1. What does the CSS property object-fit: cover; do to an image inside a container?

easy

A. It fits the entire image inside the container without cropping.

B. It stretches the image to fill the container, possibly distorting it.

C. It fills the container completely, cropping parts if needed.

D. It repeats the image to fill the container.

Solution

1. Step 1: Understand object-fit: cover; behavior

   This property makes the image fill the container completely, cropping parts if the aspect ratio differs.

2. Step 2: Compare with other options

   Unlike contain which fits without cropping, cover crops to fill fully.

3. Final Answer:

   It fills the container completely, cropping parts if needed. -> Option C

4. Quick Check:

   Cover = fill and crop [OK]

Hint: Cover fills and crops; contain fits without cropping [OK]

B. object-fit: fill;

C. object-fit: crop;

D. object-fit: contain;

Solution

1. Step 1: Identify the property for fitting without cropping

   Cover + center = fill fully, crop center visible [OK]

Hint: Cover fills and crops; center keeps main part visible [OK]

Common Mistakes:

• Using contain leaves empty space
• Using fill distorts video
• Ignoring object-position for cropping focus
