How to create HTML file (document)

First of all, you need an editor for coding. We recommend Sublime Text that works in any platform (Windows, Linux, Mac OS X).
When you are finished with the installation of Sublime Text on your PC, then open the program and copy some of the examples code that we have given below.
Further, in the top left corner click "File" and then on "Save as ..." option.
In "File name", type the name of the file that you want, and in the "Save as type" select extension Hyper Text Markup Language - html and and click "Save".
When done, open the document using your browser.


The default character encoding in HTML5 is UTF-8.
<meta charset="UTF-8">
