Possible disadvantages

  • Dependency on jQuery
    Older versions of Bootstrap heavily rely on jQuery, which can be a disadvantage for projects that aim to minimize dependencies.
  • Specific Structure
    Bootstrap works best when you adhere to its predefined structure and classes, which can limit flexibility for more complex or unique designs.
  • Customization Challenges
    Deep customization can be difficult and time-consuming, especially if you need to override many default styles and behaviors.
  • Performance Issues
    Using a large number of Bootstrap components can lead to performance issues, particularly on lower-end devices.
