In WordPress, a Theme is a collection of files that work together to create the overall design, layout, and functionality of a website. Themes are used to customize the appearance of a WordPress website without changing the underlying code or content.
Themes include various files such as templates, stylesheets, images, and functions that work together to create the overall design and functionality of a website. WordPress comes with a default theme that can be customized, and there are thousands of free and paid themes available in the WordPress Theme Directory or through third-party providers.
Themes can be easily installed, activated, and customized in WordPress. Once a theme is installed and activated, you can customize the layout, colors, fonts, and other elements of the website through the WordPress customizer or theme settings.
Every theme has its own design, layouts, and style. You can add a new, customize or change a theme for your website from WP Admin area under Appearance > Themes.
Themes can be customized further by modifying the underlying code or by using plugins that extend the functionality of the theme.
You can also upload and install WordPress themes using an FTP client.
