<b>Why a "child theme" saves your custom work</b>

A theme controls how your site looks. A child theme is a small companion that sits on top of your main theme and holds your personal tweaks.

Why it matters: when you edit your theme's files directly and then update the theme, the update overwrites your changes. They vanish. A child theme keeps your edits in a separate, safe folder, so updates can't erase them.

How to get one:
— Many themes offer an official child theme to download from their site.
— Or use a free plugin like "Child Theme Configurator" to make one in a couple of clicks.
— Activate the child theme, and put any custom code there instead of the parent.

Think of the parent as a rented apartment and the child theme as your own removable decorations.

<i>In plain words:</i> a child theme protects your custom changes so theme updates can't wipe them out.
