Hi There,
Please find this custom CSS:
.single-post .entry-featured, .entry-featured, .page .entry-featured {
display: none;
}
And change to this:
.single-post .entry-featured,
.page .entry-featured {
display: none;
}
That’s the default style of Ethos stack: http://demo.theme.co/ethos-1/. To make the filter texts BOLD, please add this custom CSS:
ul.x-portfolio-filters-menu.unstyled a {
font-weight: bold;
}
Please take a look at this ticket: https://theme.co/apex/forum/t/stop-images-losing-quality-as-featured-image/2059/6?u=thai.
Hope it helps
