Map embed

The map at projectcert.org/map/ is distributed for embedding via <iframe>. The embedded view includes an attribution line linking to projectcert.org and to the seed paper. Distribution terms are governed by CC BY 4.0; attribution must remain visible.

Fixed-height snippet

Renders at full container width with a fixed pixel height. Suitable for desktop-first layouts. 

<iframe
  src="https://projectcert.org/embed/map/"
  title="EL teacher certification — projectcert"
  width="100%"
  height="820"
  loading="lazy"
  style="border: 0; max-width: 100%;"
  referrerpolicy="no-referrer-when-downgrade"
></iframe>

Responsive snippet (recommended)

Maintains a roughly 10:9 aspect ratio so the map remains legible on small viewports. 

<div style="position: relative; width: 100%; padding-bottom: 92%;">
  <iframe
    src="https://projectcert.org/embed/map/"
    title="EL teacher certification — projectcert"
    loading="lazy"
    style="position: absolute; inset: 0; width: 100%; height: 100%; border: 0;"
    referrerpolicy="no-referrer-when-downgrade"
  ></iframe>
</div>

Layer-locked variants

Appending ?layer=<name> sets the initial encoded variable. The layer selector inside the embed remains active.
