Obscure CSS inside WP

[toplisek]

I try to remove or hide obscure CSS from a WP theme. As all CSS is inside min. CSS in another folder, how to eliminate browser request without broken WP theme. This CSS is empty and it is without function but WP forces themes/themeID/style.css?ver=2021-03-18

I have seen it is inside PHP files and removed it.

Are you using a child theme and are the files you have edited part of your theme files or are they WP php files? I ask because if the files are WP php files you should copy any edited files to your child theme directory so they would not be replaced with unedited versions at the next update.

It is functions.php. Due to forum limitations, it can not be added images if I understand.
wp_enqueue_style()

That file (functions.php) is part of your theme, so a WP update will not alter that. It is a good idea to keep a 'note to self' record of the change you made, so if you change or update your theme in the future you will know to check/edit that file again. ;)

That's not an obscure style. That's the theme's css with a versioning parameter added to the end.

Versioning is a workaround to make sure that the latest version of the style sheet is served to users who might have an old version cached in their browser.

Is it true that wp_enqueue_style() can be hidden but a new installation of the theme will not work if wp_enqueue_style() is missing?
