Child Theme question regarding Core theme Updates
Since my troubles applying the core theme patch/update I have decided to go the Child Theme route to eliminate any future update problems. Although I am not understanding what is probably a simple concept with Child Themes I'm hoping someone can help me understand.
Say I modify the header.php file in my child theme, AND the next core upgrade/patch also includes an updated/changed header.php file, won't my child theme header.php file negate the upgraded core header.php thereby negating a portion of the upgrade/patch?
What am I missing here?
