I am working on a WordPress website built on custom theme in which I want to ignore some specific CSS codes coming from wordpress plugin style sheet.
To overwriting the plugin CSS you can use !important; for particular class
@media screen and (max-width: 575.98px) .gv-table-view tr:first-of-type {
border-top: 10px solid #000000!important;
}
If their available id it that div you can use id rather than !important; and it will work if The developer of the plugin was not using !important throughout the plugin CSS
