Hey Again,

Add this into the Custom CSS box located in your Salient Options panel (Make Sure there are no red cross in the Box) :

@media only screen and (min-width: 1000px) {
    .container, body[data-header-format="left-header"] .container, .woocommerce-tabs .full-width-content .tab-container, .nectar-recent-posts-slider .flickity-page-dots, .post-area.standard-minimal.full-width-content article.post .inner-wrap, .material #search-outer #search {
        max-width: 900px;
    }
}

Thanks
