似乎无法让下载属性发挥作用

我刚刚开始学习 html 所以我想尝试使用 download 属性我刚刚开始学习 html，所以我想尝试使用下载属性 <a href="../images/clunk.jfif" download="ur_mum"> <img src="../images/clunk.jfif" alt="ur mum" width="200" height="200"> </a> 图像存储在同一个网站上，但是当我单击它而不是下载时，它只会使图像全屏显示。我尝试尽可能地排除故障，但没有成功我能找到的关于为什么某些文件类型发生这种情况但并非所有文件类型的原因是这个答案关于pdf下载与预览的类似问题 - 如果可以的话，请将以下标头添加到服务器端的图像响应中： Content-Disposition: attachment; filename=clunk.jfif 或者，您可以使用自定义 onclick 处理程序替换锚标记，该处理程序将图像转换为数据 URL 并触发下载： <img src="../images/clunk.jfif" width="200" height="200" onclick="downloadImage(this)"> const downloadImage = async (img) => { // fetch the image's media type const mediaType = fetch(img.currentSrc, { method: 'HEAD' }) .then(res => res.headers.get('content-type')) .catch(() => 'image/png' /* default to png if request fails */) // place the image on a canvas element const canv = Object.assign(document.createElement('canvas'), { width: img.naturalWidth, height: img.naturalHeight, }) const ctx = canv.getContext('2d') ctx.drawImage(img, 0, 0) // download the canvas data const a = Object.assign(document.createElement('a'), { download: 'filename', href: canv.toDataURL(await mediaType), }) a.click() }

如何使整个跨度落入新行？

这个片段显示了我想要的： http://jsfiddle.net/945Df/3/ 阿根廷圣达菲罗萨里奥。这个片段显示了我想要的： http://jsfiddle.net/945Df/3/ <div class="sup" id="pr"> <strong> <a href="#">Rosario, Santa Fe, Argentina.</a> <span class="date">17 de septiembre de 2013.</span></strong> </div> <div class="sup"> <strong> <a href="#">Rosario, Santa Fe, Argentina.</a> <span class="date">17 de septiembre de 2013.</span> </strong> </div> 当div的宽度（在项目中，视口）没有更多空间时，我希望跨度落入新行。抱歉我的解释不好。我不知道该怎么做。谢谢！编辑：在第二个示例中，短语“SEPTIEMBRE DE 2013”。落入新行。但“17 DE”字样仍位于上行。我想要“2013 年 9 月 17 日”。落入新行。明白了吗？如果您希望跨度不换行，而是完全移动到其他文本下方，您可以使用 white-space: nowrap; .date { text-transform: uppercase; color:#848484; white-space:nowrap; } 演示要让span在空间不足时跳到下一行，可以设置为display: inline-block; .date { display: inline-block; ... } 检查这个：http://jsfiddle.net/945Df/7/ 这就是我实现它的方法： #spantomovedown{ clear: both; display: inline-block; width: 100%; } .date{display:inline-block;} 当日期比div长时，换行显示示例：http://jsfiddle.net/TqRyK/ 如果你漂浮：对；当不再有空间容纳整个内容时，它应该落到下一行。之后您将需要一个清除元件。我通过以下方式实现了它 word-wrap: break word;

CSS 在窄屏幕上显示每个单元格一行的表格

我的 HTML 看起来有点像这样我的 HTML 看起来有点像这样 <html><body><table> <thead><tr><th>A</th><th>B</th><th>C</th><th>D</th><th>E</th></tr></thead> <tbody> <tr><td>1A</td><td>1B</td><td>1C</td><td>1D</td><td>1E</td></tr> <tr><td>2A</td><td>2B</td><td>2C</td><td>2D</td><td>2E</td></tr> <tr><td>3A</td><td>3B</td><td>3C</td><td>3D</td><td>3E</td></tr> </tbody> </table></body></html> 每一行代表一个对象，列是它的属性。实际上，单元格值相当长——有时甚至有 20-30 个字符长。它在大多数设备上渲染良好，但在较小的手机上可能会出现问题。我知道我可以在狭窄的设备上抑制某些列，但在这个特定的情况下感觉不太好。目前我的桌子上有 x-overflow: scroll，但我更希望有一些 CSS 可以使表格在窄设备上呈现得更像这样： A: 1A B: 1B C: 1C D: 1D E: 1E ----- A: 2A B: 2B C: 2C D: 2D E: 2E ----- (etc) 我了解如何测试设备宽度，因此出于这个问题的目的，我们假设我想无条件地执行此操作。稍微更改一下 HTML 标记就可以了，例如添加额外的类或属性，尽管我想使用 <table> 元素来保留它，每个逻辑行有一个 <tr>。这是为了向后兼容，因为我知道有相当多的用户会抓取该网站（尽管存在更简洁的 API）。由于内部政治，如果可能的话，我宁愿避免需要 Javascript 的解决方案（并且无论如何，如果需要，我知道如何编写 JS 解决方案）。我可以做到这一点，但我不知道如何从这里硬编码为“X”的字段名称开始： thead { display: none; } table, tr, td { display: block; } tr + tr { border-top: thin solid black; } td::before { content: "X:"; display: inline-block; width: 2em; } 我见过很多网站都在做这种事情，但目前我正在努力寻找一个在 CSS 中做这件事的网站。看起来这应该是一个常见问题，但我很难知道要搜索哪些术语，因此可能会在这里或其他地方错过一些很好的解释。你就快到了。可能会使用例如data-col 元素上的 <td> 属性并在 CSS 中引用它们 content 上的 :before thead { display: none; } table, tr, td { display: block; } tr+tr { border-top: thin solid black; } td::before { content: attr(data-col)':'; display: inline-block; width: 2em; } <table> <thead> <tr> <th>A</th> <th>B</th> <th>C</th> <th>D</th> <th>E</th> </tr> </thead> <tbody> <tr> <td data-col="A">1A</td> <td data-col="B">1B</td> <td data-col="C">1C</td> <td data-col="D">1D</td> <td data-col="E">1E</td> </tr> <tr> <td data-col="A">2A</td> <td data-col="B">2B</td> <td data-col="C">2C</td> <td data-col="D">2D</td> <td data-col="E">2E</td> </tr> <tr> <td data-col="A">3A</td> <td data-col="B">3B</td> <td data-col="C">3C</td> <td data-col="D">3D</td> <td data-col="E">3E</td> </tr> </tbody> </table> ABCD

带有边框半径和粘性标题的 HTML 表格

我有一个 HTML ，带有边框半径和使用位置的粘性标题：sticky，如下所示： https://codepen.io/muhammadrehansaeed/pen/OJpeeKP 但是，当使用滚动时我有一个带有 <table> 的 HTML border-radius 和使用 position: sticky 的粘性标题，如下所示： https://codepen.io/muhammadrehansaeed/pen/OJpeeKP 但是，当使用粘性标题滚动时，表格行会伸出粘性标题的圆角所在的位置。请参阅此图片的左上角：有没有办法可以在使用粘性标题向下滚动时保持圆角，或者在标题变得粘性并从原始位置向下移动时删除粘性标题？理想情况下，我想要一个CSS解决方案。您可以使用伪元素隐藏边框的某些部分： table thead th:first-child::before, table thead th:last-child::after { width: 1px; height: 5px; background: white; content: ""; display: block; position: absolute; top: 0px; } table thead th:first-child::before { left: -1px; } table thead th:last-child::after { right: -1px; } 正如Ivan建议的那样，似乎使用伪元素来覆盖标题下方不需要的边框是（令人惊讶的）唯一可行的选择。我建议使用伪不仅用于覆盖“外部”区域，而且还用于绘制弧线和填充“内部”区域。可以使用堆叠背景来做到这一点。应用于原始代码： /* § Additions / Changes */ table thead th { position: relative; } /* Pseudos exceeding header boundary by border width; with rectangle covering half circle and rest of height */ table thead th:last-child::after, table thead th:first-child::before { content: ""; position: absolute; top: 0; bottom: 0; left: calc(-1 * var(--global-border-width-1)); width: var(--global-border-radius); background-image: linear-gradient(to bottom, transparent var(--global-border-radius), var(--global-title-color) 0), radial-gradient(circle at var(--global-border-radius) var(--global-border-radius), var(--global-title-color) var(--global-border-radius), var(--global-content-background-color) 0); background-position: top left; background-size: var(--global-border-diameter) 100%, var(--global-border-diameter) var(--global-border-diameter); background-repeat: no-repeat; } table thead th:last-child::after { left: auto; right: calc(-1 * var(--global-border-width-1)); background-position: top right; } /* § Declarations and original style */ html { --global-content-background-color: white; --global-title-color: black; --global-background-color: lightblue; --global-border-color: black; --global-border-radius: 20px; --global-border-width-1: 10px; --global-space-fixed-2: 10px; --global-space-fixed-3: 15px; --global-border-diameter: calc(2 * var(--global-border-radius)); background-color: var(--global-content-background-color); } table { color: var(--global-title-color); background-color: var(--global-content-background-color); border-collapse: separate; border-color: var(--global-title-color); border-style: solid; border-radius: var(--global-border-radius); border-width: 0 var(--global-border-width-1) var(--global-border-width-1) var(--global-border-width-1); border-spacing: 0; width: 100%; } table thead { position: sticky; top: 0; z-index: 10; } table thead th { color: var(--global-background-color); background-color: var(--global-title-color); padding: var(--global-space-fixed-2) var(--global-space-fixed-3); vertical-align: bottom; } table tbody td { border-top: var(--global-border-width-1) solid var(--global-border-color); padding: var(--global-space-fixed-2) var(--global-space-fixed-3); vertical-align: top; } table tbody tr:last-child td:first-child { border-bottom-left-radius: var(--global-border-radius); } table tbody tr:last-child td:last-child { border-bottom-right-radius: var(--global-border-radius); } /* § Unrelated / demo */ * { scroll-margin-top: calc(var(--global-space-fixed-2) * 4 + 1rem); /* = height of sticky thead + top padding of cell, provided text in thead does not wrap */ scroll-margin-bottom: 1em; } td { height: 60vh; } td a { float: right } tr:last-child td { vertical-align: bottom; } a[name]:empty::before { content: attr(name); } th:not(#\0):hover::before { background-image: linear-gradient(to bottom, transparent var(--global-border-radius), #0F08 0), radial-gradient(circle at center, #00F8 var(--global-border-radius), #F2F4 0); background-position: top left; background-size: var(--global-border-diameter) 100%, var(--global-border-diameter) var(--global-border-diameter); } <table> <thead> <tr> <th>Fake non-transparent "border-radius"</th> </tr> </thead> <tbody> <tr> <td> <a href="#⬆️" name="⬇️"></a> For fixed header</td> </tr> <tr> <td> <a href="#⬇️" name="⬆️"></a> Using CSS stacked background images in pseudo elements</td> </tr> </tbody> </table> 只需从表格中删除边框，并为表格主体中的第一个和最后一个表格单元格添加左右边框： tbody td:first-child { border-left: 1px solid black; } tbody td:last-child { border-right: 1px solid black; } tbody tr:last-child td{ border-bottom: 1px solid black; } tbody tr:last-child td:first-child { border-bottom-left-radius: 2px; } tbody tr:last-child td:last-child { border-bottom-right-radius: 2px; } 当然是使用适当的缩进、嵌套和变量！使用许多伪选择器看起来样式相当丑陋，但似乎可以解决您的问题。有一个更紧凑的解决方案。只需将具有背景颜色的框阴影添加到第一个 < th > 和最后一个 < th > 即可隐藏元素。在此示例中，在右侧，您可以看到表格行由于边框半径而可见。在左边，我应用了盒子阴影。盒子阴影：0 -2.1rem 0 .6rem #E5E7EB；在这里，它是灰色的，以便您可以看到它的工作原理，但您只需使用与背景相同的颜色即可使其完全不可见。这是最终结果以及我正在使用的代码： th:第一个孩子 { 边界半径：0.75rem 0 0 0；左边框：.1rem 实心 $color-gray-200；框阴影：0 -2.1rem 0 .6rem $color-gray-200； } th：最后一个孩子{ 边界半径：0 0.75rem 0 0；右边框：.1rem 实心 $color-gray-200；盒子阴影：1rem -2.1rem 0 .6rem $颜色白色； } 可能需要调整框阴影以隐藏基于所选边框半径的行。不确定你是否熟悉jquery，如果熟悉的话你可以在滚动内容时动态更改 border-top-left-radius: 等于粘性标题的半径，但这对于新手来说有点棘手jquery/JS。其次，您可以将粘性标题封闭到父级（例如class="parent")），并将父级背景设置为白色，没有边框。并保持粘性标题的边框半径不变。因此，当您滚动内容时将位于该父级下方（例如 class="parent"）。为了确保父级出现在该行上方，您可以给出 z-index: 10
