twitter-bootstrap - 网页没有响应

问题描述

我想让我的网页响应。它可以工作到 320 像素，但是当我进一步减小屏幕尺寸时，它根本不起作用，只有一半的内容可见。

这是所需的代码

HTML：

<div class="container">
    <div class="row">
        <div class="col-md-6">
            <img
                src="assets/img/profile.png"
                height="520"
                width="500"
                hspace="20"
                class="responsive"
            />
        </div>
        <div class="col-md-6">
            <p>
                Lorem Khaled Ipsum is a major key to success. To succeed you must
                believe. When you believe, you will succeed. Mogul talk. Find peace,
                life is like a water fall, you’ve gotta flow. Lion! Fan luv. Eliptical
                talk.
            </p>
        </div>
    </div>
</div>

CSS：

.responsive {
    max-width: 100%;
    display: block;
    height: auto;
    margin: auto;
}

img {
    float: left;
    margin-left: 20px;
}

@media screen and (max-width: 768px) {
    .nav-menu {
        background-color: #ffffff;
    }

    .nav-toggle:hover {
        background-color: transparent;
    }

    .nav-toggle span {
        background-color: #dfdfdf;
    }

    .nav-toggle span:hover {
        background-color: #fff;
    }
}

它工作正常，直到大约 320 像素：

但是在进一步缩小到小于 320px 之后，图像不适合屏幕：

提前致谢！

这是我所做的：

我删除了imgand.responsive样式并使用了 Bootstrap.img-fluid类（在此处查看）：

/* Deleted, because it isn't relevant anymore. */

      <div class="col-md-6">

        </p>
      </div>
    </div>
  </div>

</body>
</html>

我在我的电脑上试了一下。图像宽 1150 像素，但视口只有 300 像素宽。图像完美适应：

希望能帮助到你。
