Creating a link to content within a page is not exactly intuitive with the Gutenberg page editor.
My video shows you how to create a link within a page. This is commonly known as an intra-page or named target link. This allows users to tap a link and move to a different spot on the same page.
At the time of this recording only Heading elements (h1, h2, h3, h4, h5, h6) can be used as links. It’s entirely possible that by the time you see this video content types such as a single word, a list item and an image will also be able to be used as a link within a page.
