<noscript>
The content that appears when there is no JavaScript.
On a site made of little HTML pages, <noscript> is out of a job — and that is the herbarium's best joke. It only reveals its content when script is switched off or unavailable; inside <head> it accepts only link, style and meta.
Worth remembering that "no JavaScript" is almost never a choice by the person browsing. It is a tunnel, a corporate network, an over-eager blocker, a file that never arrived.

<p>Without JavaScript, everything here stays where it is.</p>
