Are you aware? HTML is used to build the majority of web pages on the World Wide Web (WWW).

HTML is a markup language that plays a vital role in the formatting of various programming languages such as PHP, ASP.net, JAVA, and others.

The browser reads an HTML web page and displays the results of back end programming.

What is HTML file?

HTML stands for Hyper Text Markup Language, and it is used to create web pages and web applications.

Let’s examine what Web page and Hypertext Markup Language mean.

Hypertext is just “Text within Text,” as the name suggests. A text that contains links is a hypertext.

A hypertext link is one that when you click on it opens a new webpage for you. Two or more web pages (HTML documents) can be linked together via hypertext.

A markup language is a type of computer language that is used to apply formatting and layout rules to text documents.

Text is made more interactive and dynamic using markup language. It can convert text into graphics, tables, links, and other formats.

What is an HTM file?

An HTM file is an HTML webpage that can be viewed using web browsers such as Google Chrome, Microsoft Edge, and Mozilla Firefox.

It might include markup language, which describes the components and design of a webpage, as well as hyperlinks.

Since HTM files are saved in plain text format, they can also be opened with a simple text editor.

However, because HTM files have useful coding features, a source code editor should be used to modify them.

Difference between .html vs .htm (HTML vs HTM)

HTML is the current operating system extension for HTML web pages and files.

Furthermore, the.html extension was introduced for security reasons, as the three-letter extension.htm contained more security threats.

HTM is an older version of the HTML filename extension.

This extension was used in the past because operating systems were not powerful enough to handle four-letter extensions.

Because the.htm extension was less secure than the.html extension, the.html extension was created.
