将div划分为方块

Question

我有一个覆盖整个屏幕的div现在我想在这个div中动态生成方形Div，就像数学笔记本一样，为每个方块提供替代颜色

I can't give you too much because I don't know what you've tried and what specific problems you've encountered, but this'd be the basic idea:

for(var i = 0; i < 1000; i++) {
    var block = $('<div class="block" />');
    block.addClass('block-' + ((i%2)+1));

    $('body').append(block);
}

Have your .block div's float left, and set to the size you want them to be, and they'll automatically wrap to the next row. They'll also have either the class .block-1 or .block-2 , which you can use to set the alternating colors.

Of course, if a background image, as has been suggested in comments, would meet your needs, than that would perform heaps better :)
