How to remove type attribute type="text/css" for the style element

Hi Ben,

You can try this PHP code:

add_action( 'after_setup_theme', function() {
add_theme_support( 'html5', [ 'script', 'style' ] );
});

This PHP code will remove all the type attributes from <script> and <style> tags on the entire page.

Here's how to add PHP - https://docs.generatepress.com/article/adding-php/

That's already in there and works on everything EXCEPT simple css plugin.

I can see in the actual plugin it has the line 231
// Finally, print it
echo '<style type="text/css" id="simple-css-output">';
echo strip_tags( $output );
echo '</style>';

Any way to override or filter this?

Oh, alright.

You can try this out. Reference: https://stackoverflow.com/a/50853611

add_action('wp_loaded', 'prefix_output_buffer_start');
function prefix_output_buffer_start() { 
    ob_start("prefix_output_callback"); 
}

add_action('shutdown', 'prefix_output_buffer_end');
function prefix_output_buffer_end() { 
    ob_end_flush(); 
}

function prefix_output_callback($buffer) {
    return preg_replace( "%[ ]type=[\'\"]text\/(javascript|css)[\'\"]%", '', $buffer );
}

This one does scans through things after load.
