Key Features, Purposes, and Different Versions of HTML + Syntax Structure

Ans 1.

Key Features and Purpose of HTML

HTML (HyperText Markup Language) is the foundational language for creating webpages and web applications. Its key feature is that it uses predefined tags to structure content such as text, images, links, tables, and multimedia. HTML enables web browsers to interpret and display content in a consistent manner across different platforms. The purpose of HTML is to provide the structural framework of a webpage, allowing developers to organize information logically. It supports hyperlinks, enabling navigation between pages, and offers semantic tags such as <header>, <footer>, and <article>, which help improve readability and SEO. HTML works in combination

Q2. How do you create and utilize tables in HTML? What is the function of various list types and text formatting tags?        3+7

Ans 2.

Tables in HTML + List Types + Text Formatting Tags

Creating and Using Tables in HTML

Tables in HTML help organize data into rows and columns, making it easy to present structured content such as schedules, comparison charts, fees, records, and inventory lists. The <table> element contains the entire structure. Inside it, <tr> represents each row, <td> represents data cells, and <th> represents headers. These tags allow developers to divide information clearly. A table begins with defining columns using <th> inside the first <tr>, followed by additional rows containing <td> cells.

 

Q3. What is CSS, and how can you define and implement basic CSS styles in an HTML document? 5+5    

Ans 3.

CSS Definition + Implementing Basic Styles in HTML

Definition and Purpose of CSS

CSS (Cascading Style Sheets) is a style language used to control the visual appearance, layout, and formatting of HTML elements. While HTML structures content, CSS determines how that content should look—such as color, font, spacing, alignment, borders, backgrounds, and responsiveness. CSS enables separation of structure and design, making webpages more maintainable. The term “cascading” refers to the priority order in which styles are applied, meaning multiple

4. How can text be inserted and aligned in HTML? How do you add images and links to a web page? 10

Ans 4.

Inserting and Aligning Text in HTML

Text insertion in HTML is performed using structural tags such as <h1> to <h6> for headings, and <p> for paragraphs. These tags help organize content and define hierarchy on a webpage. Headings improve SEO and readability, while paragraphs allow developers to create well-structured content blocks. The <span> tag is used for inline text formatting, while <div> is used for block-level text organization. HTML also provides semantic tags such as <strong>, <em>, <cite>, and <blockquote> to give meaning and emphasis to specific portions of text.

Text alignment in HTML is controlled primarily through CSS, but older versions of HTML included the align

 

Q5. What is the structure of HTML forms, and what are the different form elements, input types, and attributes? How do these components improve user interaction? 8+2    

Ans 5.

Structure of HTML Forms, Form Elements, Input Types, Attributes & User Interaction

Structure of HTML Forms

HTML forms allow users to enter and submit data to a server. They are created using the <form> tag, which serves as a container for various input fields and controls. A form includes essential attributes such as action, which defines where the data should be sent, and method, which specifies how data is transmitted—typically using GET or POST. The form structure usually follows a pattern of label-control pairs wrapped in <label> and <input> tags. For example:

<form

 

Q6. What are the basic syntax rules, data types, and operators in JavaScript? How is JSON used for data representation, and how can it be parsed or converted to a string in JavaScript? 5+5 

Ans 6.

JavaScript Syntax, Data Types, Operators + JSON Parsing/String Conversion

Basic Syntax Rules in JavaScript

JavaScript is a scripting language used to add interactivity and dynamic behavior to webpages. Its syntax resembles C-style programming languages. Statements end with semicolons, though they are optional due to automatic insertion. Variables can be declared using var, let, or const, where let and const support block scope. JavaScript is case-sensitive, meaning variable names like Name and name are treated differently. Curly braces {} define code blocks, and parentheses () enclose
