HTML Basics

I. Introduction

HTML (Hypertext Markup Language) is the standard markup language used for creating web pages. It provides the structure and layout for the content on a webpage. HTML uses a set of elements and tags to define the different parts of a webpage and their attributes.

A. Importance of HTML in web design

HTML is the backbone of web design. It allows web developers to create structured and organized web pages that can be easily understood by web browsers. Without HTML, the web would not exist as we know it today.

B. Fundamentals of HTML

HTML is based on a simple syntax that consists of opening and closing tags. Tags are used to define elements, such as headings, paragraphs, lists, images, and links. Attributes provide additional information about elements, such as the source of an image or the target of a link.

II. Elements

A. Definition and purpose of HTML elements

HTML elements are the building blocks of web pages. Each element represents a different part of the content, such as headings, paragraphs, lists, images, and links. Elements are defined using tags.

B. Examples of commonly used HTML elements

Some commonly used HTML elements include:

• <h1> to </h1><h6>: Headings of different levels
• <p>: Paragraph
• </p><ul>: Unordered list
• <ol>: Ordered list
• <img>: Image
• <a>: Link

III. Tags

A. Definition and purpose of HTML tags

HTML tags are used to define elements and their attributes. Tags consist of opening and closing brackets (< and >), with the element name inside. Opening tags are used to start an element, and closing tags are used to end it.

B. Examples of commonly used HTML tags

Some commonly used HTML tags include:

• <h1> to </h1></a><h6><a>: Headings of different levels
• <p>: Paragraph
• </p></a><ul><a>: Unordered list
• </a><ol><a>: Ordered list
• <img>: Image
• </a><a>: Link

IV. Attributes

A. Definition and purpose of HTML attributes

HTML attributes provide additional information about elements. They are added to the opening tag of an element and consist of a name and a value, separated by an equals sign (=).

B. Examples of commonly used HTML attributes

Some commonly used HTML attributes include:

• src: Specifies the source of an image
• href: Specifies the target of a link
• alt: Specifies alternative text for an image
• style: Specifies inline CSS styles

V. Paragraph

A. Creating paragraphs in HTML

Paragraphs are created using the <p> tag. Text placed between the opening and closing </p><p> tags will be displayed as a paragraph on the webpage.

B. Formatting text within paragraphs

Text within paragraphs can be formatted using CSS styles or inline styles. Common formatting options include changing the font size, color, and alignment.

VI. Headings

A. Different levels of headings in HTML

HTML provides six levels of headings, from </p><h1> (the highest level) to </h1></a><h6><a> (the lowest level). Headings are used to structure the content and provide hierarchy.

B. Formatting and styling headings

Headings can be formatted and styled using CSS styles or inline styles. Common styling options include changing the font size, color, and alignment.

VII. Line Breaks

A. Creating line breaks in HTML

Line breaks can be created using the <br> tag. The <br> tag is a self-closing tag, which means it does not require a closing tag.

B. Usage and best practices

Line breaks should be used sparingly and only when necessary. They are typically used to create space between lines of text or to separate content into different sections.

VIII. Horizontal Rule

A. Creating horizontal rules in HTML

Horizontal rules can be created using the <hr> tag. The <hr> tag is a self-closing tag, which means it does not require a closing tag.

B. Styling and customization options

Horizontal rules can be styled and customized using CSS styles or inline styles. Common customization options include changing the color, width, and style of the rule.

IX. Lists

A. Creating ordered and unordered lists in HTML

Ordered lists are created using the </a><ol><a> tag, and unordered lists are created using the </a><ul><a> tag. List items are defined using the <li> tag.

B. Nesting lists and adding list items

Lists can be nested inside other lists by placing the nested list inside an </li></a><li><a> tag. List items can contain other HTML elements, such as paragraphs, images, and links.

X. Formatting

A. Formatting text in HTML using tags

HTML provides a set of formatting tags that can be used to change the appearance of text. Some commonly used formatting tags include <strong> for bold text, <em> for italic text, and `` for underlined text.

B. Examples of commonly used formatting tags

Some commonly used formatting tags include:

• <strong>: Bold text

• ``: Underlined text

XI. Color Codes

A. Understanding color codes in HTML

HTML uses color codes to specify the color of elements. Color codes can be represented in different formats, such as hexadecimal (#RRGGBB), RGB (rgb(R, G, B)), or color names.

B. Using color codes to style elements

Color codes can be used in CSS styles or inline styles to change the color of elements. They can be applied to text, backgrounds, borders, and other elements.

XII. Font

A. Changing font styles and sizes in HTML

HTML provides a set of font-related tags that can be used to change the font style, size, and other properties. Some commonly used font tags include `and`.

B. Using web-safe fonts and custom fonts

XIV. Email

A. Creating email links in HTML

Email links are created using the </a><a> tag with the href attribute set to mailto: followed by the email address. Additional attributes, such as subject and body, can be used to pre-fill the email subject and body.

B. Adding subject lines and body text

Subject lines and body text can be added to email links using the subject and body attributes. These attributes are added to the </a><a> tag.

XV. Images

A. Adding images to HTML pages

Images are added to HTML pages using the <img> tag. The src attribute is used to specify the source of the image, and the alt attribute is used to provide alternative text.

B. Specifying image sources and alt text

The src attribute is used to specify the source of the image. This can be a relative or absolute URL. The alt attribute is used to provide alternative text for the image, which is displayed if the image cannot be loaded.

XVI. Image Link

A. Creating image links in HTML

Image links are created by wrapping an <img> tag with an </a><a> tag. The href attribute of the </a><a> tag is used to specify the target of the link.

B. Linking images to external websites and internal pages

Analogy

HTML is like the blueprint of a house. It defines the structure and layout of the house, such as the walls, doors, and windows. Just as a blueprint provides instructions for builders to construct a house, HTML provides instructions for web browsers to display a webpage. The elements and tags in HTML are like the different components of a house, such as the rooms, furniture, and decorations. By using HTML, web developers can create well-organized and visually appealing web pages, just like architects and builders create beautiful houses using blueprints.
