Where can i make an html change to a specific page [closed]

It depends on your theme. To find out exactly which file to edit, add the following code to your header.php file inside /wp-content/themes/nameofyourtheme:

<!-- <?php global $template; print_r($template); ?> -->

You can then view the page in question’s source and see a comment that tells you the name of the file, which will also be somewhere inside your theme’s folder structure.

Once you open that file, it is possible that it’s calling another file – WordPress themes sometimes use template parts – if this is the case, the PHP code in the area you’re troubleshooting will have a call to get_template_part and you’ll need to find that separate PHP file. It sounds like this may not be the case though since it differs from page to page.
