Preparing To Add Css In WordPress
Before adding custom CSS to WordPress, some preparation is important. It helps keep your site safe and organized. Preparing makes the process smoother and avoids mistakes. You will learn how to access the dashboard, choose the right theme, and back up your site.
Accessing The WordPress Dashboard

Choosing A Child Theme
A child theme lets you change the look without breaking the original theme. Use a child theme to keep your custom CSS safe during updates. Create or activate a child theme before making any CSS changes. This keeps your site stable and easy to fix.
Backing Up Your Site

Using The WordPress Customizer For Css

Previewing Changes Live

Editing Css Safely

Saving And Testing Changes
After editing, click the Update File button. Wait for the confirmation message to appear. Then, open your website in a new tab. Refresh the page to see the changes. If something looks wrong, revert to your backup file. This keeps your site safe from errors.
