I can't seem to get these two buttons line up buttons like this. How can I do this?

Design:

Explanation: So I used a div and added CSS (display: inline-block;) and width to it, they were perfectly fine, when I added a tag into it to actually make the buttons do something they went on top of each other, I have tried wrapping them tag in another div but can't seem to make it work.

Here is how they look right now:

HTML:

export default function About() {
    return (

        <div className="About--div">

            <h3 className="About--name">Huzaifa Aziz</h3>
            <h5 className="About--job">Frontend Developer</h5>
            <a className="About--site"></a>
            <div className="About--btn">
                <div>
                <form action="mailto:[email protected]">
                    <button className="Email--btn" ><i className='fa fa-envelope'></i> Email</button>
                </form>
                <div className="About--btn--space"></div>
                <form action="https://www.linkedin.com/in/huzaifah-aziz-63092996/">
                    <button className="Linkedin--btn"><i className='fa fa-linkedin'></i> Linkedin</button>
                </form>
                 </div>
                 </div>
        </div>
    )}

CSS:

* {
    box-sizing: border-box;
   
}
body{
    border-radius: 20px;
    background: #23252C;
    margin: auto;
    width: 100%;
    border: 3px solid #1A1B21;
    padding: 10px;
    font-family: 'Inter', sans-serif;
}

.About--div{
    text-align:center
    
    }

.About--name{
    color: white;
} 
   
.About--job{
    color: #F3BF99;

}

.About--site{
    color: #F5F5F5;

}
.About--btn{
    margin-top: 15px;
}
.About--btn--space{
    width: 17px;
    display: inline-block;
}

.Email--btn{
    background: whitesmoke;
    border: none;
    width: 115px;
    height: 34px;
    border-radius: 5px;
          
}

.Linkedin--btn{
    background: #5093E2;
    border: none;
    width: 115px;
    height: 34px;
    color: white;
    border-radius: 5px;
    
    
}

.fa fa-linkedin{
   
}
