Body width changes on mobile devices. Footer width changes

Question

When resizing the browsers window. Or when I use the responsive view in the dev tools, after about 600px the body gets smaller. Here is an image of my problem: Somehow the problem only exists in the chrome browser, in the Safari Browser it works. I created a JS Fiddle to show you the problem: https://jsfiddle.net/fpq6nyco/2/

I am pretty sure that the error sits in these lines:

@media (max-width: 726px) {
    .toggle-button {
        display: inline;
    }

    .navbar-links {
        display: none;
        width: 100%;
        z-index: 10;
        background-color: var(--primary-color);
    }

    .navbar {
        flex-direction: column;
        align-items: flex-start;
    }

    .navbar-links ul {
        width: 100%;
        flex-direction: column;
    }

    .navbar-links.active {
        display: flex;
    }

    .logo {
        display: inline;
    }

    .navbar-controls {
        display: flex;
        flex-direction: row;
        align-items: center;
        justify-content: space-between;
        height: 100%;
    }

    .container{
        display: flex;
        flex-direction: column;
        justify-content: space-around;
        align-items: center;
        width: 100%;
    }

    .item{
        width: 100%;
    }

    .info-section{
        margin-top: 200px;
    }

    .community-cont{
        display: flex;
        flex-direction: column;
        align-items: center;
        justify-content: space-around;
        margin-top: 50px;
        margin-bottom: 50px;
    }

    footer {
        width: 100%;
        height: auto;
        background-color: var(--dark-color);
        display: flex;
        flex-direction: column;
        align-items: center;
        justify-content: space-around;
        padding-top: 20px;
        padding-bottom: 20px;
    }

    .item-container {
        display: flex;
        flex-direction: column;
        align-items: center;
        justify-content: space-around;
        height: 40vh;
    }

    .text-cont-footer {
        color: var(--primary-color);
        width: 100%;
    }

    .footer-item {
        display: flex;
        flex-direction: column;
        justify-content: space-around;
        color: var(--primary-color);
        font-family: var(--primary-font);
    }

    
}

First the footer doesn't work on the width 1000px too, I changed that by removing the margin.
