Widgets

• Create your own WordPress site on your servers. Create a subdomain exclusively for your WP site. Set up your admin account. Explore the customization tools and transform a basic template with your own artwork and images.

• Modify your WP site so it includes at least three widgets, 5 different PAGES, and a post for each page. Make sure you deactivate the comments on all of them.
