HTML frame

Frames are an outdated feature of HTML and are no longer recommended for use in modern web development. Instead, it is recommended to use more modern techniques such as CSS grid, flexbox, or other layout tools to create responsive and flexible web layouts.

However, if you are interested in learning how frames used to work in HTML, here is an example of how to create a basic HTML page with frames:

<!DOCTYPE html>
<html>
<head>
	<title>My Frameset Page</title>
</head>
<frameset cols="25%, 75%">
	<frame src="menu.html">
	<frame src="content.html">
</frameset>
<body>
	<p>This is a fallback text for browsers that don't support frames.</p>
</body>
</html>

In this example, we use the <frameset> element to define a set of frames on the web page. The cols attribute specifies the width of the two frames in percentages, and the <frame> elements specify the content to be displayed in each frame.

Note that the src attribute of each <frame> element specifies the URL of the HTML document to be displayed in the frame.

Frames were once used to create complex web layouts, but their use is no longer recommended due to accessibility, SEO, and navigation issues. Instead, modern web development techniques such as CSS grid and flexbox can be used to create flexible and responsive layouts that are easier to maintain and more accessible to users.

HTML frameset and frame tags: The <frameset> tag was used to define the structure of frames, and <frame> tags were used to specify the content of each frame.
```
<frameset cols="25%, 75%">
    <frame src="frame1.html" name="frame1">
    <frame src="frame2.html" name="frame2">
</frameset>
```
HTML iframe for embedding content: While <frame> is deprecated, the <iframe> element is used to embed content from another source within a document.
```
<iframe src="embedded.html" width="600" height="400"></iframe>
```
HTML frame attributes: <frame> had attributes like src, name, noresize, and others to control the appearance and behavior of the frame.
```
<frame src="content.html" name="mainFrame" noresize>
```

Nested frames in HTML: Frames could be nested within other frames to create more complex layouts.

<frameset cols="50%, 50%">
    <frame src="frame1.html">
    <frameset rows="50%, 50%">
        <frame src="frame2.html">
        <frame src="frame3.html">
    </frameset>
</frameset>

HTML frame scrolling options: <frame> had a scrolling attribute to control whether scrollbars appear within the frame.
```
<frame src="scrollable-content.html" scrolling="auto">
```
HTML frame border styling: <frame> had a border attribute to control the border appearance.
```
<frame src="framed-content.html" border="1">
```
