javascript - 在 976px 宽度之后添加/删除 CSS 样式？

Question

/*Fade in effect & one pager*/
.fullpage-wrapper {
    width: 100%!important;
    transform: none!important;
}

.fp-section {
    width: 100%!important;
    position: absolute;
    left: 0;
    top: 0;
    visibility: hidden;
    opacity: 0;
    z-index: 0;
    transition: all .7s ease-in-out;
}

.fp-section.active {
    visibility: visible;
    opacity: 1;
    z-index: 1;
}
/* Remove transition when website is still loading */
body {display:none}
body[class*="fp-viewing-"] {display:block}

我想为移动用户删除宽度低于 976 像素的这些给定样式。我怎样才能在 javascript 或 jquery 中完成这个？也可以让 else 打开吗？

if ($(window).width() < 967) {
   *remove these styles but how?*
}
else {
   *keep them/or do nothing*
}

你可以只使用 css:

@media only screen and (min-width : 967px) {
    /*Your styles */
}
