rectangle函数在网页布局中的模拟

function rectangle(width, height) { let rectangle = document.createElement(‘div’); rectangle.style.width = width + ‘px’; rectangle.style.height = height + ‘px’; rectangle.style.backgroundColor = ‘blue’; document.body.appendChild(rectangle); }

rectangle(200, 100); // 创建一个宽度为200px，高度为100px的蓝色矩形
