See: [Using the JS API](https://meta.discourse.org/t/using-the-pluginapi-in-site-customizations/41281) Here’s an example function: \<script type="text/discourse-plugin" version="0.8"\> api.onPageChange(() =\>{ randBackground(); }); function randBackground() { $('body').css('background-color', '#'+(Math.random()\*0xFFFFFF\<\<0).toString(16)); } \</script\> Update: If you are looking to apply similar changes to post bodies, see [post #26 below](https://meta.discourse.org/t/how-do-you-force-a-script-to-refire-on-every-page-load-in-discourse/74856/26).
