Choose Bootstrap 3 or 4
Beaver Builder Theme is built on the Bootstrap framework, and Bootstrap is transitioning from Version 3 to Version 4. Here's a good technical summary of the changes in Bootstrap 4. Note in particular the change in browser support.
The Beaver Builder Theme Version 1.7.9 upgraded to Bootstrap Version 4.6.0.
In Customize > General > Layout, there's a Framework field with settings to help in the eventual transition to Bootstrap 4 or to choose which version of Bootstrap you want if you're having any issues. You can choose from the following settings:
- Minimal Bootstrap 3
The default setting, and the one to keep if you're not sure. It loads a minimal version of Bootstrap 3 with the functionality required to ensure that the theme works as it does now. - Minimal Bootstrap 4
Loads a minimal version of Bootstrap 4. - Full Bootstrap 3
Loads the full version of Bootstrap 3. - Full Bootstrap 4
Loads the full version of Bootstrap 4.
The Minimal Bootstrap is a lightweight build that only contains the CSS needed for the grid system and basic styling. This includes:
- Grid
- Print Styles
- Typography
- Code
- Tables
- Forms
- Navs
- Navbar
Full Bootstrap includes all CSS and JavaScript with the exception of Popper.js. To use popper.js with the BB Theme you will need to enqueue the script.
If you have a new site and want to use Bootstrap 4 features and don't mind the loss of support for older systems, you can try choosing Bootstrap 4. If you have existing customizations using Bootstrap 3 or Bootstrap 4 and need to ensure your layouts are not broken, choose the appropriate version.
