Read the following documentation about the child themes
Child theme inherits all the functionality and styling of it's parent theme. If you are using child theme and a theme update is applied your changes won't be lost or overwitten
You can quickly create child theme for any theme, just follow the steps given below:
1 Create a folder and name it exactly your theme name; append -child in the name. e.g. creating child theme for twentysixteen theme would be called twentysixteen-child this folder should sit beside parent theme under wp-content/themes/
2- Your child theme should have three files.
style.css
functions.php

3- In functions.php file you can override parent theme functions.
4 In style.css file you can override parent theme CSS code.
5 If you want to change header design then you have to override header.php file. For this copy header.php file of your parent theme and paste it inside your child theme folder. Now, you can modify the child theme header file as per your requirements.
6 Similarly, you can also override footer.php file in your child theme.
For more info have a look over below thread-

You need to create at-least one child-theme directory and two main files (style.css & functions.php) under child theme directory. I have given example using Twenty-Thirteen WordPress theme. Step by step explanation is given

About WordPress child theme

I have created wordpress child theme from parent theme "twentythirteen". My child theme name is "twentythirteen-child".It has following content.
/*
Theme Name: twentythirteen-child
Theme URI: http://www.example.com
Description: A Twenty Thirteen child theme
Author: WPBeginner
Author URI: http://www.example.com
Template: twentythirteen
Version: 1.0.0
*/
#import url("../twentythirteen/style.css");
Unfortunately my child theme replaces the parent theme and newly created theme is applying when i activate child theme and there is no parent theme style is applied on webpage.
How can i solve this problem?
Couple things to try:
Double check to make sure your template path in the header you posted actually goes to the twenty-thirteen theme. That could be why the base styles aren't appearing.
Your child theme needs it's own style.css - you can't import that. Read more on the WordPress Child Theme Codex Page.
Make sure you didn't copy over the entire directory into the child folder. That's a common beginner mistake.
Your child theme is supposed to override the parent theme. It supersedes any parent theme files you put into it. For example, if you put a different page.html in the root of your child theme, it would replace the page.html from the twenty-thirteen parent theme.

Require another file before require file functions.php Wordpress

Same as title, i want require file 'foo.php' before wordpress require 'functions.php' in theme. What's solution? Somebody can help me?
Use a Child Theme.
Basically you just do this:
Create a directory in your themes directory to hold the child theme.
The theme directory is wp-content/themes. You should name the
directory without any space as part of the name, and it is common
practice to use the name of the parent theme folder with “-child”
appended to it. For example, if you are making a child of the
twentyfourteen theme, your folder name would be twentyfourteen-child.
Inside, you can create a functions.php and add the code you want, you can even call other files, like your foo.php:
(...) the functions.php of a child theme does not override its counterpart
from the parent. Instead, it is loaded in addition to the parent’s
functions.php. (Specifically, it is loaded right before the parent’s
file.)
You can also create a plugin, they are loaded before functions.php, you can take a look at the loading order here: https://wordpress.stackexchange.com/questions/26537/between-functions-php-widgets-and-plugins-which-is-loaded-first

Wordpress Mezzanine Flat Theme - shortcode.php in ChildTheme

It seems that an edited copy of shortcodes.php in child-theme of mezzanine flat theme is not working (does not override the parent theme)
I tried copying the whole lib folder where shortcodes.php is located but still not working. Is there anything I need to do to make it work? Other common pages of wordpress (i.e. header and page) override smoothly on child pages.
Thanks in advance.
You can't override shortcodes.php because the child theme replace only template files
But you can create a new file, like custom_shortcodes.php with your custom shortcode, save in your child theme and then include it in functions.php ( include 'custom_shortcodes.php'; )

How to make a child theme after style.css has been customized

I am working on a theme that has already been customized. Only one file in the theme has been customized, that file is the style.css. A child theme was NOT created before doing the customizations.
I would like to make a child theme so the customizations are not lost when the theme is upgraded. How do I add the customizations in the style.css to new child theme?
Thank you.
you should check your all files and folders of theme . sometime your theme has a dynamic css file like sass, less or other .... if you have a dynamic css file, you should customize that file ....
if you haven't dynamic css files, you can customize your main css file as you want.

Wordpress, Gantry Framework, Child Theme?

Does anyone have experience with Gantry Framework?
I am wondering if it is possible to create a child theme based off of the default? Where would I put my css file and can I build off of the current css instead of starting from scratch while still separating my css from the default theme?
Apart from the usual process of creating a WordPress child theme (create a directory, with proper style.css and functions.php), Gantry requires a specific procedure.
You'll need to copy two files from the parent directory to the child theme directory, keeping the structure:
/gantry/theme.yaml
and
/includes/theme.php
Then, edit the copied theme.yaml: the parent must be your parent theme directory name.
On the theme.php, select all text and replace with this:
// Initialize theme stream.
$gantry['platform']->set(
'streams.gantry-theme.prefixes',
array('' => array(
"gantry-themes://{$gantry['theme.name']}/custom",
"gantry-themes://{$gantry['theme.name']}",
"gantry-themes://{$gantry['theme.name']}/common",
"gantry-themes://{$gantry['theme.parent']}",
"gantry-themes://{$gantry['theme.parent']}/common"
))
);
As for css, you must create this file, within your child theme directory:
/custom/scss/custom.scss
It can be formatted in either SCSS or CSS, and will override the theme's core style sheet files.
Creating a Child Theme is very easy.
All you need to do is create a directory in your theme directory, and name it something like "Gantry-child". Inside that folder, add a file called "style.css". Once this is done, you just need to add the Theme Information that tells Wordpress the Child Theme's Name, Author, and Parent Theme.
Inside the new style.css, add:
/*
Theme Name: Gantry Child
Template: rt_gantry_wp
*/
The most important part that lets Wordpress know that this is a child of the Gantry Theme is the "Template" section. This is the name of the PARENT directory in your Themes folder.
What this will do is create a new theme that inherits all of the parent theme's functions. If you also want to inherit the existing parent theme stylesheet, add to style.css:
#import url("../rt_gantry_wp/style.css");
Hopefully this should get you started. Once that's done, you can add your own header, footer, index, functions, or anything else you can think of to extend the parent theme's functionality.
Hopefully this helps get you started.
