Parents should also know that good HTML practice improves performance in both written and practical exams. These HTML notes Class 10 CBSE focus on exam-relevant concepts only.
Structure of an HTML Document
An HTML document has a fixed basic structure. This structure tells the browser how to display the web page.
Basic parts of an HTML page:
<html> – starts and ends the document
<head> – contains title and page information
<body> – contains visible content
Students must remember this order, as questions often test the basic layout.
Common HTML Tags and Attributes
HTML tags are used to create content on a web page. Attributes provide extra information about a tag.
Frequently used tags:
Headings (<h1> to <h6>)
Paragraph (<p>)
Line break (<br>)
Horizontal line (<hr>)
Common attributes include:
text, bgcolor, align, width, height
Parents can help by asking students to explain what each tag does in simple words.
Lists in HTML
Lists are used to arrange items neatly.
List Type
Tag Used
Ordered list
<ol>
Unordered list
<ul>
List item
<li>
Lists are commonly asked in both theory and practical exams.
Images and Tables
Images make a web page attractive, while tables organise data.
Images use the <img> tag with attributes like source and size
Tables use <table>, <tr>, <th>, and <td>
Students should practise creating simple tables as they are often part of lab tests.
HTML Forms (High Exam Weightage)
Forms are used to collect user information and are very important for exams.
Common form elements:
Text box
Radio button
Checkbox
Password field
Exam tip:
Forms questions usually carry more marks, so students should practise them carefully.

Unit 2 (Part B) – CSS Basics
CSS is used to improve the look and feel of a web page. In CBSE Class 10, students are not expected to do advanced designing. The focus is only on basic styling. This unit helps students make simple HTML pages more neat and presentable. Parents should know that clean design and correct use of CSS can help students score better in practical exams.
What Is CSS?
CSS stands for Cascading Style Sheets. It controls how text, colours, and layout appear on a web page. Instead of changing each tag again and again, CSS allows students to apply styles easily.
Students should remember that CSS works along with HTML, not separately.
Types of CSS Used in Class 10
At CBSE level, only two types of CSS are required.
Inline CSS
Style is written inside an HTML tag
Used for small changes
Easy to understand for beginners
Internal CSS
Style rules are written inside the <style> tag
Applies styling to the whole page
More organised than inline CSS
Students should practise both types for exams.
Font and Text Styling
CSS helps control how text looks on a web page.
Common text styles include:
Font size
Font colour
Font family
Text alignment
Clear and readable text is important for exam-based web pages.
Background and Colour Styling
Background styling makes a page visually better.
Basic background options:
Background colour
Border style
Page width and height
Students should avoid overuse of colours and keep the design simple.
Exam-Focused Styling Tips
Use limited colours
Keep font size readable
Focus on correctness, not decoration
Simple and clean styling is enough to score well in CBSE practical exams.
