This tutorial follows the latest HTML5 standard.
(HTML Editors) A simple text editor is all you need to learn HTML.
Web pages can be created and modified by using professional HTML editors.
However, for learning HTML we recommend a simple text editor like Notepad (PC) or TextEdit (Mac).
We believe in that using a simple text editor is a good way to learn HTML.
(HTML Editors) Follow the steps below to create your first web page with Notepad or TextEdit.
Step 1: Open Notepad (PC)
Windows 8 or later:
Open the Start Screen (the window symbol at the bottom left on your screen). Type Notepad.
Windows 7 or earlier:
Open Start > Programs > Accessories > Notepad
(HTML Editors) Step 2: Write Some HTML.
Write or copy the following HTML code into Notepad:
<!DOCTYPE html>
<html>
<body>

<h1>My First Heading</h1>

<p>My first paragraph.</p>

</body>
</html>
(HTML Editors) Step 3: Save the HTML Page. Save the file on your computer. Select File > Save as in the Notepad menu.
Name the file "index.htm" and set the encoding to UTF-8 (which is the preferred encoding for HTML files).
(HTML Editors) Tip:
You can use either .htm or .html as file extension. There is no difference, it is up to you.
(HTML Editors) Step 4: View the HTML Page in Your Browser.
Open the saved HTML file in your favorite browser (double click on the file, or right-click - and choose "Open with").
