I am using the twentyseventeen theme on my Wordpress installation. I've set an "About Me" as my static home page. I've created a "Blog" page which is set as the "Posts Page" using the "Customize" menus. The index.php of this theme (pastebin: http://pastebin.com/aap6j2A7) has been modified (lines 34-40) to filter out posts of a certain category (ID = 18) using
category__not_in => array(18)
"category__in" => array(18)
In twentyseventeen theme styles are added based on the body class function . for example
body.home h1 {
color :red;
}
this style works only in home page.
