Frames, a once-popular feature in web design, can divide a web page into several independent sections, each capable of showing a separate HTML document. However, their use has waned with the advent of more sophisticated techniques. The HTML5 specification even deprecates frames, favoring more modern, accessible, and user-friendly options like CSS layout modes. Nonetheless, it's worth understanding when the use of frames might be appropriate or necessary.
1. Legacy Code Maintenance
If you find yourself working on older websites, you may encounter frames. Understanding how they function is crucial for maintaining and updating such websites. Although it would be beneficial to eventually move away from frames for these sites, in the short term, the ability to work with frames can be handy.
2. Specific Design Requirement
There may be specific design requirements or limitations that make the use of frames necessary. For instance, you may need a section of your page to remain static while others scroll. While it's recommended to use CSS to create a fixed or sticky position for such requirements, in a pinch, or with older code, frames could provide a solution.

3. Internal Tools or Applications
Frames might still be used in some internal tools or applications where usability and accessibility aren't as crucial, or where the users are limited and understand how to interact with frames. An example might be a company's intranet applications or specific software tools.
4. Teaching or Demonstrating Historical Web Design
If you are teaching or demonstrating web design's historical aspects, using frames can show how web design has evolved over the years. It can provide a sense of where we started and how far we've come in terms of design, usability, and accessibility.
Conclusion
While the use of frames in modern web development is highly discouraged due to their impact on usability, accessibility, and SEO, there are scenarios where understanding and using them might be necessary or useful, particularly when dealing with legacy code or specific design requirements.
Modern techniques like CSS layout modes, AJAX, and server-side scripting have largely replaced frames, offering more versatility and better adherence to current web standards. These modern techniques can be practiced and perfected using tools like an online HTML compiler, which allows you to write, test, and tweak your HTML, CSS, and JavaScript code on-the-go, without needing any specific setup.
The online compiler for html can also come in handy if you're dealing with frames in legacy systems. You can experiment with the frames, understand their behavior, and work towards replacing them with more modern techniques.
So, unless absolutely necessary, it's always best to opt for these modern alternatives. Remember, the ultimate goal of web development is to create a user-friendly and accessible web experience, and modern design techniques, aided by resources like an online HTML compiler, are better suited to achieve this.
