我在next.js 13中做了一些项目。这是我的代码的一部分，我试图实现滚动条使用顺风css。

<div className="flex w-[1020px]  p-4 overflow-x-scroll">
    <div
      className={` w-[300px] h-[300px] self-center relative`}
      onClick={() =>
        window.open("https://sagarmathamis.netlify.app/", "_blank")
      }
    >
      <Image src={mis} alt="" layout="fill"></Image>
    </div>
    <div
      className={` w-[300px] h-[300px] self-center relative`}
      onClick={() =>
        window.open("https://revampnewsportal.netlify.app/", "_blank")
      }
    >
      <Image src={newsportal} alt="" layout="fill"></Image>
    </div>
    <div
      className={` w-[300px] h-[300px] self-center relative `}
      onClick={() =>
        window.open("https://onlinesstores.netlify.app/", "_blank")
      }
    >
      <Image src={onlinestore} alt="" layout="fill"></Image>
    </div>
    <div
      className={` w-[300px] h-[300px] self-center relative`}
      onClick={() =>
        window.open("https://searcheproducts.netlify.app/", "_blank")
      }
    >
      <Image src={searchproduct} alt="" layout="fill"></Image>
    </div>
    <div
      className={`bg-teal-500 w-[300px] h-[300px] self-center`}
      onClick={() =>
        window.open(
          "https://www.linkedin.com/in/roshan-ojha-78832a1aa/",
          "_blank"
        )
      }
    ></div>
    <div
      className={`bg-red-500 w-[300px] h-[300px] self-center`}
      onClick={() =>
        window.open(
          "https://www.linkedin.com/in/roshan-ojha-78832a1aa/",
          "_blank"
        )
      }
    ></div>
    <div
      className={`bg-green-500 w-[300px] h-[300px] self-center`}
      onClick={() =>
        window.open(
          "https://www.linkedin.com/in/roshan-ojha-78832a1aa/",
          "_blank"
        )
      }
    ></div>
    <div
      className={`bg-blue-500 w-[300px] h-[300px] self-center`}
      onClick={() =>
        window.open(
          "https://www.linkedin.com/in/roshan-ojha-78832a1aa/",
          "_blank"
        )
      }
    ></div>
  </div>

字符串
但滚动条不显示。div的所有元素都被压缩在父（1020px）div中，如图所示

我该怎么做才能让它可滚动？请帮帮忙。
