By default, the WordPress system displays the full content of posts on the homepage and archive pages, which can be inconvenient for blogs with longer articles. To display post summaries instead of full content on these pages, you can modify the code in the file template-parts/content.php in the theme editor.
On line 25:
<?php
the_content(
sprintf(
// translators: %s: Post title.
__( 'Continue reading<span class="screen-reader-text"> "%s"</span>', 'twentysixteen' ),
get_the_title()
)
);Comment this out and change it to:
if(!is_single()) {
the_excerpt();
} else {
the_content(__('(more…)'));
}This will display the post summary on the homepage and archive pages, and the full content on single post pages.
