当我只使用 CSS 和 HTML 时，内容在加载时跳跃

Question

我有一个内部票务系统，它不允许 JS 并且也不完全允许所有 CSS 标签。 出于这个原因，我不得不调整所有可能的方法来为某些图像构建一个简单的 CSS 滑块（仅使用 CSS 和 HTML ）。

我唯一的问题是，每当我单击 Next/Prev 按钮时，都会创建 Jump 效果，然后加载下一张图片。我试图找到一种方法，在加载下一张图片时图片保持在同一位置。 我已经尝试过max-width: 100%; height: auto; 但仍然没有:( .

有什么建议？？？提前非常感谢

基本上你的图像在跳跃，因为你没有固定 padding-top，因此 #slide 的总高度正在改变

<div id="slidepicswrap">
        <div id="slides">
            <div id="pic1">
                <img src="https://unsplash.it/g/500/350?random" alt="Image 1" width="500" height="350" />
                <div>
                    <a class="previous" href="#pic5" rel="nofollow">&lt;</a>
                    <a class="next" href="#pic2" rel="nofollow">&gt;</a>
                </div>

                <h3>Image 1</h3>
                <p>Text of image 1.</p>
            </div>
            <div id="pic2"><img src="https://unsplash.it/g/500/350" alt="Image 2" width="500" height="350" />
                <div>
                    <a class="previous" href="#pic1" rel="nofollow">&lt;</a>
                    <a class="next" href="#pic3" rel="nofollow">&gt;</a>
                </div>
                <h3>Image 2</h3>
                <p>Text of image 2.</p>
            </div>
            <div id="pic3"><img src="https://unsplash.it/g/500/350?random" alt="Image 3" width="500" height="350" />

                    <a class="previous" href="#pic2" rel="nofollow">&lt;</a>
                    <a class="next" href="#pic1" rel="nofollow">&gt;</a>
                </div>

                <p>Text of image 3.</p>
