Script-supporting element - MDN Web Docs Glossary: Definitions of Web-related terms 编辑

In an HTML document, script-supporting elements are those elements that don't directly contribute to the appearance or layout of the page; instead, they're either scripts or contain information that's only used by scripts. These elements may be important, but do not affect the displayed page unless the page's scripts explicitly cause them to do so.

There are only two script-supporting elements: <script> and <template>.
