Here We explain What is WordPress Child Theme, What is Parent Theme in WordPress, the difference between parent and child theme in WordPress, how to create child theme in WordPress step by step process.
What is WordPress Child Theme
A WordPress child theme is a theme that inherits the functionality and styling of another theme, called the parent theme. Child themes allow you to modify or add to, a preexisting WordPress theme by creating a new one with the same styling as the original but with desired changes without modifying the original code directly.
In other words, you can use your favorite theme as a parent for your WordPress child theme.
Benefits of child theme in WordPress
There are many benefits to using WordPress child themes, some of which are listed below:
• You can update your parent theme without losing any modifications that you have made in your child theme.
• You can keep the original parent theme intact, if you are having issues with your child theme, you can simply switch back to the original.
• Add new features to WordPress by creating separate themes that contain different sets of changes without affecting other installed themes.
How to create child theme in WordPress step by step
Creating a child theme is a simple four-step process:
1. Create the directory of your child theme and an empty style.css file inside <head> section of style.css:
2. Register the new child theme to WordPress:
3. Enqueue or include (using require_once()) any assets and scripts and then add CSS styles in style.css:
What should I include in my child theme
There are a number of files that you can include from your parent theme into your child theme to avoid creating everything from scratch. These files are listed below:
• Index.php (the home page template)
• Single-Xxxxxxxx.php (where Xxxxxxxx is the post type, e.g., single for posts or page for pages).
What are the things to avoid in my child theme
There are certain things that you should avoid doing in your child theme. These include:
• Don’t directly change the styles within style.css as this may overwrite your parent themes’ styles, instead create a separate CSS file for styling and enqueue it using wp_enqueue_style().
• Don’t directly change the templates within your child theme, use template files (e.g., index.php) from your parent theme as these are used to display content instead of creating new templates in your child theme.
• Never modify the source code of any file provided by WordPress or other plugins installed on your site.
What are the common mistakes made by WordPress child theme developers
Common mistakes made by beginners while creating a WordPress child theme can be broadly classified into two categories:
1. Modifying the parent theme files directly.
2. Creating their own CSS file instead of using wp_enqueue_style().
How do I debug my WordPress child theme
Debugging your WordPress child theme can be done using two methods:
1. Using Firebug to find and fix the issues
2. Checking the content of your theme which is displayed on your site and then checking style and HTML code changes in the Firebug console.
What are some common errors with WordPress child themes
Some common errors that developers face while creating WordPress child themes:
• Using the index.php file as a template, which will cause an error since WordPress looks first for a child theme and then tries to find the parent theme.
- Enqueueing style and script files that do not exist in your child theme or enqueueing them incorrectly can also lead to errors.
• Including the parent style sheet or a child theme’s style sheet in a child theme can lead to conflicts.
• Invoking the wrong action, with a wrong priority can trigger an error.
What is Parent Theme in WordPress
A parent theme is a theme that provides the foundation for another theme. The secondary or child theme inherits the fundamental code and files of the parent theme. A child theme can override any template file it wants to, including its option using an option tag while keeping the original design intact if it wishes to do so.
For this reason, parent themes are a good option for theme developers as they can provide both the framework to build on as well as design elements that are used throughout the site so users do not have to edit their original designs.
Difference between parent and child theme in WordPress
The regular blog theme that comes with WordPress is called the parent theme. The stylesheets and themes you develop yourself are child themes. Child themes override (add to or change) specific functionality in a parent theme, but don’t replace it entirely like a totally different theme would.
There are also every-which-way themes that can function as both a child theme and a stand-alone theme.
So WordPress itself is the parent in this situation. A WordPress blog that comes with 2 or 3 pre-installed themes would be a parent, and the themes you install on top of it(or add to it) are child themes.
The difference between what people often call “child themes” and “child themes” is whether they depend on another theme. Child themes can also be parent themes, which means they have a single template hierarchy, so the same file could work in both a child and a parent depending on context.
WordPress has multiple widget areas that you may add widgets. Plugins allow you to add widgets to areas not covered by default. If you want to add your own area, however, you have to create a widget plugin.
Child themes are just regular themes that inherit the functionality of another theme(the parent), so if you want your child theme to have its own widget areas then it would need its own implementation of how to display them.
A child theme is a WordPress ‘theme’ that inherits the functionality of another theme called the Parent Theme. A child theme does not replace the parent theme, rather, it extends it.
A useful analogy for this relationship would be to think of the Child Theme as a glove and the Parent-Theme as a hand. The glove can extend the functionality of the hand by adding additional fingers or features, but it still depends on the hand to exist.
WordPress child themes are a great way to start customizing your site because they allow you to make changes without affecting core files and they keep those changes from being lost when you update your theme.
You can use a child theme to change colors, layouts, add features and modify the functionality of your site. Although child themes are a great way to customize WordPress, it is important to remember that they do not change the functionality of your site — only add it.
A parent theme in WordPress (themes that you download from the internet and install on top of WordPress) contains the basic files for your site. A parent theme can be considered as a foundation for your blog, which you can further modify using child themes.
Child themes are like rooms addition in your house — you wouldn’t change or mess with the foundation of your house just because you want to add another room. You might do it if the foundation is broken, but otherwise, you would keep it separate.
A child theme inherits its styling from the parent theme 0r any other theme that may come before it in your Themes list. If you are building a website with the intent to have professional-looking margins and padding around every element on the site, then many of the styles for this would be set in the parent theme.
Child themes can come in handy when you want to make small modifications to your website that doesn’t need all of the other stylings from the parent theme, such as modifying colors or adding an image to a sidebar. You can then use a child theme for this task, while still maintaining the original styling from the parent theme.
A child theme should always load after its parent and any other theme loaded directly before it (in the ‘theme order’). This ensures that stylesheets from a parent will not affect your child theme and vice versa.
It also ensures that scripts from a parent won’t run unless they are specifically called in your child theme or another theme loaded before it.
A child theme can also be a framework for you to build your own site on top of. By creating the basic layout and functions in a child theme, you can then create further customizations as separate themes that depend on the child theme to provide its style and functionality.
This is useful if you plan to make major changes to your blog in the future, like swapping out the theme entirely.
WordPress child theme plugin
There are a lot of plugins available for WordPress which will allow you to create your own child theme very easily.
1. WP Child Theme Plugin
WP Child Theme Plugin, which besides allowing you to create your own child themes from scratch, also lets you clone any existing theme as a child theme and edit it accordingly.
2. Child Theme Configurator
Another great plugin is the Child Theme Configurator which works great. It creates a Child Theme with in few minutes.
The one big difference I have found between these two plugins is that you can create your own custom fields like colors, fonts, background images, etc. for your child themes with the Child Theme Configurator plugin while this type of customization isn’t possible with WP Child Theme plugin.
How do I update a parent or a child theme
You should keep your parent theme updated at all times so that it supports the latest WordPress features and stays secure from vulnerabilities.
Updating a parent theme is pretty straightforward. All you have to do is install the latest version of the parent theme, activate it, then run the update function that performs all updates automatically.
If your child theme is compatible with the new version of its parent them, then no further action is required on your part.
However, if the child theme is not compatible with its parent them, then the child theme will have to be edited before it can work with the new version of the parent them.
In addition to this, ensure the following:
1. Ensure you have a complete backup of your site before updating any theme or plugin.
2. Once the update is complete, check if your changes are intact in the child theme directory.
3. If you are updating any plugin, then it is advisable that you check if your new parent theme supports this plugin.
Can I use multiple parent themes with one child theme or vice versa?
Yes, you can but this will create difficulty when you need to update the parent theme, as your changes will be lost.
What is the difference between WordPress child themes and other CMS child themes
Child Themes in WordPress are similar to those of other CMS such as Joomla or Drupal. Although some of the codes used to create child themes may be different, the basic concept of using a child theme remains the same.
How to get support for a WordPress child theme
The best way to get support regarding a WordPress child theme is from its developer. In case you do not have the original source, then try asking for help from experienced WordPress users or search it online. You can also join forums to discuss your problems with other developers and get suggestions on how to resolve them.
Is a WordPress child theme recommended
Yes, WordPress child themes are recommended to everyone who wants to customize their website because by using them you could save your changes when the parent theme gets updated. Also, if an update made in a child theme breaks anything in it then you can simply revert back to the previous version in just one click.
How do I add functions to a WordPress child theme
You can add functions to a WordPress child theme by adding code in the functions.php file present in the child theme folder. This is the best way to add new functions because they will override any existing functions from the parent theme and also give you more control over your functionality. But, adding too many functions may break your website so be careful while doing this.
How do you add Google Analytics to a WordPress child theme?
There are two ways to add Google Analytics code to a WordPress child theme. The first one is where you will have to load the Google tracking code within the header file of your parent theme. Make sure that you are loading it after the wp_head() function call. The second way is through the child theme’s functions.php file.
Is it necessary to have knowledge about HTML and CSS for WordPress child theme development?
If you want to become a professional WordPress child theme developer, then yes, it is necessary to have knowledge about HTML and CSS.
Is it possible to create a full-fledged WordPress website using only child themes?
No, child themes can never be used as a replacement for WordPress themes. You will need to have a parent theme where you will write all the code and save it. After this, you will need to create a child theme that will load up your changes from the parent one. This is how both of them work together.
Where can I add a tag manager code in any WordPress child theme?
It is not possible to add a tag manager code in the WordPress child theme. If you want to add code to any of your template files, then make sure that the original developer allows it or you can always hire someone who can do this for you.
In summary, a WordPress child theme inherits from a parent theme and allows you to modify that parent theme’s functionality. You can create as many child themes as you like for a given parent theme, thus creating a family of related WordPress themes.
