Smaller size for general terms

Hello team, I saw a post about it but nobody answered, I am using the following:

#invoice-terms {
font-weight: normal;
font-style: italic;
font-size: 35%;
color: # CCC;

Yet I noticed no changes on the pdf invoices, any clue? I am looking to make the terms font smaller.

It depend which template you are using.

For example, the InvoicePlane template is found here :

    <?php if ($invoice->invoice_terms) : ?>
        <div class="notes">
            <b><?php _trans('terms'); ?></b><br/>
            <?php echo nl2br(htmlsc($invoice->invoice_terms)); ?>
    <?php endif; ?>

It is therefore not using the invoice_terms_id. In fact, none of the PDF templates seem to be.

If you want, add the style to the notes div as above as
<div id="invoice_terms" class="notes">
