Report of return and shift + return, the <p> element and the <br> element

This report is the result of a study of how to best place a blank line within a single text box element.

It is a demonstration of return and shift + return, the Paragraph element and the Break (forced newline) element.
This is a verification of how paragraph elements and forced line break elements are generated by pressing the return or shift key when editing text.

If you understand HTML, you should be able to understand the meaning and value of this experiment and its application.

The best answer is also included at the end, so please watch it.

If there are any requests that this verification sample and the ideal editorial policy should be described in more detail, I will add them when I have more time to spare.
