B.)   Fill in the blanks using the words from the help box:

[attributes, CSS, Embedded, elements, <link>]

 

1)     HTML allows images and objects to be Embedded  and can be used to create interactive forms.

2)     External styles are defined within the <link>  element, inside the <head> section of an HTML page.

3)     CSS  is considered a very convenient and easy-to-read styling sheet.

4)     Attributes  can be used to change the colour, size, or functionality of HTML elements.

5)     HTML element  can contain formatting instructions, semantic meaning, and content.

 

 

C) Short answer type questions:

1) What do you mean by element?

Ans: An element is a fundamental building block of an HTML document. It consists of a start tag, content, and an end tag. Elements can define various types of content, such as headings, paragraphs, links, images, etc.

 

2)     What do you mean attribute?

Ans: An attribute provides additional information about an HTML element and is always included in the opening tag. Attributes consist of a name and a value and are used to modify or provide additional details about an element.

 

3)     What is internal CSS?

Ans: Internal CSS refers to the style information that is contained within the HTML document itself, typically placed in the <style> element within the <head> section. It allows styling for a specific page.

 

4)     What is External CSS?

Ans: External CSS involves placing the style information in a separate external file with a .css extension. This file is linked to the HTML document using the <link> element, providing a centralized and consistent style for multiple pages.

 

5)     What is inline CSS?

Ans: Inline CSS involves applying styles directly within the HTML tags using the style attribute. It is used for applying unique styles to specific elements on a page.

D) Long answer type questions:

1) What are the advantages and disadvantages of CSS?

Ans: Advantages of CSS include improved site maintenance, consistent styling, faster page loading, and better accessibility. Disadvantages may include browser compatibility issues, learning curve, and potential for increased complexity.

 

2) Write the characteristics of HTML?

Ans: HTML (Hypertext Markup Language) is characterized by being a markup language used for creating the structure of web pages. It consists of elements represented by tags, has a hierarchical structure, supports hyperlinks, and allows the inclusion of multimedia elements.

 

3) Write a short note on

a) Element

Ans: An element in HTML is a fundamental unit consisting of a start tag, content, and an end tag. It defines the structure and content of a document, representing various types of information like text, images, links, etc.

 

b) Attribute

Ans: An attribute in HTML provides additional information about an element and is included within the opening tag. It consists of a name and a value, modifying or enhancing the behavior of the element.

 

c) CSS

Ans: CSS (Cascading Style Sheets) is a styling language used to control the presentation and layout of HTML documents. It allows the separation of content and style, making it easier to manage the visual aspects of a website.

 

4) How we add CSS?

Ans: CSS can be added to HTML documents through three methods: inline, internal, and external. Inline CSS is applied directly within the HTML tags using the style attribute, internal CSS is placed in the <style> element within the <head> section, and external CSS is stored in a separate .css file linked to the HTML document using the <link> element.

 

5) Explain the three ways to add CSS.

Ans: The three ways to add CSS are:

 

Inline CSS: Applied directly within HTML tags using the style attribute.

Internal CSS: Placed in the <style> element within the <head> section of an HTML document.

External CSS: Stored in a separate .css file and linked to the HTML document using the <link> element. This promotes consistency across multiple pages.

 

6) What are the component of CSS?

Ans: The components of CSS include:

 

Selectors: Define which elements the styles should apply to.

Properties: Specify the visual characteristics (e.g., color, size) of the selected elements.

Values: Assign specific values to properties to determine the appearance of elements.

Declarations: Combinations of properties and values.

Rules: Consist of selectors and declarations, defining the styling for selected elements.

Stylesheet: A collection of rules that collectively define the visual presentation of a document.
