Most word processors automatically create new lines for you, so you will only need to use the Enter or Return key to end paragraphs. If you're ending a paragraph that will be followed by a new heading, hit the Enter or Return key two times.
Use bold or italic text to display emphasis in documents on the Web. Do NOT use underlined words. Underlined text indicates hyperlinks. For consistency, please keep your paragraphs left-aligned. For more than one column of text, please place your text in a table.
