Thanks Kava, I have made a child them as you suggest and have opened the content.php file as directed, but I don’t have much experience of editing php. I’ll paste the original here, would you be able to tell me what the edit should be?
<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<?php
if ( is_sticky() && is_home() ) :
echo twentyseventeen_get_svg( array( 'icon' => 'thumb-tack' ) );
endif;
?>
<header class="entry-header">
<?php
if ( 'post' === get_post_type() ) {
echo '<div class="entry-meta">';
if ( is_single() ) {
twentyseventeen_posted_on();
} else {
echo twentyseventeen_time_link();
twentyseventeen_edit_link();
}
echo '</div><!-- .entry-meta -->';
}
if ( is_single() ) {
the_title( '<h1 class="entry-title">', '</h1>' );
} elseif ( is_front_page() && is_home() ) {
the_title( '<h3 class="entry-title"><a href="' . esc_url( get_permalink() ) . '" rel="bookmark">', '</a></h3>' );
