The complete list of what custom code on an Advanced page may use. Anything else is removed when you save; the editor shows what before you publish. For a walkthrough, see Make your page with HTML, step by step.

CSS
Everything that styles a page, kept as written, including custom properties (--color), nesting, @media, @supports, @container, @layer, @scope, @keyframes, @font-face, @property, @counter-style and @page. @import of a stylesheet becomes a <link>.
Removed, one declaration at a time: expression(), behavior, -moz-binding, image-set(), element(), paint() and any url() that is not an allowed address.
Built in
- Pages start with no margin around the body, like a site builder. Your own CSS overrides that.
- Countdown:
<time class="lk-timer" datetime="2030-01-01T00:00:00Z" title="Text when it ends"></time>. - Clicks on web links are counted in your stats.
