remove styling from child theme


Staff member
i am using wordpress and would like to delete a certain aspect of my parent theme's style, but also do not want to touch parent theme's styles.css. Thus i would like to remove that element from a child theme's style sheet, but how would i do that?

right now my child theme calls on my parent theme styles through

@import url("../parenttheme/style.css");

now i want to remove the whole section of

@media only screen and (max-width: 767px) { 
.container { max-width: 95% }
.sidebar-container { padding: 0; margin-top: 50px; }
.masthead-right { display: none }
.single-nav { position: inherit; top: auto; right: auto; margin: 20px 0 0; }
.single-nav-left, .single-nav-right { margin-left: 0; margin-right: 3px; }
.comment-list .children { margin-left: 0 }
#copyright, #footer-menu { text-align: center }
#footer-menu ul { float: none; margin-top: 5px; }
#footer-menu li { float: none; display: inliene; display: inline-block; margin-left: 0; margin-right: 10px; }
.related-posts .span_6, .related-posts .span_18, .related-posts .span_8 { width: 100%; padding: 0; }
.related-posts .span_8, .related-posts .span_6 { margin-bottom: 1.5em }
.tax-archives-filter { position: inherit; position: relative; top: auto; right: auto; margin: 30px 0 0; }
.tax-archives-filter > li { width: 100%; box-sizing: border-box; -moz-box-sizing: border-box; -webkit-box-sizing: border-box; }
.tax-archives-filter i { position: absolute; top: 50%; margin-top: -5px; right: 13px; }

in my parent theme styles by calling on it and nulling it from child theme.
