    If the code returns prematurely, you will not get any CSS at all if an empty value is encountered. Each value that might be empty needs to be checked with something like if ( ! empty( $value ) ) : before the related CSS is concatenated into the overall CSS. In some, but not all cases, this is already done.

    Instead of not concatenating a CSS rule, it might be better to assign a default value when the respective $value is empty.

    Alternately, if you can come up with a regexp (or few) that would capture any CSS with an empty value, you could use preg_replace() to remove offending rules after the entire CSS is determined.

    Regexp isn’t my forté. You can test and develop an appropriate expression using your own test data at sites like regexr.com. Be sure to include similar test data that you don’t want to capture. Such as similar CSS rules that have values.

    ok lets get back to the first one so i need to add something like that ?

    	if ( ! empty( $atp_h1 ) ) {
	$custom_css .= anona_generate_font_prop( array( 'h1' ), $atp_h1 );
	}

    Yes, that’s what I’m suggesting.
