How to make font awesome icon appear at centre inside a div - html

Question

I Googled for the above mentioned problem, but I still require the help from the stack overflow community.
In my login form, I am using font awesome icon. I have 2 input boxes for username and password respectively.
I want to display fa-user-cirle icon on top of the username input. The login form is displayed in a div as follows:
<div class="loginDiv">
<form>
<i class="fa fa-user-circle"></i>
<div class="container">
<input type="text" placeholder="Username" name="uname" required>
<input type="password" placeholder="Password" name="psw" required>
<button mat-button (click)="submit()">Login</button>
<label>
<input type="checkbox" checked="checked" name="remember"> Remember me
</label>
</div>
</form>
</div>
The CSS for icon is:
#import '~#angular/material/theming';
#include mat-core();
$yaana-app-primary: mat-palette($mat-orange, 800,400,200);
.firstDiv {
height: 40%;
width: 100%;
top: 0;
left: 0;
right: 0;
position: absolute;
background-color: orangered;
display: inline-block;
}
.secondDiv {
position: absolute;
width: 100%;
bottom: 0;
height: 60%;
left: 0;
right: 0;
background-color:whitesmoke;
display: inline-block;
}
.loginDiv {
border: 1px solid black;
background: white;
left: 50%;
position: absolute;
top: 28%;
transform: translate(-50%);
background-color: #fff;
padding: 15px;
box-shadow:1px 3px 10px rgba(0, 0, 0, 0.34);
}
input[type=text], input[type=password] {
width: 100%;
padding: 12px 20px;
margin: 8px 0;
display: inline-block;
border: 1px solid #ccc;
box-sizing: border-box;
}
button {
width: 215px;
height: 36px;
line-height: 36px;
background: transparent;
border-radius: 3px;
will-change: transform;
-webkit-transition: all .2s ease;
transition: all .2s ease;
border: none;
/*border: 2px solid #FF5126;*/
cursor: pointer;
background: #F26722;
font-size: 16px;
color: #fff;
outline: none;
text-align: center;
padding: 0 6px;
margin: 6px 8px;
font-size: 14px;
box-shadow: 0 2px 5px 0 rgba(0, 0, 0, 0.26);
text-transform: uppercase !important;
}
button:hover {
opacity: 0.8;
}
.loginImgContainer {
display: table;
max-height: 40px;
max-width: 40px;
}
i.fa {
background: #fff;
display: inline-block;
transform: scale(4,4);
border-radius: 50%;
}
The output I am getting is as follows:
But I want the icon to appear just above the username input and at the centre.
Please help me.

Answer 2

Try with adding row above the container,
<div class="loginDiv">
<form>
<div class="row center">
<i class="fa fa-user-circle"></i>
</div>
<div class="container">
<input type="text" placeholder="Username" name="uname" required>
<input type="password" placeholder="Password" name="psw" required>
<button mat-button (click)="submit()">Login</button>
<label>
<input type="checkbox" checked="checked" name="remember"> Remember me
</label>
</div>
</form>
</div>

Thanks for giving me hint and found out the solution with following changes in css,
i.fa {
background: #fff;
display: inline-block;
font-size: 80px;
transform: translateY(-60%);
transform: translateX(160%);
border-radius: 50%;
}
