Converting animated button style from css to styled-componenet - html

Question

While browsing net looking for a button style to apply to my register form's button, i found this nice animated button code, but it's in a simple HTML & CSS. i tried to convert theses to styled-component but i can't manage to make it 100% the same as it looks in codepen. Can you correct my code to make it similar to the original ones?
HTML :
<div class="wrapper">
<span>Hover Me!</span>
</div>
CSS :
.wrapper{
position: fixed;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
a{
display: block;
width: 200px;
height: 40px;
line-height: 40px;
font-size: 18px;
font-family: sans-serif;
text-decoration: none;
color: #333;
border: 2px solid #333;
letter-spacing: 2px;
text-align: center;
position: relative;
transition: all .35s;
}
a span{
position: relative;
z-index: 2;
}
a:after{
position: absolute;
content: "";
top: 0;
left: 0;
width: 0;
height: 100%;
background: #ff003b;
transition: all .35s;
}
a:hover{
color: #fff;
}
a:hover:after{
width: 100%;
}
My try JSX :
const Button = styled.button`
display: block;
width: 200px;
height: 40px;
line-height: 40px;
font-size: 18px;
font-family: sans-serif;
text-decoration: none;
color: #333;
border: 2px solid teal;
letter-spacing: 2px;
text-align: center;
position: relative;
transition: all 0.35s;
`;
const Span = styled.span`
&:after {
position: absolute;
content: "CREATE";
top: 0;
left: 0;
width: 0;
height: 100%;
background: teal;
transition: all 0.35s;
cursor: pointer;
}
&:hover {
color: white;
}
&:hover:after {
width: 100%;
}
`;
const Register = () => {
return (
<div>
<Button>
<Span>CREATE</Span>
</Button>
</div>
);
};
export default Register;

Answer 1

you put the &:after, &:hover and &:hover:after on the span and not on the button element.
try:
const Button = styled.button`
display: block;
width: 200px;
height: 40px;
line-height: 40px;
font-size: 18px;
font-family: sans-serif;
text-decoration: none;
color: #333;
border: 2px solid teal;
letter-spacing: 2px;
text-align: center;
position: relative;
transition: all 0.35s;
&:after {
position: absolute;
content: "CREATE";
top: 0;
left: 0;
width: 0;
height: 100%;
background: teal;
transition: all 0.35s;
cursor: pointer;
}
&:hover {
color: white;
}
&:hover:after {
width: 100%;
}
`;
const Span = styled.span`
position: relative;
z-index: 2;
`;
