Template documentationThis template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
To change this template's initial visibility, the |state= parameter may be used:
{{Blackbody radiation laws|state=collapsed}}will show the template collapsed, i.e. hidden apart from its title bar.{{Blackbody radiation laws|state=expanded}}will show the template expanded, i.e. fully visible.
Usage
Use this template at the bottom of appropriate Wikipedia articles. See WP:LAYOUT for the proper order of page elements.
