🗺️ Chapter Roadmap

01. Introduction to Styles

What is the problem with Manual Formatting?

In manual formatting, the user selects different parts of a document such as a page, paragraph or words and applies formatting effects using the formatting toolbar.

If the same formatting is required at many places, the formatting steps have to be repeated for every part of the document.

⚠️ Exam Point

Creating a large report with consistent formatting becomes difficult when manual formatting is used.

Why do we use Styles?

Definition of Style ⭐

A Style is a collection of all formatting information which you want to save and then apply on the document.

Example — Title Style

A Title Style can store formatting information such as:

🧠 Remember:

Once a style is created, it can be applied consistently to different titles. If the title format needs to change, the style can be updated instead of formatting every title separately.
