Creating A Child Theme
Creating a child theme in WordPress allows you to add custom code safely. This method preserves your changes during theme updates. It’s a simple way to customize your site without risking losing custom edits.

Steps To Create A Child Theme
First, make a new folder. Name it after your theme and add “-child”. Inside, create a style.css file. Write your custom styles here. Next, create a functions.php file. This is for custom code. Connect your child theme to the parent theme. Add this line in style.css: @import url("../parent-theme/style.css");.
Activating Your Child Theme
Go to your WordPress dashboard. Click on Appearance, then Themes. Find your child theme. Click Activate. Your child theme is now active. It runs alongside your parent theme. Custom changes appear live. You can now add more code safely.

Using The WordPress Theme Editor
To add custom code, first, access the WordPress Theme Editor. Start by logging into your WordPress dashboard. Find the menu on the left side. Click on Appearance and then click on Theme Editor. A new page will open. Here, you can see the theme files. Each file has a different purpose. Choose the right file to edit.
Editing theme files needs care. Always make a backup before changes. This keeps your site safe. Use Child Themes to avoid losing edits. A child theme is like a copy. It lets you change things without harm. When editing, check the code twice. Small mistakes can break your site. Use comments to note changes. This helps you remember what you did.
Adding Custom Css
Customizing a WordPress theme with CSS enhances its look. Access the theme editor in the dashboard. Paste your CSS code into the “Additional CSS” section. Save changes to view the updates.
Inline Css Vs. External Stylesheets
Inline CSS is written inside HTML tags. It affects only one element. This method is quick for small changes. But it can make your code messy. External stylesheets keep CSS in separate files. These files are linked to HTML. They help keep code clean and organized. For bigger projects, external stylesheets are best. They make managing styles easier.
Best Practices For Custom Styles
Use clear names for CSS classes. This helps identify styles quickly. Avoid using IDs for styling. They can create conflicts. Group similar styles together. This makes reading easier. Use comments in your CSS. Explain what each section does. It helps others understand your code. Test styles on different devices. Make sure they look good everywhere.
