Building Web Layouts with Flexbox and Grid question

I have reviewed my code with the professor and cannot figure out why I am getting 3 columns that don’t span the entire screen. I even copied the professor code and go the same thing. Can you please explain this to me?

* {
padding: 0;
margin: 0;
box-sizing: border-box;
}

html {
font-size: 10px;
}
header {
background-color: yellowgreen;
}
header::after{
content: "Menu";
position: absolute;
top: 1rem;  
right: 0;
margin-right: 3rem;
}
.header-navigation{
    display: none;
}

.section-banner {
background-color: blue;
}
.section-info {
    background-color: red;
}
.section-portfolio{
background-color: green;
}
.section-contact{
    background-color: yellow;
}
.section-footer{ 
    background-color: lightseagreen;
}
.container{
font-size: 1.6rem;
padding: 1rem 3rem;
margin: 0 auto;
border: 1px solid black;
}
.portfolio-list {
    list-style: none;
}
.portfolio-item {
    background-color: lightyellow;
    border: 1px solid black;
}

@media screen and (min-width: 576px) {
    header{ 
        display: flex;
    }
    header::after{
        content: none;
    }
    .header-logo{
        flex-grow: 2;
    }
    .header-navigation {
        display: inline-block;
        flex-grow: 3;
    }
.menu-list{ 
    list-style: none;
    display: flex;
justify-content: flex-end;
}
.menu-item{ 
border: 1px solid black;
background-color: deepskyblue;
margin: 0 1rem;
    }
}
@media screen and (min-width: 768px){
  .portfolio-list{
    /*display: grid;
    grid-template-columns: auto auto;*/
display: flex;
flex-wrap: wrap;
}
.portfolio-item{ 
    width: 50%;
    }
}
@media screen and (min-width: 992px){
    .container {
        width: 100%;
    }
    .portfolio-item {
        width: calc(100% / 3);
    }
    main {
    display: flex;
    flex-wrap: wrap;
    }   
    .section-banner,
    .section-info {
    width: 50%;
    }
    .section-portfolio,
    .section-contact {
    width: 100%;
    }

}

Thank you!
