margin-right: 10px;

headings and the following paragraphs is now much smaller, but the space
between individual paragraphs remains unchanged. This is because the default
bottom margin still occupies the space between paragraphs.

paragraphs, and headings. The exercise also demonstrated the importance of checking the size of adjacent
vertical margins when trying to adjust the distance between block-level elements.
