Complete Revision Notes, Accurate Board Exam Facts & Important Practice Questions
1. What is a Style? & Advantages
Exam Definition: A Style is a set of formats (such as font name, size, color, text alignment, and borders) saved under one name. Instead of changing fonts or margins manually line by line, you can apply a style to format the selected text or page in a single click.
Why Should We Use Styles? (Advantages)
1. Consistency Across the Document
It keeps headings, subheadings, and body text identical throughout your project or report.
2. Saves Time & Effort
You do not have to format every paragraph manually. A whole chapter can be formatted in seconds.
3. Fast & Automatic Updating
If you change the font in a style, every paragraph using that style updates automatically throughout the document.
4. Helps in Automatic Table of Contents
Using proper Heading styles allows LibreOffice Writer to build an automatic Table of Contents (TOC).
2. Six Categories of Styles in LibreOffice Writer
CBSE syllabus focuses on these 6 style categories available in LibreOffice Writer:
1. Page Style
Controls the overall page structure: page size (A4, Letter), margins, orientation (Portrait or Landscape), headers, footers, and page borders.
Example: Creating an A4 Landscape page without any header/footer for a cover page.
2. Paragraph Style
Controls entire paragraph formatting: text alignment (Left, Center, Right, Justified), line spacing, tab stops, indents, and paragraph borders.
Example: Setting all main headings to bold, 18pt, and center-aligned.
3. Character Style
Formats specific words or letters inside a paragraph without changing the formatting of the rest of the text.
Example: Making a single keyword red and bold inside a regular black paragraph.
4. Frame Style
Formats graphic elements, text boxes, and inserted pictures: controlling outer borders, text wrapping, and spacing around frames.
Example: Putting a neat border and text-wrap around an image diagram.
5. List Style
Formats numbered and bulleted lists: setting bullet shapes, numbers (1, 2, 3 or i, ii, iii), and list indents.
Example: Applying a Roman numeral list style with custom tab indentation.
6. Table Style
Formats tables: managing cell borders, alternating row colors, cell padding, and table header rows.
Example: Applying a pre-set table layout with a shaded top header row.
