Here is a paragraph of text.
This is the same paragraph, but a new line started because of the br tag.

Here is a second paragraph. Note that the gap between this paragraph and the previous one is larger than the gap caused by the br tag.

Note how the amount of space between words in the source makes no difference to how the text is rendered in the browser.
