CSS object-position

🎯 한 줄 통찰 (One-line insight)

The CSS object-position property is used together with object-fit to specify how an <img> or <video> should be positioned with x/y coordinates within its container. [S1]

🧠 핵심 개념 (Core concepts)

• Purpose — object-position positions an <img> or <video> with x/y coordinates within its container, used together with object-fit. [S1]
• First value = x-axis, second value = y-axis. [S1]
• Value forms — strings (left, center, right) or numbers (px or %). [S1]
• Negative values are permitted. [S1]

🧩 추출된 패턴 (Extracted patterns)

• Reframe a cropped image — when object-fit: cover; crops an image, use object-position to choose which part of the image stays visible. [S1]
• x/y pair — supply two values: the first shifts horizontally, the second shifts vertically. [S1]
