>List item A</li>
<li>List item B</li>
<li>List item C</li>
<li>List item D</li>
</ul>
</div>
</div>
</div>
</div>
</div>

Use list-style-type: none; and
margin-left:40px; to li
body {
margin:0;
}
.container {
display:flex;
flex-wrap:wrap;
flex-direction:row;
height:100vh;
background-color: white;
}
.container > div {
min-height: 100vh;
border: 1px solid black;
box-sizing:border-box;
background-color: inherit;
}
container > div .content{
height: 100vh;
width: 100vw;
background-color: inherit;
}
.full-width {
width:100%;
}
.half-width {
width:50%;
}
.half-width > .half-width-content{
position: relative;
margin-top: 0;
height: 100%;
width: 100%;
}
list-div {
height: 100%;
display: flex;
justify-content: center;
align-items: center;
}
.list-div ul {
padding: 0;
width: 75%;
}
.list-div li {
position: relative;
margin-bottom: 5px;
padding: 10px;
text-align: left;
visibility: visible;
text-transform: uppercase;
list-style-type: none;
margin-left:40px;
}
.list-div li:nth-child(1){
list-style-image: url('https://fakeimg.pl/30x30/?text=A');
list-style-position: outside;
}
<div class="container">
<div class="half-width">
<div class="half-width-content">
<div class="list-div">
<ul class="items-list" id="list">
<li>List item A</li>
<li>List item B</li>
<li>List item C</li>
<li>List item D</li>
</ul>
</div>
