<div><span class=”selector”><span class=”simple-selector selector-matches”>.primary-desktop-light .sh-header:not(.sh-sticky-header-active)</span></span> {</div>
<div><span class=”webkit-css-property”>background-color</span>: <span class=”value”>rgba(255,255,255,0.0)!important</span>;</div>
<div><span class=”webkit-css-property”>border-bottom</span>: <span class=”value”>1px solid rgba( 255,255,255,0.10 )!important</span>;</div>
