Unit One: Introduction to HTML
The Basics of HTML
HTML (Hypertext Markup Language) is the standard language used for creating web pages. It provides the structure and content of a webpage by using various tags and attributes. Each HTML document is composed of a series of elements, which are represented by opening and closing tags. The basic structure of an HTML document includes the doctype declaration, the head section, and the body section.
Creating the Structure with HTML Elements
HTML elements are the building blocks of web pages. They are represented by tags that define different parts of a webpage. For example, the <h1> tag is used to define a heading, the <p> tag is used to define a paragraph, and the <a> tag is used to define a hyperlink. HTML elements can also have attributes, which provide additional information about the element. For instance, the <a> tag can have the \"href\" attribute to specify the URL of the link.
Formatting Text and Adding Images
HTML allows you to format text using various tags. For example, the <b> tag is used to make text bold, the <i> tag is used to make text italicized, and the <u> tag is used to underline text. You can also add images to your web pages using the <img> tag, which requires the \"src\" attribute to specify the image file and the \"alt\" attribute to provide alternative text in case the image cannot be displayed.
Organizing Content with Lists and Tables
HTML provides tags for creating ordered lists (<ol>), unordered lists (<ul>), and definition lists (<dl>). These list tags allow you to present information in a structured manner. Additionally, HTML includes the <table> tag for creating tables. Tables consist of rows (<tr>) and columns (<td>), and the <th> tag is used for table headers. This allows you to display tabular data in an organized format.
Linking Web Pages with Hyperlinks
Hyperlinks are fundamental to the interconnected nature of the World Wide Web. HTML provides the <a> tag to create hyperlinks. The \"href\" attribute is used to specify the URL of the linked web page. You can also use relative URLs for linking to other pages within your website. Additionally, HTML offers the <nav> and <footer> tags to define the navigation and footer sections of a webpage respectively.
Structuring Web Pages with Divs and Spans
HTML provides the <div> and <span> tags to group and style elements. The <div> tag represents a division or section in a webpage, while the <span> tag is used to apply specific styling to a portion of text within an element. These tags allow you to organize and style your webpage content in a more flexible manner.
Conclusion
HTML is the foundation of web development and understanding its basics is essential for anyone looking to create web pages. By using HTML elements, formatting text, organizing content, and linking web pages, you can create well-structured and visually appealing web pages. With practice and further exploration of HTML, you can enhance your web development skills and create more complex websites.
