Script Tag Placement: Inside or Outside the Tag? In HTML, it is a common question whether it is appropriate to place the tag outside of the <body> tag.</p> <h3>Validation and Browser Compatibility</h3> <p>Placing the <script> tag outside of the <body> or <head> tags will cause the code to fail validation. Additionally, older versions of Internet Explorer may encounter issues if DOM manipulations are performed before the <body> element has fully loaded.</p> <h3>Performance Implications</h3> <p>In terms of performance, there is generally no significant difference between placing the <script> tag just before the closing </body> tag or inside the <head>. However, if the script is relatively large, placing it inside the <head> can potentially improve loading speed by sending it to the browser sooner.</p> <h3>Best Practice Recommendation</h3> <p>For best practices and compatibility, it is generally recommended to place the <script> tag just before the closing </body> tag. This ensures that it will load at the appropriate time and avoid any validation issues.</p>
