how to custom profile pic input like facebook - html

Question

I would like to custom my profile pic like in this picture but I can't, don't know what's wrong.
I have an external bootstrap CSS file though. What I want to follow the Facebook profile pice update design but facing small issue, I have attached a pic to see how I want it
HTML
<div class="user-thumb user-thumb--edit">
<div class="custom-file">
<input class="custom-file__input" id="photo" accept="image/*" type="file">
<label class="custom-file__label" for="photo">
<img alt="" class="thumb--lg rounded-circle" src="">
</label>
</div>
</div>
Here is the CSS
.user-thumb {
position: relative;
display: inline-block;
background: #e9e9e9;
border-radius: 50%;
}
.user-thumb--edit {
position: relative;
margin-bottom: 1rem;
}
.custom-file {
margin: 0;
height: auto;
}
.custom-file__input {
position: absolute;
opacity: 0;
visibility: hidden;
width: 1px;
height: 1px;
}
.custom-file__label {
cursor: pointer;
border: 0;
text-align: center;
font-weight: 500;
font-size: 1rem;
display: block;
margin: 0;
border-radius: 0;
padding: 0;
background: transparent;
position: relative;
}
.user-thumb--edit .custom-file__label::before {
content: '';
position: absolute;
bottom: 0;
right: 0;
text-align: center;
transition: all 0.15s ease-in-out;
z-index: 20;
background: #ffffff url();
background: 1.4rem auto;
width: 4.2rem;
height: 4.2rem;
border-radius: 100%;
box-shadow: 0px 6px 6px -3px rgb(0 0 0 / 20%), 0px 10px 14px 1px rgb(0 0 0 / 14%), 0px 4px 18px 3px rgb(0 0 0 / 12%);
}

Answer 1

You can achieve this if you set the border-radius of the label to 50% instead of 0 and add overflow: hidden, which would also hide a part of the ::before. Therefor you should define that ::before not for the label but for the containing div: .custom-file::before.
Working example:
.user-thumb {
position: relative;
display: inline-block;
background: #e9e9e9;
border-radius: 50%;
}
.user-thumb--edit {
position: relative;
margin-bottom: 1rem;
}
.custom-file {
margin: 0;
height: auto;
}
.custom-file__input {
position: absolute;
opacity: 0;
visibility: hidden;
width: 1px;
height: 1px;
}
.custom-file__label {
cursor: pointer;
border: 0;
text-align: center;
font-weight: 500;
font-size: 1rem;
display: block;
margin: 0;
border-radius: 50%;
padding: 0;
background: transparent;
position: relative;
overflow: hidden;
}
.user-thumb--edit .custom-file::before {
content: '';
position: absolute;
bottom: 0;
right: 0;
text-align: center;
transition: all 0.15s ease-in-out;
z-index: 20;
background: #ffffff url();
background: 1.4rem auto;
width: 4.2rem;
height: 4.2rem;
border-radius: 100%;
box-shadow: 0px 6px 6px -3px rgb(0 0 0 / 20%), 0px 10px 14px 1px rgb(0 0 0 / 14%), 0px 4px 18px 3px rgb(0 0 0 / 12%);
}
<div class="user-thumb user-thumb--edit">
<div class="custom-file">
<input class="custom-file__input" id="photo" accept="image/*" type="file">
<label class="custom-file__label" for="photo">
<img alt="" class="thumb--lg rounded-circle" src="https://via.placeholder.com/150">
