Web Designing HTML Basics: Tags, Elements, and Attributes
HTML Tags
HTML tags are special keywords enclosed within angle brackets (< >) that define the structure and semantics of a web page. They instruct web browsers on how to display the content, from headings and paragraphs to links and images. Tags are typically paired, with an opening tag (<tag>) and a corresponding closing tag (</tag>) that wraps around the content. Some notable examples include:
- Headings Tags (
<h1>to<h6>): Used to denote headings of different levels.<h1>is the highest level heading, while<h6>is the lowest.<h1>Web Design Fundamentals</h1>
- Paragraph Tag (
<p>): Defines a block of text or paragraph.<p>HTML is essential for building web pages.</p>
- Anchor Tag (
<a>): Used to create hyperlinks to other web pages or specific sections within the same page.<a href=" Example.com</a>
- Image Tag (
<img>): Displays images on a web page.<img src="path/to/image.jpg" alt="Descriptive Text">
- Division Tag (
<div>): A generic container for HTML elements, used for styling and organizing content.<div>This is a division section.</div>
Each tag has a specific purpose and affects how content is rendered in a web browser, ensuring that users can navigate and engage with the site intuitively.
HTML Elements
An HTML element consists of an opening tag, content (text or other elements), and a closing tag, forming a complete unit of markup. Elements can be nested within each other to create complex and organized structures. For example, consider the following HTML element used to create a hyperlink:
<a href=" Example.com</a>
In this snippet:
<a>is the opening tag.href=" is an attribute providing additional information.Visit Example.comis the content of the element.</a>is the closing tag.
Elements can contain other elements, creating a nested hierarchy. This structure is crucial for organizing and styling web content effectively.
HTML Attributes
Attributes provide additional information about HTML elements. They are defined within the opening tag and come in key-value pairs, separated by an equal sign. Attributes are essential for customizing elements, controlling their behavior, and enhancing accessibility. Key attributes include:
id: A unique identifier for an element, allowing styles and scripts to target it specifically.<div id="header">Welcome to My Website</div>
class: Defines one or more class names for an element, enabling multiple elements to be styled with the same CSS.<p class="text-large">This paragraph will be styled as large text.</p>
src: Specifies the source URL of an image or other media.<img src="path/to/image.jpg" alt="Descriptive Text">
href: Indicates the target URL for a hyperlink.<a href=" Example.com</a>
alt: Provides alternative text for an image when the image cannot be displayed.<img src="path/to/image.jpg" alt="Descriptive Text">
title: Offers additional information about an element when hovered over by the mouse.<a href=" title="Visit Example's Website">Visit Example.com</a>
Attributes enhance the functionality and presentation of HTML elements, making web design more dynamic and user-friendly.

Step-by-Step Guide: How to Implement Web Designing HTML Basics Tags, Elements, Attributes
Introduction to HTML
HTML (Hypertext Markup Language) is the standard markup language for creating web pages. It works by using elements to describe the structure and content of a web page.
Step 1: Setting Up Your First HTML Document
Create a Text Editor: You can use any text editing software like Notepad (Windows), TextEdit (Mac), or code editors like Visual Studio Code, Sublime Text, etc.
Create a New File: Open your text editor and create a new file. Save it with the
.htmlextension, e.g.,index.html.
Step 2: Writing Basic HTML Code
HTML Skeleton:
Here's a basic HTML template that includes all necessary elements to start any HTML document:
<!DOCTYPE html> <html> <head> <title>My First Web Page</title> </head> <body> <h1>Hello, World!</h1> <p>This is a paragraph on my first web page.</p> </body> </html>
Step 3: Understanding HTML Tags and Attributes
HTML Tags:
Document Type Declaration:
<!DOCTYPE html>- Specifies the document type and version of HTML.Root Element:
<html>- Container for all HTML elements.Head Element:
<head>- Contains meta-data about the HTML document.Title Element:
<title>- Sets the title of the web page, shown in the browser tab.Body Element:
<body>- Contains the content of the HTML document visible to the user.Heading Element:
<h1>- Represents a top-level heading.Paragraph Element:
<p>- Represents a paragraph of text.
HTML Attributes:
Attributes provide additional information to HTML elements. They are given inside the opening tag of an element.
Example:
<img src="image.jpg" alt="A beautiful flower">img: The
<img>tag is used to embed images.src: The
srcattribute specifies the path to the image.alt: The
altattribute provides alternative text for the image, which is displayed if the image cannot be loaded.
Step 4: Adding More Elements
Headings:
HTML offers six levels of headings:
<h1>to<h6>, where<h1>is the highest (largest) level and<h6>is the lowest (smallest).<h1>Heading 1</h1> <h2>Heading 2</h2> <h3>Heading 3</h3>Paragraphs:
Use the
<p>tag to add paragraphs to your web page.<p>This is the first paragraph.</p> <p>This is the second paragraph.</p>Links:
The
<a>tag creates hyperlinks to other web pages.<a href=" Example.com</a>- href: The
hrefattribute specifies the URL of the page the link goes to.
- href: The
Images:
The
<img>tag is used to display images.<img src="image.jpg" alt="Description of the image">Lists:
HTML supports ordered and unordered lists.
Unordered List:
<ul> <li>Item 1</li> <li>Item 2</li> <li>Item 3</li> </ul>Ordered List:
<ol> <li>First item</li> <li>Second item</li> <li>Third item</li> </ol>
Step 5: Styling with CSS
While HTML focuses on the structure and content, CSS (Cascading Style Sheets) is used for styling and presentation.
Inline CSS:
<h1 style="color: blue; font-size: 24px;">Styled Heading</h1>
Internal CSS:
<!DOCTYPE html>
<html>
<head>
<style>
h1 {
color: blue;
font-size: 24px;
}
p {
color: green;
font-size: 16px;
}
</style>
</head>
<body>
<h1>Styled Heading</h1>
<p>Styled paragraph.</p>
</body>
</html>
Step 6: Testing Your HTML Document
Open the HTML File:
Save your
index.htmlfile and open it in a web browser to see the result.
Summary
- An HTML document starts with
<!DOCTYPE html>. - The root element
<html>contains the rest of the document. - The
<head>element contains meta-information about the document, while<body>contains the content. - HTML elements are defined using tags, e.g.,
<h1>,<p>,<a>,<img>. - Attributes provide additional information, e.g.,
src,href,alt. - Lists can be both ordered (
<ol>) and unordered (<ul>). - CSS can be added inline, internally, or externally to style HTML elements.
Top 10 Interview Questions & Answers on Web Designing HTML Basics Tags, Elements, Attributes
1. What is HTML?
Answer: HTML (HyperText Markup Language) is the standard markup language used to create and design web pages. It uses a system of tags to structure content and determine how it is displayed in a web browser.
2. What are HTML Tags?
Answer: HTML tags are keywords surrounded by angle brackets (< and >) that tell the web browser how to format and display the content. Tags usually come in pairs: opening tags (<tag>) and closing tags (</tag>). For example, <h1> is an opening tag for a top-level heading, and </h1> is its corresponding closing tag.
3. What is the difference between an HTML element and a tag?
Answer: An HTML element includes not only the start and end tags but also the content between them. For instance, <h1>This is a heading</h1> is an HTML element where <h1> and </h1> are tags and "This is a heading" is the element's content.
4. What are attributes in HTML, and how are they used?
Answer: Attributes are additional pieces of information provided within an opening tag to alter the behavior or appearance of the element. They are set as name="value" pairs. For example, in the anchor tag <a href=" the href is an attribute specifying the URL.
5. Explain the structure of a basic HTML document.
Answer: A basic HTML document starts with the <!DOCTYPE html> declaration, followed by the <html> tag. Inside the <html> tag are two main sections: <head> and <body>. The <head> section includes meta-information like the document’s character set, title, and linked stylesheets. The <body> section contains the content of the document like headings, paragraphs, and images.
Example:
<!DOCTYPE html>
<html>
<head>
<title>My First Page</title>
</head>
<body>
<h1>Welcome to My Website</h1>
<p>This is my first web page.</p>
</body>
</html>
6. List the most commonly used HTML text formatting tags.
Answer: Commonly used HTML text formatting tags include:
<h1>to<h6>: Define headings, with<h1>being the largest and<h6>the smallest.<p>: Defines a paragraph.<br>: Inserts a line break.<strong>or<b>: Makes text bold.<em>or<i>: Italicizes text.<u>: Underlines text (though less used in modern styling).<del>: Strikethrough text.
7. What are some types of lists in HTML, and how are they used?
Answer: In HTML, there are two primary types of lists:
- Ordered lists (
<ol>): Used when the order of items is important. Each item is enclosed within an<li>(list item) tag. - Unordered lists (
<ul>): Used when the order of items doesn’t matter. Similar to<ol>, each item is enclosed within an<li>tag.
Example:
<ol>
<li>Apple</li>
<li>Banana</li>
<li>Cherry</li>
</ol>
<ul>
<li>Red</li>
<li>Yellow</li>
<li>Pink</li>
</ul>
8. How do you create a hyperlink in HTML?
Answer: Hyperlinks are created using the <a> (anchor) tag. The URL of the page the link goes to is specified in the href attribute.
Example:
<a href=" Example.com</a>
9. How do you add images to a webpage using HTML?
Answer: Images are added using the <img> tag. The source file's location is specified using the src attribute, and alt provides alternative text in case the image cannot be displayed.
Example:
<img src="image.jpg" alt="A beautiful landscape">
10. What is a block-level element in HTML? Can you give some examples?
Answer: Block-level elements start on a new line and take up the full width available. Examples include <div>, <p>, <h1> to <h6>, <ul>, and <ol>. These elements typically have top, right, bottom, and left margins and padding, and they can have a width set.
