CSS - Responsive Design

Question

I am working on this wordpress style sheet.

Below code, When I resize the screen using the mouse it kicks in and show the responsiveness. But when I use the Chrome Dev tools and clicking each different device sizes it does not kick in. Also I have checked this via my mobile phone and its not showing the responsive design.

What I'm doing wrong here?

.specials{
    display: flex;
    //padding: 30px;
    text-align: center;

    @media screen and (max-width: 600px){
        flex-direction: column;
    }
    .content{
        width: 50%;
        padding: 30px;
        background-color: rgba($color: $primary, $alpha: 0.5);
        display: flex;
        flex-direction: column;
        justify-content: center;
        p{
            line-height: 30px;
        }

        @media screen and (max-width: 600px){
            width: 100%;
        }
    }

    .image{
        width: 50%;
        //padding: 30px;
        background-color: #000;
        img{
            max-width: 100%;
            height: auto;
        }

        @media screen and (max-width: 600px){
            width: 100%;
        }
    }
}

If your page is rendering things too small in the browser's responsive mode, then you probably forgot the viewport meta tag:

<meta name="viewport" content="width=device-width,initial-scale=1.0">

Adding that will render your site at the proper size for mobile devices (including those emulated by the reponsive mode in desktop browsers).
