Answer 1

Answer:

Gutenberg helps you create content in a more visual way than the previous TinyMCE editor. To do this, it provides a library of pre-built elements, or ‘blocks’. Each block can be added to a page or post and customized. There are blocks to handle basic components such as text and images, as well as some that provide advanced features (such as buttons and tables).
