Let’s take one interactive feature apart so the markup and behavior make sense separately.
What You Need to Know
The experimental geolocation element is intended to present location permission through browser UI. It is not a broadly supported HTML control, so offer a separate way to enter a location.
Try the Example
Take a look at the example. We’ll explain the important lines right below it.
<p>Share your location only if you want to.</p>
<geolocation>
<button type="button">Use my location</button>
</geolocation>
<p>In browsers without support, use a separate location form.</p>Let’s Read the Code
- <geolocation>: Geolocation is an experimental browser-managed permission and location control; do not rely on broad support.
- <button>: The button offers an action; its type or command determines what happens.
- type: Type changes what sort of control or resource the browser uses.
Read the named elements and attributes together. They explain how the browser connects this feature to the rest of the page.
What Happens in the Browser?
This feature has limited or experimental browser support. Check your target browsers before using it for something essential.
Do not depend on one browser. Some advanced HTML features are still being adopted. Check support before you build essential navigation or forms with them, and keep a simpler version that people can use if the advanced feature is unavailable.
Your Turn
Run this on a local development server if it loads modules or resources. Change the visible text or trigger and check what still works with scripts disabled.
Common Beginner Mistakes
- Assuming new HTML syntax works in every browser without testing.
- This feature has limited or experimental browser support. Keep a standard HTML fallback, and check compatibility before using it in a public site.
Key Takeaways
- The experimental geolocation element is intended to present location permission through browser UI.
- <geolocation>: Geolocation is an experimental browser-managed permission and location control; do not rely on broad support.
- This lesson explains an emerging feature; it is not a promise that the feature works in every browser. Keep a usable fallback.
