XHTML elements

Here's a tutorial on XHTML elements:

XHTML (Extensible Hypertext Markup Language) elements are similar to HTML (Hypertext Markup Language) elements, but they have a more structured and strict syntax. XHTML elements are defined using XML (Extensible Markup Language) syntax, which requires all elements to be properly nested and closed.

XHTML elements are used to define the structure and content of web pages. Here are some of the most commonly used XHTML elements:

<html> The <html> element is the root element of an XHTML document, and it contains all other elements in the document.
<head> The <head> element contains metadata about the document, such as the title of the document, links to stylesheets, and scripts.
<body> The <body> element contains the main content of the document, such as text, images, and multimedia.
<h1> - <h6> The <h1> to <h6> elements are used to define headings in the document, with <h1> being the largest heading and <h6> being the smallest.
<p> The <p> element is used to define paragraphs of text in the document.
<a> The <a> element is used to create hyperlinks to other pages or resources. The href attribute is used to specify the URL of the link.
<img> The <img> element is used to insert images into the document. The src attribute is used to specify the URL of the image, and the alt attribute is used to provide alternative text for users who cannot view the image.
<ul> and <li> The <ul> and <li> elements are used to create unordered lists. The <ul> element defines the list, and each item in the list is defined using an <li> element.
<ol> and <li> The <ol> and <li> elements are used to create ordered lists. The <ol> element defines the list, and each item in the list is defined using an <li> element.
<table>, <tr>, <td> The <table>, <tr>, and <td> elements are used to create tables in the document. The <table> element defines the table, the <tr> element defines a row in the table, and the <td> element defines a cell in the table.

These are just a few examples of the many XHTML elements that can be used to create structured and well-formed web pages. By using XHTML elements properly, you can create web pages that are compatible with XML-based technologies and that are easy to maintain and update.
