Customizing your Site
Using the Customizer, you can modify certain parts of your website. When you click on the Customize menu option you’ll be shown the various theme options that you can change. Depending on the theme that is currently in use, you may see more or less options than those displayed in the following image.
Clicking the small arrows will open and close each of the panels, giving you access to each of the various options. You’ll find that some of the options in the Customize screen are also available via other menu options. As an example, you can change the Site Title and Tagline using the General option under the Settings menu.
As you make your changes on the left-hand side of the Customize screen, the theme preview on the right-hand side is automatically updated.
Until you click the Save & Publish button, only the theme preview is updated, not the theme on your live site.
To help with testing your site across various devices, the Customizer also allows you to preview your site in mobile, tablet and desktop views. At the bottom of the Customizer panel, click one of the view icons ( ) to change your site preview so that you can get an idea of how it will display on a regular desktop, a tablet or smartphone device.
