Hi @Marko,
Yes, you can add 5th Featured Content in the same line. Add custom CSS as below in “Appearance => Theme Options => Custom CSS” box:
@media screen and (min-width: 981px) {
#featured-post.layout-four .post:nth-child(4n+1),
#featured-post.layout-three .post:nth-child(3n+1){
clear: none;
}
#featured-post.layout-four .post{
width: 18%;
}
}
