Custom CSS, Global JS and embeds

Most sites need no code. When you do, there are three places for it.

Page CSS

Each page has its own stylesheet, edited in a code editor in the builder's Settings. Use the element's Classes field to attach your own class names, then style them here.

Website stylesheet

Rules every page needs belong in the website stylesheet (see Style presets and site CSS).

Global JS

Each website (CMS Project) has one Global JS script that runs once on every published page. It never runs inside the builder, so a script cannot break your editing.

  • Edit it in the builder under Settings › Global JS, with an expanded editor for longer scripts.
  • It is injected the first time a page of that website is shown and is not run again on later in-site navigations.
  • It suits a storefront runtime, analytics hooks or shared helpers, instead of pasting the same script into many embeds.
  • The page's Vue is available, so a global script can define small components with template: strings.

Page scripts and events

For behaviour tied to one element, use events instead of code: a click, change, submit or scroll can run a short script, call an API, navigate, or show a message (see Variables, resources and events).

HTML embeds

The HTML Embed element holds third-party markup such as a booking widget. It renders on the published page only.

Warning

Scripts run with the visitor's session on your domain. Only paste code from sources you trust.
