WordPress Child Themes: Why & How

What a Child Theme Is (Update-Safe Customizing)

Two files and one activation:

1. Create the folder — wp-content/themes/yourtheme-child.
2. style.css — with the required header:

`

/*

Theme Name: Your Theme Child

Template: yourtheme

*/

`

The Template: line is what binds the child to its parent — it must be the parent's exact folder name.

1. functions.php — enqueue the parent stylesheet (the wp_enqueue_style pattern, not @import).
2. Activate — Appearance → Themes → activate the child theme.

From then on, every customisation lives in the child: parent updates overwrite the parent folder and leave your work untouched — which is the entire point. The custom-CSS alternative covers lighter needs.

The 2 Required Files

How this plays out with child theme: settings that look cosmetic usually decide page speed and uptime under real traffic. The defaults WebJi® ships are tuned for Indian network conditions, and support can review your setup on request.

Step-by-Step: Create and Activate

The working sequence, verified end to end:

1. Locate the parent's folder name — Appearance → Themes → theme details shows the slug (e.g. astra).
2. Create wp-content/themes/astra-child via File Manager or SFTP.
3. Add style.css with the header above (Template: astra).
4. Add functions.php enqueueing the parent style with wp_enqueue_style hooked to wp_enqueue_scripts, using get_stylesheet_directory_uri() for the child's own CSS.
5. Activate the child; verify the site renders identically to before.
6. Begin customising: template overrides are copies of parent files placed in the child folder with the same path.

Test on staging the first time — a typo in the Template line activates an orphan theme, which is a five-second fix you would rather discover off-production.

Enqueue Parent Styles Correctly

On style.css Template header, the honest summary is that defaults matter more than brand names — a well-set budget plan outranks a mis-tuned premium one. WebJi® documents its defaults openly and adjusts them per ticket when workloads need it.

Overriding Templates (Copy and Edit)

Overriding Templates (Copy and Edit). Do the change this heading names on one site first, then check it in a private browser window or in the mail client, depending on the topic. Change one setting at a time, and undo it if the result is wrong before you try the next.

No-Code Alternatives (Custom CSS, Plugins)

Two practical notes on functions.php: it interacts directly with caching and database response, and misconfiguration is the most common cause of 'hosting is slow' tickets. WebJi® support checks it as part of standard migrations.

Child Themes vs Block Themes (FSE Note)

Update plugins and themes on a copy or straight after a backup, one at a time if the site is a shop. A white screen after an update is usually one plugin: rename its folder via the file manager to disable it. Remove plugins you do not use — they are unpatched code.
