What Is A WordPress Child Theme ?what_is_a_child_theme

WordPress Child Theme is basically an add-on theme that inherits all the styling, functions, code and functionality from the main theme called the parent theme.

Child themes are used by the theme developers as well as by bloggers who wants to experiment and modify their themes.

You can create child theme of any WordPress theme whether paid or free, no matter.

How A Child Theme Works Actually ?

Let us assume that you are using a child theme on your blog. Now when your website loads on user’s browser, WordPress will check your child theme first. If any custom changes and modified files are found – they will be loaded. Any other missing file will be loaded from the parent theme.

In simple words, you only use those files and templates in your child theme which you want to modify. All other files and code will be pulled from the parent theme. No need to re-write the whole theme-files.

As a child inherits his/her genes from his parents, similarly the child theme inherits its functioning from the parent theme.

#Easy & Safe Updates

You can update your theme easily and safely without losing your custom modifications.Your changes and modifications will remain preserved and safe, even after updating your theme.

#Easy To Restore

Dealing with codes can be very annoying sometimes.

Just misplace a small “semicolon” from its place and boooom...your blog will crash the very next moment.

But if you are using a child theme, dealing with the problem become a lot easier. Just deactivate the child theme and your blog will shine again.

After correcting the code in the child theme, you can activate it again.

#Organize All Modifications In A Neat-&-Clean Way

Modifying the original theme files can be very messy as there are thousands lines of long and complex code.

A modern WordPress theme consist of bunch of different files ( PHP files, HTML files, CSS files, Javascripts etc.) Now, what happens generally – you make different changes to different files, some here-some there.

Tracking back all these codes of lines is not-so-easy. Organizing and maintaining your changes becomes difficult.

But if you use a child theme, all the changes will be in a separate set of files (child theme’s folder) with neat and modified code only.

If you use a child theme – all your modifications can be found in your child theme’s files. Easy to manage, easy to locate.

#Stay Safe – Always

While using child theme, you will always have a backup – parent theme.

If you skip some code for something while editing your child theme, don’t worry, WordPress will pick those missing files and code from the parent theme. Just focus on the files you want to modify and rest will be extracted from the parent theme.

You can learn and experiment with child themes safely. If anything goes wrong, you can turn off the child theme and switch back to the original theme anytime.

#Easy To Create

Child themes are really easy to create. You do not need to add all the files as there in a complete original theme. You just need to add and edit your modifications. No fuss, no muss.
