HTML files are a markup language used to create web pages. HTML stands for Hypertext Markup Language, which is the basis of web programming. HTML files use markup tags to describe the structure and content of the document and hyperlinks to connect different files and resources.
HTML files follow a set of rules that determine how each element in the document behaves and displays. HTML markup tags are enclosed in angle brackets, for example, and
. These tags can be used to format text, add images and other media elements, create hyperlinks, and define page structure.HTML documents consist of markup tags and text. Markup tags define elements of a document, such as headings, paragraphs, and images, while text makes up the content of these elements. Text can contain letters, numbers, symbols, and any other characters.
HTML files can also contain script code, which can be written using JavaScript and embedded into the page to enhance its functionality. Script code can perform actions that interact with the page, such as validating form data, dynamically updating page content, and handling user input events.
When creating HTML files, you can use a text editor or specialized web development tools. Text editors allow you to manually create HTML code, while web development tools provide visual interfaces and more advanced features such as code auto-completion and debugging.
HTML files can be viewed and accessed through a web browser. When a user accesses a web page containing an HTML file, the browser parses the HTML code and converts it into a visual page.
In short, HTML files are one of the foundations of Web programming. It is a markup language used to create web pages. HTML files can contain text, images, scripts, and other media elements, and use markup tags to define the structure and behavior of these elements. By using HTML files, you can create interactive web pages with a variety of functions.
