InContext
This approach loads your website via an iframe in the InContext view. For an alternative approach, have a look at the locize module or the locizify script in combination with the query parameter
?incontext=true.
The InContext view
Correct translations often need more context. The best context is where the content is shown: your website.
So we bring your Locize project closer to your website/application:

When integrated correctly, you can click any text element on your website shown in the iframe. Locize will use that information to find the matching key/value on the left.
If you need to navigate on your page, you can turn click interception on/off using the button next to your website URL.
Make sure to select the language you want to work on at the top.
