Explain the process of updating a Bootstrap project when a major version change occurs in an integrated third-party JS library.
- Manually adjust Bootstrap code to match the library's new version
- Update the library to match Bootstrap's version
- Use polyfills to bridge compatibility gaps
- Rollback Bootstrap to a compatible version
Checking the library's documentation and updating it to align with the new Bootstrap version is the recommended approach, avoiding manual adjustments and ensuring compatibility.

- Tooltips are triggered by click, while Popovers are triggered by hover
- Popovers are only used for images

Describe a scenario where using Sass nesting in Bootstrap would be more effective than traditional CSS.
- Nesting allows for more scoped styles, avoiding global scope pollution.
- Nesting helps in creating cleaner and more maintainable code when styling nested HTML structures.
- Nesting enhances selector specificity, ensuring targeted styling in complex layouts.
- Nesting can cause performance issues in large projects due to increased selector specificity.
In scenarios where you have deeply nested HTML structures, Sass nesting in Bootstrap proves effective by providing a more structured and maintainable way to write styles. Nesting avoids the need for repeating parent selectors and helps in creating a modular and organized stylesheet. This is particularly beneficial in large projects where traditional CSS may lead to global scope pollution and increased selector specificity issues.
In Bootstrap, which JavaScript method is used to programmatically open a modal?
- showModal()
- openModal()
