@danalvrz I went through all the code of exercise. I found some issue in hero block

1. Title align not working if there is no image in hero block edit mode
2. Same for subtitle
3. object_browser not working if we remove the selected image in hero block.
4. Another currently there is no initial width but we should have for hero block. see the screenshot for reference

Sorry, I won't have time to give this a thorough review before the training tomorrow

I would strongly suggest that you perform the following checks to make sure you don't have any glaring errors or warnings.

• https://training.plone.org/contributing/setup-build.html#livehtml
• https://training.plone.org/contributing/setup-build.html#id1
• and optionally https://training.plone.org/contributing/setup-build.html#overriding-configuration-options if you find that some checks are too noisy

Currently following the training at Plone conf. At this point I am wondering what the behaviours are that the VLT add-on adds. So a list would be nice.
Or a link to the backend add-on repo, as new behaviours may be added in the future.

I agree with @mauritsvanrees - It is extremely difficult to get the origin of the new behaviours explicitly from the description. I can guess them after watching a demo the same day, but this is not sustainable.

@danalvrz would you please address the feedback in this PR, or close it as "won't fix"? I'm preparing to archive trainings from 2025 to make space for 2026. Thank you!

@stevepiercy sorry for the delay here! Over the next few days I will address the comments and once more update the training to include changes in VLT 8 so it's in sync for 2026.
