Hi there. ??
There isn’t a built in way to change the H1 tags to H2 tags, however, you could achieve what you’re after if you feel comfortable creating a child theme and adding come custom code.
If you’re unsure what a child theme is, these guides give a good introduction and steps to get set up:
After you’ve created your child theme, paste the following to the bottom of your child theme’s functions.php file:
function isola_child_widgets_init() {
register_sidebar( array(
'name' => __( 'Sidebar', 'isola' ),
'id' => 'sidebar-1',
'description' => '',
'before_widget' => '<aside id="%1$s" class="widget %2$s">',
'after_widget' => '</aside>',
'before_title' => '<h2 class="widget-title">',
'after_title' => '</h2>',
) );
}
add_action( 'widgets_init', 'isola_child_widgets_init', 11 );
Save your changes and the titles in your widgets will then have H2 tags wrapped around them.
As an extra note: The use of multiple H1 tags in Isola is unlikely to impact your site’s SEO and is not necessarily considered bad practice. See here for some more discussion:
You’re, of course, free to change the code as you wish though. Let me know if any questions come up!
