Here’s How You Can Create Your Own WordPress Child Theme

How Does A WordPress Child Theme Work?

A separate directory is created for each child theme and each such directory includes its own style.css as well as functions.php files. You can add more customized files but these 2 are more important for functioning. These files help you to modify the style, layout, coding, scripts, etc in your child theme even if they are absent in the parent directory.

  • Create a New Folder with your child theme’s name
  • In this folder, create a New File with style.css as its name.
  • Include the necessary code for your child theme
  • Name this theme. Modify other values according to your domain name and theme. The Template field includes the parent theme and hence is very important. Finally, click on Save.
  • In the same folder now create a functions.php file with a separate code than the parent theme’s one. You can create a blank file as well as add new .php functions as per your theme requirements
  • Go to Themes via Appearance in the WordPress admin area. Then Activate your child theme.
  • You can visit the website to check the child theme. There will be some issues at this stage since the functions.php has not yet loaded the CSS from the parent theme.
  • Go back to the WordPress admin area and move to Editor from Appearance. Choose functions.php here.
  • You have to insert the necessary parent theme code in the functions.php file of your child theme. Update to save the changes
  • You can visit your website now to find the child theme loaded with the CSS. Now the child theme will resemble the parent theme.
