Html Tags
HTML tags are the building blocks of any web page. They are used to define and structure content, and they tell the web browser how to display text, images, and other elements. Every HTML tag is enclosed in angle brackets, like <tagname>, and most tags come in pairs: an opening tag and a closing tag. The closing tag looks like the opening tag but includes a forward slash, for example, <p> and </p> for a paragraph. Tags are used to mark up elements like headings (<h1> to <h6>), paragraphs (<p>), links (<a>), images (<img>), lists (<ul>, <ol>, and <li>), and more. One of the first tags in any HTML document is the <!DOCTYPE html> declaration, which tells the browser you're using HTML5. After that, everything is wrapped inside the <html> tag, which serves as the root of the document. Inside the <html>
tag, the content is divided into two main sections: the <head> and the <body>. The <head> contains meta information, like the page title (<title>), character encoding (<meta charset="UTF-8">), links to CSS files (<link>), and scripts (<script>). The <body> tag contains all the content users see and interact with, such as text, images, videos, and forms. Within the body, you use tags like <h1> to define main headings and <p> to create paragraphs of text. Links are made with the <a> tag, where you use the href attribute to specify the URL, like <a href="https://example.com">Visit</a>. Images are added using the <img> tag, which is a self-closing tag and includes attributes like src (the path to the image) and alt (alternative text for accessibility). Lists are created using <ul> for unordered lists (with bullet points) and <ol> for ordered lists (with numbers), and each list item goes inside an <li> tag. For structure and layout, HTML uses tags like <div> and <span>, which don’t add any visual style by default but are commonly used with CSS for design purposes. There are also semantic tags like <header>, <nav>, <section>
, <article>, and <footer> which help define the role of different parts of a web page, making it more meaningful and accessible to search engines and screen readers. Tables can be built using <table>, with rows inside <tr>, headers in <th>, and data cells in <td>. Forms, which allow user input, involve several tags like <form>, <input>, <textarea>, <button>, <label>, and <select>. Each HTML tag plays a specific role in organizing and presenting content, and knowing which tag to use—and how to use it properly—is a key part of web development. Overall, HTML tags are simple but powerful. With just a few of them, you can create a fully structured web page, and by combining them with CSS and JavaScript, you can bring your website to life.
