Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the Bootstrap grid with col-lg-6 and col-md-12 classes
Bootstrap's grid system with col-lg-6 and col-md-12 classes provides a responsive two-column to single-column transition. Column widgets are not for responsive layout.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a single-column layout with media queries
Why it's wrong here
A single-column layout with media queries fails because the developer needs a two-column layout on desktop, yet this approach never creates a second column—it only adjusts the single column’s width or spacing. It is tempting because media queries are the standard tool for responsive breakpoints, and this method would be correct if the requirement were simply to stack content vertically across all screen sizes.
- ✗
Use the Column widget in UI Builder
Why it's wrong here
Incorrect: Column widget is not for responsive grid layout.
- ✗
Use fixed-width tables
Why it's wrong here
Incorrect: Fixed-width is not responsive.
- ✓
Use the Bootstrap grid with col-lg-6 and col-md-12 classes
Why this is correct
Correct: This will stack columns on small screens.
