Despite my best efforts, I wasn’t able to complete the migration from Bootstrap 3 to Bootstrap 5. Here’s what went wrong and what I learned from the process.
The Gap Between Bootstrap 3 and Bootstrap 5
The differences between Bootstrap 3 and Bootstrap 5 turned out to be much larger than I initially anticipated. It wasn’t just about adding new features; the way components are structured and used has changed significantly. Adapting to the new grid system and rewriting JavaScript components required careful attention to detail, making the migration process far more complex than expected.
Layout Issues
One of the biggest challenges was the layout. Even after updating all the grid classes and testing responsiveness, the layout in Bootstrap 5 didn’t align perfectly with the original one in Bootstrap 3. There were subtle differences in spacing, alignment, and overall design that proved difficult to resolve. Fixing these issues would have required more time and resources than I had available.
Too Many Details to Modify
There were countless details that needed to be addressed, including:
- Updating custom scripts that relied on jQuery.
- Adjusting styles for deprecated CSS classes.
- Testing and debugging every component to ensure functionality and visual consistency.
Each of these tasks was time-consuming on its own, but together, they became overwhelming and made it impossible to finish the migration within the planned timeline.
