Why You Should Create a WordPress Child Theme

The reason child themes exist is so you can customize a “parent” (your existing/active) theme without losing your changes and modifications when you update the parent theme.

For example, if you have directly modified the single.php file, your customizations would work fine at first.

However, when you will update your theme to a newer version of your modified theme, You will lose all of your changes and there will be no way to restore your customization.

how to create a child theme in WordPress step by step guide?

For every child theme in WordPress, two files are required.

  • functions.php
  • style.css

In the style.css file, we can add information about our child theme, e.g theme name, theme description, author name, parent theme details, tags etc.

We also need a functions.php file to register parent and child theme style sheet. With functions.php file we can also add new functions, register new navigation menus, widget areas etc.

So let’s start creating your first child theme. In this child theme, we are not going to add new widget areas, navigation menus etc. We will use our child theme to make some simple CSS changes, We will override default CSS styles.

You can use any WordPress theme as a parent theme, for this tutorial, I am going to create a child theme for the TwentySixteen theme.

Create a new folder and save it as TwentySixteen-child or you can name it anything you want such as design.

Create two new files and save them as functions.php and style.css file in our child theme folder. My child theme folder name is DesignBomb.

Now add the following information in your child theme’s style.css file and save your file.

Theme Name: Design Child
Description: A simple child theme for design blog.
Author: Tahir Taous
Version: 0.1
Template: twentysixteen

Now log in to your WordPress dashboard. Go to Appearance > Themes > Add New and upload this new child theme. You will see a new theme without any screenshot. Hover your mouse on the theme and click Theme Details button.

You will see following details for your new child theme.

In above screenshot, You can see all basic information about our child theme. Name of our child theme, who is the Author of this theme, description of child theme and you can also see This is a child theme of Twenty Sixteen. message.

We have added Template: twentysixteen in our child theme’s style.css file. This line is telling WordPress that twenty sixteen is the parent theme.

If you are using any other theme, replace TwentySixteen with your parent theme name.

Now activate your new child theme and reload your front page. You should see all the content without any styling. Don’t worry, that’s normal. This is because we have not included our parent and child theme’s style.css file

After activating new child theme Go to Appearance > Editor and select functions.php (Theme Functions) file, add the following code in functions.php file and click Update file button to save your changes.

function theme_enqueue_styles() {
    $parent_style = 'parent-style';
    wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' );
    wp_enqueue_style( 'child-style',
        get_stylesheet_directory_uri() . '/style.css',
        array( $parent_style )
add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' );

Now visit front end of your WordPress site and reload your page, You should see the normal site with all the TwentySixteen styles.

Modifying existing styles

It means our child theme is ready, It is time to customize our parent theme with new CSS styles. Now under Appearance > Editor select the style.css file. We are going to add some new styles.

Add the following style in your child theme’s style.css file and save your file.

.main-navigation .current-menu-item > a, .main-navigation .current-menu-ancestor > a {
    font-weight: 700;
    background: beige;
    border-radius: 5px;
    color: #D2691E;
    box-shadow: 2px 1px 8px #815317;

reload front end of your site and open any page. We have modified default styles for the current menu item. See screenshot below.
