on the white background. Figure 3.10. Use a line break to force text to shift down to the next line. [View full size image]   Alternatively, you could use a paragraph break to divide two or more portions of text into sections that can be easily formatted using various other paragraph-based formatting tools. For instance, alignments, lists, and indenting can only be performed on paragraphs. To give you an idea as to the difference between line breaks and paragraph breaks, try using two more line breaks on your text, randomly placing your cursor in the text and tapping Shift+Enter (Shift+Return on a Mac) twice each time. This effectively divides your text into three sections similar to Figure 3.11. Figure 3.11. Divide your text into three sections using line breaks.

As you can see from Figure 3.12, all the text is centered as opposed to just the highlighted section. Figure 3.12. All the text is centered as opposed to just the text that was highlighted.

Now, instead of using line breaks, use paragraph breaks to divide your text into three sections. This can be accomplished by simply placing your cursor at the point of the text block where you want to create a paragraph break and pressing Enter once. Repeat this step until your text block has been formatted into three distinct paragraphs (refer back to figure 11). Now highlight the first section of text and click the same center align button. This time, only the first section of text is center aligned. While line breaks are advantageous in a sense that you can cleanly shift your text down to the next line, paragraph breaks offer much more flexibility in that each section that is defined as a paragraph break can be formatted independently of one another. Finally, you can create headings within your paragraphs by using the Format drop-down menu within the Properties Inspector. If you look closely at the drop-down menu, you'll notice that Paragraph is currently selected. The paragraph break is actually considered a formatting option while the line break is considered a special character (which is why the line break appears within the Special Characters submenu). The advantage to this is that we can remove the paragraph formatting from a section of text by highlighting it and then choosing None from the Format drop-down menu. Of course, we don't want to do that at this point; instead we want to review the remaining options within the Format menu, specifically Heading 1Heading 6. You can use the six headings available from the Format menu as a way of adding a preconfigured style to text on your page. The browser renders each of the heading options differently so it's wise to experiment with all of them to get an understanding of the relative dimensions of each. For our example, however, we'll use Heading 3. To demonstrate this heading, add the text About Dorknozzle just above the first paragraph by placing the cursor just before the first section of text and pressing Enter to create a new paragraph break. Now add the text About Dorknozzle, highlight it, and choose Heading 3 from the Format menu. Repeat this step by adding the text Company Events under the text that appears
