Q1. [CSS Positioning] Q1: Which value creates a sticky header that stays at top: 0 until scrolled
past?
A. position: static
B. position: sticky with top:0
C. position: fixed always
D. position: absolute

Correct Answer: B
Rationale (74 words): Verified correct is B for CSS Positioning. This concept is critical for CSS layout because it
determines how elements are sized, aligned, and rendered within their containing block and viewport. The incorrect
answers describe similar but distinct mechanisms that serve different purposes or have syntax errors. For example, one
distractor confuses main-axis with cross-axis alignment, another misstates default values. Mastering this distinction is
essential for implementing flexbox grids, responsive breakpoints, and Bootstrap utilities correctly.
