First thing is that, u were using .main instead of main in ur css.
Second thing is that, u dont need flexbox for centering ur box,
margin:auto;
on container is enough
Check the snippet below
* {
padding: 0;
margin: 0;
box-sizing: border-box;
}
html,
body {
height: 100%;
}
body {
padding: 1rem;
font-family: "Exo", sans-serif;
}
.main-parent {
height: 100%;
display: flex;
}
main {
margin: auto;
}
.container {
height: 80vh;
width: 80%;
border: 8px solid #3f3f3f;
}
.container__left {
height: 100%;
width: 100%;
clip-path: polygon(0 0, 50% 0, 48% 100%, 0 100%);
background-color: #1c1f24;
}
<div class="main-parent">
<main class="container">
<div class="container__left">
<div>I'm Jonathan Doe</div>
<div>Lorem ipsum Lorem ipsum Lorem ipsum Lorem ipsum Lorem ipsum v Lorem ipsumv Lorem ipsumLorem ipsumLorem ipsum v v</div>
<ul>
<li>one bla bla bla</li>
<li>two bla bla bla</li>
<li>three bla bla bla</li>
</ul>
<div>
<button>first</button>
<button>second</button>
</div>
</div>
<div class="container__right">
</div>
</main>
</div>
