Fill both blanks to create a responsive BootstrapVueNext grid with two columns.

Bootsrap

<template>
  <b-row>
    <b-col cols="[1]">Column 1</b-col>
    <b-col cols="[2]">Column 2</b-col>
  </b-row>

💡 Hint

Common Mistakes

Using column sizes that don't add up to 12

Using string values without quotes

Using the same column size for both blanks but not 6

Using cols="6" for each column divides the row into two equal halves (6 + 6 = 12 columns total).

5fill in blank

hard

Fill all three blanks to create a BootstrapVueNext alert with variant 'success' and dismissible property.

Bootsrap

<template>
  <b-alert variant="[1]" :dismissible="[2]" @dismissed="[3]">
    Operation completed successfully.
  </b-alert>
</template>

<script setup>
function handleDismiss() {
  alert('Alert dismissed');
}
</script>

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using wrong variant like 'danger'

Setting dismissible to a string instead of boolean

Not connecting the dismissed event to the handler function

The alert variant should be "success" for a green alert. The dismissible prop is a boolean, so use true. The @dismissed event calls the handleDismiss function.

Practice

1. What is the main purpose of bootstrap-vue-next in a Vue 3 application?

easy

A. To replace Vue 3 with Bootstrap framework

B. To create backend APIs using Bootstrap

C. To convert Bootstrap CSS into JavaScript code

D. To easily use Bootstrap styles and components inside Vue 3 apps

Solution

1. Step 1: Understand BootstrapVue Next role

   BootstrapVue Next is a library that integrates Bootstrap styles and components into Vue 3 apps.

2. Step 2: Eliminate incorrect options

   Options A, C, and D describe unrelated or incorrect uses of BootstrapVue Next.

3. Final Answer:

   To easily use Bootstrap styles and components inside Vue 3 apps -> Option D

4. Quick Check:

   BootstrapVue Next = Bootstrap + Vue 3 integration [OK]

Hint: Remember: BootstrapVue Next adds Bootstrap to Vue 3 apps [OK]

Common Mistakes:

• Thinking it replaces Vue 3
• Confusing CSS with JavaScript conversion
• Assuming it builds backend APIs

2. Which of the following is the correct way to import Bootstrap CSS in a Vue 3 project using bootstrap-vue-next?

easy

A. import 'bootstrap-vue-next/dist/css/bootstrap.css';

B. import 'bootstrap/dist/css/bootstrap.min.css';

C. import 'vue/dist/css/bootstrap.css';

D. import 'bootstrap-vue-next/css/bootstrap.min.js';

Solution

1. Step 1: Identify Bootstrap CSS import

   The official Bootstrap CSS file is imported from 'bootstrap/dist/css/bootstrap.min.css'.

2. Step 2: Check other options

   import 'bootstrap-vue-next/dist/css/bootstrap.css'; is incorrect because bootstrap-vue-next does not provide CSS files directly. import 'vue/dist/css/bootstrap.css'; is wrong as Vue does not have Bootstrap CSS. import 'bootstrap-vue-next/css/bootstrap.min.js'; imports a JS file, not CSS.

3. Final Answer:

   import 'bootstrap/dist/css/bootstrap.min.css'; -> Option B

4. Quick Check:

   Bootstrap CSS import path = 'bootstrap/dist/css/bootstrap.min.css' [OK]

Hint: Bootstrap CSS always comes from 'bootstrap/dist/css' folder [OK]

Common Mistakes:

• Importing JS files instead of CSS
• Using bootstrap-vue-next for CSS import
• Confusing Vue package with Bootstrap CSS

3. Given the following Vue 3 component using bootstrap-vue-next:

<template>
  <b-button variant="primary">Click Me</b-button>
</template>

<script setup>
import { BButton } from 'bootstrap-vue-next';
</script>

What will be the visual result when rendered in the browser?

medium

A. A blue Bootstrap styled button labeled 'Click Me'

B. A plain HTML button with no styling

C. An error because BButton is not registered

D. A red button labeled 'Click Me'

Solution

1. Step 1: Understand component usage

   The <b-button> component from bootstrap-vue-next renders a Bootstrap styled button. The variant 'primary' applies the blue color.

2. Step 2: Check registration and rendering

   Since BButton is imported and used correctly, the button will render with Bootstrap's primary style (blue).

3. Final Answer:

   A blue Bootstrap styled button labeled 'Click Me' -> Option A

4. Quick Check:

   Bootstrap button variant 'primary' = blue button [OK]

Hint: Bootstrap 'primary' variant means blue button [OK]

Common Mistakes:

• Assuming no styling without global registration
• Confusing variant colors
• Thinking import alone causes error

4. Consider this Vue 3 setup using bootstrap-vue-next:

<script setup>
import { BAlert } from 'bootstrap-vue-next';
</script>

<template>
  <b-alert show>Warning message</b-alert>
</template>

The alert does not appear when running the app. What is the likely cause?

medium

A. BAlert component is imported but not registered globally or locally

B. The show attribute is invalid for BAlert

C. Bootstrap CSS is missing from the project

D. Vue 3 does not support bootstrap-vue-next components

Solution

1. Step 1: Check component import and usage

   BAlert is imported and used correctly with the show attribute, which is valid to display the alert.

2. Step 2: Consider missing Bootstrap CSS

   If Bootstrap CSS is not imported, components render without styles and may not appear as expected.

3. Final Answer:

   Bootstrap CSS is missing from the project -> Option C

4. Quick Check:

   Missing Bootstrap CSS = no visible styles [OK]

Hint: Always import Bootstrap CSS to see styled components [OK]

Common Mistakes:

• Assuming import auto-registers components globally
• Thinking 'show' attribute is invalid
• Believing Vue 3 is incompatible with bootstrap-vue-next

5. You want to create a responsive grid layout in Vue 3 using bootstrap-vue-next with two columns on large screens and one column on small screens. Which template code correctly achieves this?

hard

A. <template>
<b-row>
<b-col cols=12 lg=6>Column 1</b-col>
<b-col cols=12 lg=6>Column 2</b-col>
</b-row>
</template>

B. <template>
<b-row>
<b-col lg=12 cols=6>Column 1</b-col>
<b-col lg=12 cols=6>Column 2</b-col>
</b-row>
</template>

C. <template>
<b-row>
<b-col cols=6>Column 1</b-col>
<b-col cols=6>Column 2</b-col>
</b-row>
</template>

D. <template>
<b-row>
<b-col cols=12>Column 1</b-col>
<b-col cols=12>Column 2</b-col>
</b-row>
</template>

Solution

1. Step 1: Understand Bootstrap grid props

   Using cols=12 means full width on small screens, and lg=6 means half width on large screens.

2. Step 2: Check each option's column sizing

   <template> <b-row> <b-col cols=12 lg=6>Column 1</b-col> <b-col cols=12 lg=6>Column 2</b-col> </b-row> </template> correctly sets columns to full width on small and half width on large screens. Other options have incorrect prop values or missing responsive behavior. <template> <b-row> <b-col cols=12>Column 1</b-col> <b-col cols=12>Column 2</b-col> </b-row> </template> always uses full width.

3. Final Answer:

   <template> <b-row> <b-col cols=12 lg=6>Column 1</b-col> <b-col cols=12 lg=6>Column 2</b-col> </b-row> </template> -> Option A

4. Quick Check:

   cols=12 small + lg=6 large = responsive 1 or 2 columns [OK]

Hint: Use cols=12 for small, lg=6 for large screens in b-col [OK]

Common Mistakes:

• Mixing cols and lg values incorrectly
• Forgetting responsive props for different screen sizes
• Using only cols without breakpoints
