There are two ways to modify a WordPress theme: the fast way and the smart way.
The fastest way is to edit the files of the theme by selecting the files with the “Appearance”, “Editor” menu option. The drawback is that when the theme is updated your customizations will be wiped out. The update process will overwrite the files you changed, so all of your changes will disappear.
A better way of modifying a theme is to create a “child theme”. This has two advantages:
- By creating a child theme you maintain the changed files in a separate theme (the child theme) so when you update the original (parent) theme your customization is not affected.
- You keep a separate copy of your changes in the child theme, so you can always easily find your modifications without reading through the theme files. You will only maintain the changed lines from the style.css file and your functions.php file will only include your custom functions. Your images folder will only contain your image files.
In this tutorial we will create a child theme for the Simplify theme
- Use your favorite FTP application (mine is FileZilla) and create a folder for the child theme in the wp-content/themes folder
- Right click the “themes” folder and select “Create directory”
- Enter the name of the folder of the child theme
- Double click the new folder name to open it
Right click the empty area of the directory listing and select “Create new file”
Enter style.css as the file name and click OK
- Log into your site as administrator,
- Navigate to the Theme Editor,
- In the upper right corner select the child theme and click the Select button
- In the upper right corner click the “Stylesheet” to open the style.css file
Copy the following to the editor window.
- Enter the name of the new child theme to the “Theme Name” line
- Replace “simplify” with the name of the original theme folder.
/* Theme Name: Simplify Child Theme URI: http://example.com/ Description: Child theme for the Simplify theme Author: Your name here Author URI: http://example.com/about/ Template: simplify Version: 0.1.0 */
@import url("../simplify/style.css");
- Click the “Update File” button to save your changes
Select and activate the new child theme
- On the left side select “Appearance” , “Themes”
- On the theme list click the empty image of the new child theme you just created
- Click the “Save & Activate” button to activate the child theme
