Can't render input inline - html

Question

I'm trying to create an input with an icon indicating its purpose, but it's not rendering how I like:
I want the input at the same level as the icon, however, dispite my best efforts:
.field
{
margin: auto;
border-radius: 10px;
width: 67%;
white-space: nowrap;
overflow-x: auto;
}
.field input, .field label
{
display: inline-block !important;
margin: 0;
padding: 0;
}
<div class = 'field w3-bar w3-center w3-border w3-border-green'>
<label class='w3-bar-item w3-left w3-border-right w3-border-green fas fa-user' for='username'></label>
<input class="w3-bar-item w3-right w3-input w3-border-green w3-hover-border-green no-box" id="username" name="username" required type="text" value="">
</div>
— it still renders on a new line! Note that I'm using w3.css and font-awesome. Is there something I'm missing? Thank you.

How about like this?
.custom-input{
display:inline-block;
margin-left:12px;
}
.input-component{
border:3px solid teal;
padding:8px;
padding-left:30px;
}
.input-icon{
color:teal;
position:absolute;
margin-right:-30px;
}
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css">
<div class="custom-input">
<span class="glyphicon glyphicon-user input-icon"></span>
<input class="input-component" placeholder="username...">
</div>
<div class="custom-input">
<span class="glyphicon glyphicon-calendar input-icon"></span>
<input class="input-component" type="date">
</div>
<br>
<br>
<div class="custom-input">
<span class="glyphicon glyphicon-lock input-icon"></span>
<input class="input-component" type="password" placeholder="password"/>
</div>

You can minimize the code to something like this:
<div style="width: 67%;display:flex; align-items:center;" class ="w3-padding w3-margin w3-border w3-border-green w3-round-large">
<label style="width:10%" class="w3-center w3-border-right w3-border-green fa fa-user" for="username"></label>
<input style="width:80% " class="w3-input" id="username" name="username" required type="text" value="">
</div>
And you don't need define the class "field" and the others.
