Try this

@media screen and (max-width: 568px) {
header {
    padding: 1em 0;
    position: fixed;
    .logo {
        width: 200px;
    }
    .main-nav {
        display: none;
     }
     #burger-icon {
        width: 27px;
        display: block;
     }
}
#section1 {
    height: 500px;
    text-align: center;
}
#section2 {
    .col-1 {
        width: 100%;
        text-align: center;
    }
    .col-2 {
        width: 100%;
        padding: 0;
        margin-left: 0;
        margin-top: 20px;
        display: block;
    }
}
