Plain HTML
Install the snippet once
Section titled “Install the snippet once”Paste this once per page, in <head> or just before </body>:
<script async src="https://cdn.taggorcdn.com/s/<site-key>.js"></script>async runs the script as soon as it is fetched without blocking the parser; defer waits for the parse
and keeps order (MDN, script, https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/script, read 2026-11-09). The loader depends on no other script, so async is right for it.
Place the component
Section titled “Place the component”<contact-form heading="Get in touch"></contact-form>A prop is an attribute, and an attribute carries text: lists and objects need the element’s property, see Components in React, Vue and Angular.
Limits
Section titled “Limits”- A site with a Content-Security-Policy needs the
nonceand the CDN origin: Install the snippet. - The page keeps whatever you wrote inside the tag when the script cannot run: Fallback content.
Common problems
Section titled “Common problems”- Nothing appears. Open the browser console: a Content-Security-Policy violation names the directive to
allow, and a
taggorwarning names the domain list (Allowed domains). - The page jumps when the component appears. Reserve its size with
:not(:defined).
How we checked
Section titled “How we checked”The plain page runs in the compatibility matrix with the real loader, in Chromium, Firefox and WebKit and two mobile emulations, with the snippet in the head and at the end of the body.
