I’m using GetBootstrap to check about compatibility and I get to choose the Bootstrap version in the top right that I’m using.
Where can I check in Blocsapp the version of Bootstrap that is supported so I don’t use features it doesn’t support?
Good to see you’re back giving Blocs another try. 
Use this to know the releases of Bootstrap:
https://github.com/twbs/bootstrap/releases
Use this to know how Blocs app compares:
https://blocsapp.com/release-notes/
You will have to search the second Blocs link for “bootstrap”, but doing so you will find that
Blocs 6.3.0 released Nov 17th 2025 was “Updated to Bootstrap Framework to v5.3.8”. Or you can Preview / Export and look through the page source at the CSS / JS for Bootstrap via Dev Tools.

I do not think I have ever checked the version of bootstrap for the features ! I just update Blocs when @norm updates it. I just concentrate on designing and building and not worry about these things. I have never come up against anything as yet, but I guess users going deep in depth will do.
I think Bootstrap is way ahead of features that I will ever need anyway for now.
Good luck!
Thanks, I had taken a look at that but didn’t do a ‘Find’ on it for ‘Bootstrap’. Thanks for showing me how to find it ‘in-app’ too.
