wrong coding?

Within the Neve theme there is an ability to add “Additional CSS” coding. I have added (or the various plugins have added) coding here, but some isn’t working and my guess is there is an error somewhere in the coding. Now, I’m not familiar much at all with coding rules and was wondering if someone could look at the coding below to see if you can see any errors? Thanks in advance:

/* Link colors / .link-white a { color: #ffffff; text-decoration: none !important; } .link-black a { text-decoration: none !important; } / Responsiveness */
@media screen and (max-width: 600px) {
.contact-form {
width: 100%;
}
}
.archive.post-type-archive .shop-container .products.columns-4 {
display: none !important;
}
.archive.post-type-archive .nv-woo-filters {
display: none !important;
}
body {
-webkit-animation-duration: 0.1s;
-webkit-animation-name: fontfix;
-webkit-animation-iteration-count: 1;
-webkit-animation-timing-function: linear;
-webkit-animation-delay: 0.1s;
}

@-webkit-keyframes fontfix {
from { opacity: 1; }
to { opacity: 1; }
}
@media only screen and (max-width: 768px) {
.woocommerce #content div.product div.images, .woocommerce #content div.product div.summary, .woocommerce div.product div.images, .woocommerce div.product div.summary, .woocommerce-page #content div.product div.images, .woocommerce-page #content div.product div.summary, .woocommerce-page div.product div.images, .woocommerce-page div.product div.summary {
width: 100%
}
}
