Re: Document structure in aggregated content

Continuing the ongoing conversation with myself. . .

I think I've decided to normalize the headings in PHP using
HtmlHeadingNormalizer <https://github.com/vikpe/php-html-heading-normalizer>.
Normalizing it in JavaScript could result in weirdness if the document
outline algorithm is ever implemented. This does mean I have to put in a
sort of placeholder H2 in some instances, because of the particular
constraints I'm operating under, but I *think* something like this is the
best way forward. So for any Wordpress theme developers, that would be
something like the following.

function normalize_content( $content ) {

// Check if we're inside the main loop in a single post page.
if ( !( is_single() && in_the_loop() && is_main_query() ) ) {
return @HtmlHeadingNormalizer::demote($content, 1);
}

return $content;
}
add_filter( 'the_content', __NAMESPACE__ . '\normalize_content' );
