如何在砖石js中将项目居中？

.container {
  display: flex;
  justify-content: center;
  align-items: center;
}

.container {
  position: relative;
}

.project {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

const container = document.querySelector('.container');
const project = document.querySelector('.project');

const containerWidth = container.offsetWidth;
const containerHeight = container.offsetHeight;
const projectWidth = project.offsetWidth;
const projectHeight = project.offsetHeight;

const leftOffset = (containerWidth - projectWidth) / 2;
const topOffset = (containerHeight - projectHeight) / 2;

project.style.left = `${leftOffset}px`;
project.style.top = `${topOffset}px`;
