> Use heading and normal styles, modify them, create your own, then build a full report in the Chapter 5 project.

Imagine a 30-page report with 40 headings. Your manager asks for every heading to be blue instead of black. If you formatted each heading by hand, that's 40 changes. With **styles**, it's one. In this lesson, you'll learn how styles work, use the built-in heading and normal styles, change them, and create your own. Then you'll finish the chapter with a full report project.

Open the **Word sandbox** and follow along.

## What is a style?

A **style** is a saved set of formatting with a name, such as **Heading 1**: a font, size, color, spacing, and more, all in one. Apply the style, and the text gets every setting at once.

The styles are in the **Styles** gallery on the **Home** tab. Click inside a paragraph, then click a style to apply it.

The big win: when you **change a style**, every paragraph that uses it updates instantly. Format with styles, and you can restyle a whole document in seconds.

## Heading styles

The most important built-in styles are the heading styles. **Heading 1**, **Heading 2**, and **Heading 3** are built-in styles for the titles in your document:

| Style | Use it for |
|---|---|
| **Heading 1** | Main sections, such as chapter titles |
| **Heading 2** | Sections inside a chapter |
| **Heading 3** | Smaller parts inside a section |

Headings do more than look big. Word uses them to build the **Navigation Pane** (Lesson 16) and an automatic **table of contents** (Lesson 20). Keep the document title separate from section headings; use a heading style for a title only when you want it treated as a section heading. Always use heading styles for section headings instead of only making the text bold or larger.

## Normal style

After headings, the next style to know is the one for ordinary paragraphs. **Normal** is the style for body text. Most new body-text paragraphs use Normal. When you change the Normal style's font or size, paragraphs using that style update too.

To change the font of the body text, modify the **Normal** style instead of selecting every paragraph. Some heading styles may inherit settings from Normal, so check your headings after you change it.

## Modify styles

Knowing the styles is only half of it: the real power is changing them to match your document.

1. Right-click the style in the **Styles** gallery on the **Home** tab, and choose **Modify**.
2. The **Modify Style** dialog opens. Change the font, size, color, bold, italic, or alignment.
3. For spacing and indents, use the **Format** button in the dialog and choose **Paragraph**.
4. Click **OK**.

Every paragraph that uses the style updates straight away.

## Custom styles

Sometimes the built-in styles aren't enough. When you need a special look for notes or quotes, create your own:

1. Format a paragraph the way you want, or just click in any paragraph.
2. Open the **Styles** options and choose **Create a Style** or **New Style**.
3. Type a name, such as `Note`.
4. Set the formatting and choose which style it is **based on** (usually **Normal**). This means the new style starts with settings from the style you choose.
5. Click **OK**. Your style appears in the gallery, ready to use anywhere in the document.

A style is saved inside the document. If you want the same custom styles in future documents too, save the document as a template (Lesson 22).

## Common mistakes

Here are the most common traps, and how to fix them:

| Mistake | What happens | How to fix it |
|---|---|---|
| Making headings by hand with bold text | They don't show in the Navigation Pane or table of contents | Apply **Heading 1** or **Heading 2** |
| Formatting a heading directly after applying a style | That one heading looks different from the rest | Clear the extra formatting, and modify the style instead |
| Modifying a style when you meant to change one paragraph | Every paragraph with that style changes | Undo, then format only the selected text |
| Skipping heading levels | The document outline looks broken | Use the levels in order |
| Creating many near-identical custom styles | The gallery gets cluttered and confusing | Reuse and modify the styles you have |

## Exercise

Now it's time to work with styles yourself.

Click **New** in the sandbox title bar, and type these paragraphs:

- `Healthy Habits`
- `Sleep`
- `Most adults need seven to nine hours of sleep each night.`
- `Exercise`
- `Aim for at least thirty minutes of activity on most days.`
- `Tip: Small changes add up over time.`

Now do each task and press **Check**.

## Chapter project

You've now learned headers and footers, links, and styles. Time to put Chapters 1 to 5 together. You'll turn plain text into a two-page report with heading styles, a header, page numbers, a numbered list, and a link that jumps inside the document.

## What to remember

- A **style** is a named set of formatting. Apply it from the **Styles** gallery on the **Home** tab.
- **Heading 1**, **2**, and **3** give your document structure; **Normal** is for body text.
- **Modify** a style (right-click > **Modify**) to update every paragraph that uses it.
- Create **custom styles** for repeated looks, like notes or quotes.
- Format with styles, and restyling a whole document takes seconds.

That's the end of Chapter 5. In Chapter 6, you'll review documents with views, comments, and track changes.
