create a submit button with spinner - html

Question

I want the spinner to be placed here as a part of the submit input button:
But I'm unable to find a proper solution, here is what I tried:
/*button itself*/
.btn {
font-family: "iransansdnlight";
max-width: 200px;
width: 100%;
background-color: #ad69f4;
border: none;
outline: none;
height: 40px;
border-radius: 49px;
color: #fff;
text-transform: uppercase;
font-weight: 600;
margin: 5px 0;
margin-top: 15px;
cursor: pointer;
transition: 0.5s;
opacity: 1;
}
.btn:not(.disabled):hover {
background-color: #9f5ae7;
}
/*Submit Spinner*/
.submit-container {
display: flex;
flex-direction: row;
max-width: 200px;
width: 100%;
}
.spinner {
font-size: 20px;
position: relative;
display: inline-block;
width: 1em;
height: 1em;
}
.spinner.center {

Answer 1

You need to use position:absolute instead of relative.
You can position it 50% from top. And since the width/height of the spinner is known, you can use a negative top margin to give some offset based on the center of the spinner.
/*button itself*/
.btn {
font-family: "iransansdnlight";
max-width: 200px;

outline: none;
height: 40px;
border-radius: 49px;
color: #fff;
text-transform: uppercase;
font-weight: 600;
margin: 5px 0;

Answer 2

You have used absolute positioning, so you only need to tweak the left and top attributes of the .spinner.center. I also took the liberty to change the color of your blades, so they are in contrast with the background.
/*button itself*/
.btn {
font-family: "iransansdnlight";
max-width: 200px;
width: 100%;
background-color: #ad69f4;
border: none;
outline: none;
height: 40px;
border-radius: 49px;
color: #fff;
text-transform: uppercase;
font-weight: 600;
margin: 5px 0;
margin-top: 15px;
cursor: pointer;
transition: 0.5s;
opacity: 1;
}
.btn:not(.disabled):hover {
background-color: #9f5ae7;
}
