HTML Guide
Introduction to HTML
HTML (HyperText Markup Language) is the standard language for creating web pages and web applications. It describes the structure of web pages using markup. It defines the structure and content of a web document by using a system of tags and attributes, which browsers interpret to display text, images, multimedia, and interactive forms.
Basic Structure of an HTML Document
html
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<h1>This is a Heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
<!DOCTYPE html>: Declares the document type and version of HTML.
<html>: The root element of an HTML page.
<head>: Contains meta-information about the HTML document (e.g., title, links to stylesheets).
<title>: Sets the title of the web page.
<body>: Contains the content of the HTML document, such as text, images, links, etc.
Common HTML Tags
1.Headings: Defined with <h1> to <h6> tags.
html
<h1>This is a Heading 1</h1>
<h2>This is a Heading 2</h2>
2. Paragraphs: Defined with the <p> tag.
html
<p>This is a paragraph.</p>
3. Links: Created with the <a> tag.
html
<a href="https://www.example.com">This is a link</a>
4. Images: Inserted with the <img> tag.
html
<img src="image.jpg" alt="Description of image">
5. Lists: Ordered lists (`<ol>`) and unordered lists (`<ul>`) contain list items (`<li>`).
html
<ul>
<li>Item 1</li>
<li>Item 2</li>
</ul>
<ol>
<li>First item</li>
<li>Second item</li>
</ol>
6. Tables: Defined with the `<table>` tag, and rows are defined with `<tr>`. Table headers are defined with `<th>` and table data with `<td>`.
html
<table>
<tr>
<th>Heading 1</th>
<th>Heading 2</th>
</tr>
<tr>
<td>Data 1</td>
<td>Data 2</td>
</tr>
</table>
7. Forms: Used for user input and defined with the `<form>` tag.
html
<form action="/submit" method="post">
<label for="name">Name:</label>
<input type="text" id="name" name="name">
<input type="submit" value="Submit">
</form>
HTML Attributes
Attributes provide additional information about HTML elements. They are always included in the opening tag.
html
<a href="https://www.example.com" target="_blank">Example Link</a>
<img src="image.jpg" alt="Description of image" width="500" height="600">
href: Specifies the URL of the page the link goes to.
target: Specifies where to open the linked document.
src: Specifies the path to the image.
alt: Provides an alternative text for the image.
width and height: Specifies the width and height of the image.
Semantic HTML
Semantic HTML introduces meaning to the web page rather than just presentation. Examples include:
html
<header> ... </header>
<nav> ... </nav>
<main> ... </main>
<article> ... </article>
<aside> ... </aside>
<footer> ... </footer>
These tags help with SEO and accessibility.
HTML Comments
Comments are used to insert notes into the HTML code, which are not displayed in the browser.
html
<!-- This is a comment -->
Doctype Declaration
The <!DOCTYPE html> declaration must be the very first thing in your HTML document, before the `<html>` tag. It ensures that the browser renders the page in standards mode.
Best Practices
- Always use lowercase for HTML tags and attributes.
- Quote attribute values.
- Properly nest elements.
- Use semantic tags to enhance readability and accessibility.
Conclusion
HTML is the foundation of web development. Understanding its basic structure, elements, and best practices is crucial for creating well-structured and accessible web pages.
