wer gerne mit numerierten Überschritften arbeitet, für den Könnte dieser Code-Teil hilfreich sein:

<style>
    body {
        counter-reset: h1counter;
    }
    body.page-content.mce-content-body {
        counter-reset: h2counter;
        counter-increment: h1counter;
    }
    .page-content h1:not(.break-text):before {
        content: counter(h1counter) ".\0000a0\0000a0";
        counter-increment: h1counter;
    }
    .page-content h1 {
        counter-reset: h2counter;
    }
    
    .page-content h2:before {
        content: counter(h2counter) ".\0000a0\0000a0";
        counter-increment: h2counter;
    }
    .page-content h2 {
        counter-reset: h3counter;
    }
    
    .page-content h3:before {
        content: counter(h2counter) "." counter(h3counter) ".\0000a0\0000a0";
        counter-increment: h3counter;
    }
    .page-content h3{
            counter-reset: h4counter;
    }

    .page-content h4:before {
        content: counter(h2counter) "." counter(h3counter) "." counter(h4counter) ".\0000a0\0000a0";
        counter-increment: h4counter;
    }
    .page-content h4 {
        counter-reset: h5counter;
    }

    .page-content h5:before {
        content: counter(h2counter) "." counter(h3counter) "." counter(h4counter) "." counter(h5counter) ".\0000a0\0000a0";
        counter-increment: h5counter;
