what does grid-template-columns:repeat(2,1fr); do in CSS ?

The question is a conceptual multiple-choice question related to CSS (Cascading Style Sheets).

• Answer: A

• Explanation: The grid-template-columns: repeat(2, 1fr); CSS property is used to define the layout of columns in a grid container. The repeat(2, 1fr) function creates two columns, each taking up an equal fraction of the available space. The 1fr unit stands for "one fraction of the available space," meaning each column will have an equal share of the space within the grid container.

• Option Analysis:

  • A: Correct. This option correctly describes the behavior of repeat(2, 1fr), which creates two columns that equally divide the available space.
  • B: Incorrect. This option might suggest a different number of columns or a different distribution of space, which is not what repeat(2, 1fr) does.
  • C: Incorrect. This option could imply a fixed width or a different unit of measurement, which is not applicable here.
  • D: Incorrect. This option might suggest a different layout property or behavior unrelated to the repeat function or the fr unit.

In summary, grid-template-columns: repeat(2, 1fr); is used to create a grid layout with two equally spaced columns.
