Post excerpts

What is the theme download link?

https://html5blank.com/

See: https://github.com/toddmotto/html5blank/blob/master/loop.php

Line 26: <?php html5wp_excerpt('html5wp_index'); // Build your custom callback length in functions.php ?>

change to:
<?php the_content(); ?>

Worked like a charm – thanks so much!

I’m not confident enough about PHP to have worked that out for myself.

function html5wp_excerpt() is used to display post excerpt. So replace it width the_content(), or access functions.php line:234 to modify html5wp_excerpt().

Got it! Thanks so much.
