What are Frame Tags?

Published in HTML Frames 3 mins read

Frame tags, in the context of HTML, were used to divide a web browser's window into multiple independent sections, each capable of displaying a separate HTML document. These sections are called frames, and a collection of frames is known as a frameset.

While frame tags offered a way to structure web pages, they are now considered deprecated in HTML5. Their usage is strongly discouraged in modern web development.

Key Features and Usage (Historically)

Here's a breakdown of how frame tags worked:

  • Division of the Browser Window: The primary purpose was to split the browser window into distinct, scrollable regions.
  • Independent HTML Documents: Each frame could load and display a different HTML document. This allowed for creating layouts with persistent navigation elements or dynamic content areas.
  • Frameset Definition: The <frameset> tag defined the structure of the frames – specifying the number of rows and columns, and their relative sizes.
  • Frame Definition: The <frame> tag defined each individual frame within the frameset, specifying the source URL (the HTML document to be displayed).

Example (Deprecated):

<frameset rows="25%,75%">
  <frame src="top_frame.html" name="topFrame">
  <frameset cols="20%,80%">
    <frame src="left_frame.html" name="leftFrame">
    <frame src="main_frame.html" name="mainFrame">
  </frameset>
</frameset>

This example would create a layout with:

  1. A top frame occupying 25% of the browser window's height.
  2. The remaining 75% of the height split into two columns: a left frame taking up 20% of the width and a main frame taking up 80%.

Why Frame Tags are Deprecated

The reasons for deprecating frame tags include:

  • Accessibility Issues: Frames can create difficulties for users with disabilities, particularly those using screen readers.
  • SEO Problems: Search engines can have trouble indexing content within frames.
  • Usability Concerns: Frame-based navigation can be confusing for users, as the URL may not reflect the content they are viewing.
  • Maintenance Complexity: Managing and updating websites built with frames can be more challenging.

Modern Alternatives

Modern web development offers more flexible and accessible alternatives to frame tags, such as:

  • Iframes: <iframe> tags allow embedding one HTML document within another, and are generally used for specific embedding purposes, like videos or maps, and are still supported. However, they should be used judiciously.
  • CSS Layout Techniques (Flexbox, Grid): CSS provides powerful layout tools (Flexbox and Grid) for creating complex and responsive layouts without the drawbacks of frames.
  • Server-Side Includes (SSI) or Template Engines: These technologies enable the reuse of common page elements (like headers and footers) across multiple pages, simplifying maintenance and ensuring consistency.
  • Web Components: Create reusable custom HTML elements that encapsulate functionality and styling.

In conclusion, frame tags provided a historical method for dividing browser windows, but they are outdated and should be avoided in favor of modern web development techniques that offer better accessibility, SEO, and usability.
