Q1. Describe how you would implement a dynamically updating news feed using Bootstrap.
- Use the Bootstrap Carousel component
- Utilize AJAX for real-time updates
- Implement a custom JavaScript solution
- Employ Bootstrap's Popover component
To implement a dynamically updating news feed in Bootstrap, using AJAX for real-time updates is the most suitable approach. This allows fetching and displaying new content without requiring a full page reload. The Carousel component is commonly used for slideshow-like features, but for dynamic updates, AJAX is more appropriate.
What event is triggered when a Bootstrap modal is fully shown?
- shown.bs.modal
- modal('show')

Minifying Bootstrap CSS and JavaScript files reduces their size, leading to faster loading times for web pages and improved overall performance. Additionally, it helps in optimizing network usage and improving user experience.
In successful Bootstrap implementations, what is a common strategy for handling cross-browser compatibility?
- Using browser-specific code
- Ignoring cross-browser compatibility
- Relying solely on CSS

Q1: In a Bootstrap form, how do you ensure that data submission is handled through AJAX without a page reload?
- Use the data-ajax attribute on the form element
- Implement a custom JavaScript function for form submission
- Set the form's action attribute to the AJAX endpoint
- Utilize the Bootstrap ajax-form class
When working with Bootstrap forms, AJAX handling is typically implemented by creating a custom JavaScript function for form submission. This allows you to intercept the form submission event and perform an AJAX request instead of a traditional page reload.
To create a bouncing animation in Bootstrap, use the class '___'.
- bounce
- animate-bounce
- bounce-animation

In Bootstrap, the correct class for creating a bouncing animation is bounce. This class adds a simple bouncing effect to the element. It's essential to use the appropriate class for the desired animation effect.
To adjust the width of the container for large devices, modify the ___ variable in Bootstrap.
- container-lg-width
- large-container-width
- container-width-lg
- lg-container-size
When customizing the width of the container for large devices in Bootstrap, you should modify the container-lg-width variable. This variable allows you to control the width specifically for large devices, ensuring a responsive layout for different screen sizes.
Which CSS selector specificity is typically required to override Bootstrap's styles?
- Class specificity (e.g., .my-custom-class)
- Element specificity (e.g., div, p)
- ID specificity (e.g., #my-custom-id)
- Universal selector (e.g., *)
To override Bootstrap styles, you usually need higher specificity. Class specificity (e.g., .my-custom-class) or ID specificity (e.g., #my-custom-id) is often used to ensure that your styles take precedence over Bootstrap's.
