Question

我想要做的是当我将鼠标悬停在网页上的三个图像中的每个图像上时，每个图像下方都会显示三个弹出框，每个图像都有不同的文本，但每次我将鼠标悬停在每个图像上时弹出当我将鼠标悬停在每个图像上时，文本停留在第三个图像右侧的相同位置，并且没有文本发生变化。我不太确定我做错了什么？到目前为止，这是我的代码。

Answer 1

首先，您的HTML格式不正确。您没有关闭<a>元素

其次，CSS样式中有<span>个元素

第三，你将div放在右下方。

这是我通过更改某些内容而制作的fiddle

HTML

<img src="sabatinaslogo.jpg" width="735" height="190" alt="Sabatina's logo" />
<p style="font-size: large">Hover over a photo to read about the pasta dish and its nutrition information.</p>
<div id="links">
    <div class="tooltip-wrap">
        <table style="text-align: center">
            <tr>
                <td>
                    <a>
                        <img class="picture" src="http://fakeimg.pl/250x100/" width="250" height="100" alt="Fettucine" />


                        <div class="tooltip-content"> 
                            <p>Ingredients include:enriched durum flours, egg, water, soy lecithin. Nutritional facts: Approximately 200 calories, 3.2% total fat, 12.5% cholesterol, 16.7% protein, 1.7% calcium and 8.3% iron</p>
                        </div></a>
                </td>
                <td> <a><img class="picture" src="http://fakeimg.pl/250x100/" width="250" height="100" alt="Lasagna" />
        <div class="tooltip-content"> <p>Ingredients include: ground beef, cheese, enriched pasta and tomato sauce. Nutritional facts: Approx. 377 calories per serving, 13% fiber, approx. 50% protein, and approx. 35% sodium</p>
            </div></a>

                </td>
                <td> <a><img class="picture" src="http://fakeimg.pl/250x100/" width="250" height="100" alt="Ravioli" />
        <div class="tooltip-content"> <p>Ingredients include: water, durum wheat semolina, beef, wheat flour, egg, vegetable oil, salt, onion flavoring, tomatoes, sugar, cornflour, herb extracts, salt, garlic salt, spice extracts, black pepper.

        </div></a>

                </td>
        </table>
    </div>

CSS

#links;
demo {
    font: 1 em sans-serif;
    padding: 5px 10px;
    margin: 0px 0px 1px, border-right: 5px color: #ff1828
}
div.links:hover {
    border-right: double 5px;
    color:white
}

.tooltip-wrap {
    position: relative;
}
.tooltip-wrap .tooltip-content {
    display: none;
    position: absolute;
    top: 0;
    top: 100px;
    width: 180px;
    background-color: #000000;
    color:#ffffff;
    padding: 5px;
    margin: 10px;
}
a:hover .tooltip-content {
    display: block;
}

工具提示？我需要弹出文本显示在每个图像下面
