@media screen and (min-width: 360px) and (max-width: 375px){
    .ejiao_description .form form p{
        margin-bottom: 11px;
    }
}

The media query in css is written like this
js

var screen1 = window.matchMedia('@media  (min-width: 360px) and (max-width: 375px)');
    if (screen1.matches){
        XXXXXX.....
    }
    else{
        XXXX....
    }

But it doesn’t work now. What’s wrong?
