The htm file extension is associated with Hypertext Markup Language. The HTML language provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. Its the main language for writing web pages.
The htm files are sometimes used on DOS-based computers, which can not understand extension with more than 3 characters. But the .htm files are the same as files with the HTML file extension.
The *.htm files are web pages coded in the HTML language. The .htm web page can be displayed in any Web browser. The .htm file formats texts, tables, images, and other content that will be displayed on the page. Most pages within static websites have the .html extension.
The HTML source code is parsed by the web browser and is usually not visible to the user. But users usually have the option to "view source file" in their web browser with which they can read the source code. Because the .html files are saved in a standard text format, they can be opened and edit with any text editor.
Since 1996, the HTML specifications have been maintained, with input from commercial software vendors, by the World Wide Web Consortium (W3C). However, in 2000, HTML also became an international standard (ISO/IEC 15445:2000). The last HTML specification published by the W3C is the HTML 4.01 Recommendation, published in late 1999. Its issues and errors were last acknowledged by errata published in 2001.
The used Mime-type is:
text/html
