– What are Frames?
Frames are a technique used in web design to divide a web page into multiple sections or frames. The purpose of frames is to allow multiple documents to be displayed within the same web page, with each document (or frame) having its own scrollbar. This allows the user to view multiple documents at the same time, instead of having to switch between them. In addition, frames can also be used to keep certain elements of a page visible while other elements are scrolled. For example, a navigation menu could remain visible while content is scrolled beneath it. Frames can also be used for layout purposes, allowing for more control over how different elements of the page are arranged. – Benefits of Using Frames
– Design Considerations for Frames
Frames are a web design feature that divides a web page into two or more sections, each of which can be independently scrolled. They are typically used to display multiple sections of related content on the same page, such as a navigation menu and the main content area. Frames can also be used to display an entirely different website within a frame. Designers should consider several factors when using frames in their web designs, including browser compatibility, search engine optimization, and user experience. Browser compatibility is important since some browsers may not be able to properly render frames. Search engine optimization is also important since search engines may not be able to index framed content properly. Finally, user experience should always be taken into account when designing with frames, as users may find it difficult to navigate if the frames are not properly implemented.
– How to Create Frames in HTML
Web browsers use frames to display content, including website pages, in a different format. Frames are not recommended for most websites due to their limited functionality and SEO issues. Most websites should use the standard method of adding content to a page (which is to add HTML markup directly to the document, or tags directly into the page) for their primary content. Frames are only useful when used in specific situations, such as providing support for other types of content (e. g., images and video) that would not otherwise work in a standard website. Frames can also provide additional functionality (such as a form you can submit from an external website). Frames are also useful for creating customized pages to share with others, provided each frame has unique content.
HTML frames are a way to divide the browser window into multiple sections, where each section can load a separate HTML document. Frames are defined by the <frameset> tag and the <frame> tag. However, they’re considered outdated and not recommended for modern web design, primarily because they can cause accessibility issues, and they’re not responsive to different screen sizes. They are also not supported in HTML5.
Still, for historical and learning purposes, here’s how to use them:
- HTML Document Structure with Frames
Instead of the usual <body> tag, you would use <frameset> when working with frames.
<html>
<head>
<title>Frames Example</title>
</head>
<frameset> <!-- frames go here --> </frameset>
</html>- Define Rows or Columns
You can split the screen either vertically into rows using rows or horizontally into columns using cols.
For example, to split the screen into two horizontal sections:
<frameset rows="50%,50%">
<frame src="top.html"> <frame src="bottom.html">
</frameset>Or, for two vertical sections:
<frameset cols="50%,50%"> <frame src="left.html"> <frame src="right.html"> </frameset>You can also use specific pixel values or relative percentages.
- Nested Framesets
You can have nested framesets. Here’s an example that divides the screen into three sections:
- Left (50% of the screen)
- Top right (25% of the screen’s height)
- Bottom right (remaining 25% of the screen’s height)
<frameset cols="50%,50%"> <frame src="left.html"> <frameset rows="50%,50%"> <frame src="top_right.html"> <frame src="bottom_right.html"> </frameset> </frameset>- Attributes
The <frame> tag supports several attributes, such as:
src: Specifies the URL of the document to show in the frame.name: Names a frame so that you can target it using links.noresize: Prevents users from resizing the frame.scrolling: Determines if scroll bars are shown. Can be “yes”, “no”, or “auto”.
- Links and Target Attribute
To open a link in a specific frame, you can use the target attribute in the <a> tag:
<a href="somepage.html" target="frameName">Link Text</a>- noframes
<noframes> is used to specify content to be displayed to browsers that don’t support frames:
<frameset cols="50%,50%"> <frame src="left.html"> <frame src="right.html"> <noframes> <body> Your browser doesn't support frames. Please update to a newer version. </body> </noframes> </frameset>- Examples

Instead, if you want to achieve similar layouts, you can utilize CSS frameworks or grid/flexbox properties.
