Should You Put `` Tags After the Closing `` Tag?

Should You Place the <script> Tag After the </body> Tag?

Placing the <script> tag after the closing </body> tag has been a subject of debate in web development circles. Here, we delve into the potential implications of this unconventional practice.

Technical Constraints and Implications

While placing the <script> tag after the </body> may not be considered an error, it might hinder validation efforts. According to web standards, scripts should reside within either the <head> or the <body> tags.

Performance Considerations

Although the positioning of the <script> tag generally does not impact overall performance, an exception exists when relying on DOM manipulation techniques. Placing the <script> at the very end of the document can result in potential issues with Internet Explorer versions prior to the full loading of the <body> element.

Best Practices

Despite the lack of significant performance implications, it is generally recommended to place the <script> tag just before the </body> tag. This approach ensures code validation and avoids potential complications with browser compatibility.

Example Code

Here's an example of the recommended approach:

&lt;!-- ... HTML code ... --&gt;
&lt;body&gt;
  &lt;!-- ... Page content ... --&gt;
  &lt;script type=&quot;text/javascript&quot; src=&quot;theJs.js&quot;&gt;&lt;/script&gt;
&lt;/body&gt;
&lt;!-- ... HTML code ... --&gt;

Copy after login

Conclusion

While placing the <script> tag after the </body> may not be technically incorrect, it is generally advisable to adhere to best practices and include it before the closing </body> tag. This approach helps ensure web standards compliance and minimizes compatibility issues, particularly in older browser versions.
