JavaScript checkerboard

Hello,
I have a web programming project to submit.
There's a question where I'm stuck: Complete the style for the style tag of the document to define a black square and a white square, and use this style for the squares of the checkerboard.
Note: an HTML tag can have multiple CSS classes!
Tip: the sum of the coordinates of the squares modulo 2 (the remainder of the division by 2) tells you whether it's a white square or a black square.
How can we do this? Does anyone have a clue??
Thanks!

Configuration: Windows / Chrome 98.0.4758.102

    Hello
    You should already have the HTML and JavaScript code you started writing

    "Complete the style of the style tag of the document
    so it's a matter of CSS and not JavaScript.

    Tip: there is an even or odd selector

    Otherwise:
    "How can we do this? Does anyone have a lead??"
    Tip: the sum of the coordinates of the squares modulo 2 (the remainder of the division by 2) indicates whether it's a white square or a black square.

    Or simply check if a value is even, its result from division by two is the same for its integer value; for an odd number it is not:

    3/2 = 1.5
    2/2 =1

    IF Math.int(result)==result) => then even number
    => ELSE odd number

    even better with modulo which allows obtaining the modulo of a number
