我在寻找一个指向上或下的三角形HTML或ASCII字符，以便我可以将其用作切换开关。

我找到了 ↑ （↑）和 ↓（↓）- 但这些都有一个狭窄的干茎。我只要寻找HTML箭头"头部"。

如果您想保持简单，可以使用插入符号 "^"（即 Shift-6）和小写字母 "v"。根据您指定的字体，它们将看起来像箭头。 - user229044

这里有一个快速的方法，在一个页面上找到它们：http://amp-what.com/#q=triangle - ndp

前往搜索并查找“triangle”http://www.fileformat.info/info/unicode/index.htm，http://nwmtwd.com/misc_character_sets.html 这里缺少三角形，但这是一个有用的摘要。 - Jonathan Root

选项 2：纯 CSS 尖角

您可以仅使用 CSS 高效地创建尖角，无需图像。

(不需要图片)

很容易进行以下操作:

旋转
粗细
颜色
大小

在 JSFIDDLE 上查看演示

enter image description here

CSS (跨浏览器支持高效)

.chevron {
  position: relative;
  display: block;
  height: 50px; /*height should be double border*/
}

.chevron::before,
.chevron::after {
  position: absolute;
  display: block;
  content: "";
  border: 25px solid transparent; /*adjust size*/
}

/* Replace all text `top` below with left/right/bottom to rotate the chevron */

.chevron::before {
  top: 0;
  border-top-color: #b00; /*Chevron Color*/
}

.chevron::after {
  top: -10px; /*adjust thickness*/
  border-top-color: #fff; /*Match background colour*/
}

<i class="chevron"></i>

选项 3: CSS BASE64 图标

上 / 下

向上

只需几行CSS代码，我们就可以将图像编码为base64。

点击 JSFIDDLE 上的演示

优点

无需包含其他形式的图像或字体资源。
支持完全透明度。
具有完全跨浏览器支持。
小型图像/图标可以存储在数据库中。

缺点

更新/编辑可能会变得麻烦。
对于大型图片不太适用，因为会生成过多的代码标记。

还有一些较小的三角形: • U+25B4 (黑色朝上的小三角形 ▴) • U+25C2 (黑色朝左的小三角形 ◂) • U+25BE (黑色朝下的小三角形 ▾) • U+25B8 (黑色朝右的小三角形 ▸)

也有一些白色的: • U+25C3 (白色朝左的小三角形 ◃) • U+25BF (白色朝下的小三角形 ▿) • U+25B9 (白色朝右的小三角形 ▹) • U+25B5 (白色朝上的小三角形 ▵)

还有一些“尖锐”的三角形。您可以在维基百科上阅读更多：http://en.wikipedia.org/wiki/Geometric_Shapes 但不幸的是，它们都是Unicode，而不是ASCII。如果您仍想使用ASCII，则可以使用图像文件或只使用^和v。（就像移动版Google Maps一样）

正如其他人建议的那样，您还可以使用HTML创建三角形，无论是使用CSS边框、SVG形状还是JavaScript画布。

div{
    width: 0px;
    height: 0px;
    border-top: 10px solid black;
    border-left: 8px solid transparent;
    border-right: 8px solid transparent;
    border-bottom: none;
}

SVG

<svg width="16" height="10">
    <polygon points="0,0 16,0 8,10"/>
</svg>

JavaScript

var ctx = document.querySelector("canvas").getContext("2d");

// do not use with() outside of this demo!
with(ctx){
    beginPath();
    moveTo(0,0);
    lineTo(16,0);
    lineTo(8,10);
    fill();
    endPath();
}

在间距修饰字母块中有直接箭头：

U+02C3  ˃   &#707;  Modifier Letter Right Arrowhead
U+02C4  ˄   &#708;  Modifier Letter Up    Arrowhead
U+02C5  ˅   &#709;  Modifier Letter Down  Arrowhead

这种方法可能更有用于屏幕阅读器等辅助功能。 - Mark Stewart

如果您正在使用这些箭头来切换开关，您可能希望考虑使用以下样式创建具有HTML元素的箭头，而不是使用Unicode字符。

.upparrow {
   height: 0;
   width: 0;
   border: 4px solid transparent;
   border-bottom-color: #000;
}

.downarrow {
   height: 0;
   width: 0;
   border: 4px solid transparent;
   border-top-color: #000;
}

一个正方形元素的四条边相交成45度角，因此只需涂色其中一条边，就能得到一个三角形。您可以在这里查看示例：http://jsfiddle.net/FrsGR/ - Magnus Magnusson

有几种正确的方法可以显示一个向下指的三角形。

方法1: 使用十进制HTML实体

HTML:

&#9660;

方法二：使用十六进制 HTML 实体

HTML：

&#x25BC;

方法三：直接使用字符

HTML：

▼

方法四：使用CSS

HTML：

<span class='icon-down'></span>

CSS：

.icon-down:before {
    content: "\25BC";
}

每种方法应该都有相同的输出。对于其他符号，也存在相同的三个选项。有些甚至有第四个选项，允许您使用基于字符串的引用（例如&hearts; 来显示 ♥）。

您可以使用类似 Unicode-table.com 等参考网站查找在 UNICODE 中支持哪些图标及其对应的代码。例如，您可以在 http://unicode-table.com/en/25BC/ 上找到指向下三角形的值。

请注意，这些方法仅适用于每个浏览器默认提供的图标。对于像☃、❄、★、☂、☭、⎗ 或 ⎘这样的符号，情况远不如此。虽然可以为其他 UNICODE 符号提供跨浏览器支持，但过程会更加复杂。

如果您想了解如何添加对较少见的 UNICODE 字符的支持，请参阅 Create webfont with Unicode Supplementary Multilingual Plane symbols 以获取更多信息。

背景图像

另一种完全不同的策略是使用背景图像而不是字体。为了获得最佳性能，最好通过对其进行基础编码将图像嵌入到CSS文件中，正如 @weasel5i2 和 @Obsidian 所提到的那样。然而，我建议使用 SVG 而不是 GIF，因为它既有助于性能，又有助于您的符号的清晰度。

以下代码是

图标的 SVG 版本的 base64。

/* size: 0.9kb */
url(data:image/svg+xml;base64,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

何时使用背景图片或字体

对于许多用例，基于SVG的背景图片和图标字体在性能和灵活性方面基本相同。要决定选择哪个，请考虑以下区别：

SVG图像

它们可以具有多种颜色
它们可以嵌入自己的CSS和/或通过HTML文档进行样式设置
它们可以作为单独的文件加载，嵌入到CSS中或嵌入到HTML中
每个符号由XML代码或base64代码表示。您无法直接在代码编辑器中使用字符或使用HTML实体
在将XML代码嵌入HTML时，相同符号的多个使用意味着符号的重复。在将文件嵌入CSS或作为单独的文件加载时，不需要重复。
您不能使用color、font-size、line-height、background-color或其他与字体相关的样式规则来更改您的图标的显示方式，但您可以分别引用图标的不同组件作为形状。
您需要了解一些SVG和/或base64编码知识
在旧版本的IE中支持受限或没有支持

图标字体

一个图标只能具有一种填充颜色、一种背景颜色等
一个图标可以嵌入到CSS或HTML中。在HTML中，您可以直接使用字符或使用HTML实体表示它。
一些符号可以在不使用webfont的情况下显示。大多数符号不能。
在将字符嵌入HTML时，相同符号的多个使用意味着符号的重复。在将文件嵌入CSS时不需要重复。
您可以使用color、font-size、line-height、background-color或其他与字体相关的样式规则来更改您的图标的显示方式
您不需要任何特殊的技术知识
在包括旧版本IE在内的所有主要浏览器中均受支持

就我个人而言，我建议仅在需要多种颜色且这些颜色无法通过color、background-color和其他与颜色相关的CSS规则来实现时，才使用背景图片。

使用SVG图像的主要优点是，您可以为符号的不同组件提供自己的样式设置。如果将SVG XML代码嵌入HTML文档中，则这非常类似于对HTML进行样式设置。然而，这将导致一个网页同时使用HTML标记和SVG标记，从而可能大大降低网页的可读性。如果该符号在多个页面中重复出现，则还会增加额外的冗余，并且您需要考虑旧版本的IE不支持或支持有限的SVG。

通常情况下，最好在上下文中查看字符。

这是Unicode字符的完整列表，以及您的浏览器当前如何显示它们。我看到这个列表不断发展，一个浏览器版本接着一个。

这个列表是通过十进制迭代html实体unicode表获得的，可能需要一些时间，但在许多情况下对我非常有用。

通过快速悬停给定的字符，您将获得十进制和十六进制以及使用键盘生成它的快捷方式。

var i = 0
    do document.write("<a title='(Linux|Hex): [CTRL+SHIFT]+u"+(i).toString(16)+"\nHtml entity: &# "+i+";\n&#x"+(i).toString(16)+";\n(Win|Dec): [ALT]+"+i+"' onmouseover='this.focus()' onclick='this.href=\"//google.com/?q=\"+this.innerHTML' style='cursor:pointer' target='new'>"+"&#"+i+";</a>"),i++
    while (i<136690)
window.stop()

相同的代码片段作为书签：

javascript:void%20!function(){var%20t=0;do{document.write(%22%3Ca%20title='(Linux|Hex):%20[CTRL+SHIFT]+u%22+t.toString(16)+%22\nHtml%20entity:%20%26%23%20%22+t+%22;\n%26%23x%22+t.toString(16)+%22;\n(Win|Dec):%20[ALT]+%22+t+%22'%20onmouseover='this.focus()'%20onclick='this.href=\%22https://google.com/%3Fq=\%22+this.innerHTML'%20style='cursor:pointer'%20target='new'%3E%26%23%22+t+%22;%3C/a%3E%22),t++}while(t%3C136690);window.stop()}();

生成该列表的php代码：

for ($x = 0; $x < 136690; $x++) {
  echo html_entity_decode('&#'.$x.';',ENT_NOQUOTES,'UTF-8');
}

为了将该列表生成到控制台，使用php：

php -r 'for ($x = 0; $x < 136690; $x++) { echo html_entity_decode("&#".$x.";",ENT_NOQUOTES,"UTF-8");}'

以下是一些箭头的纯文本提取，其中一些带有unicode 10.0。 http://unicode.org/versions/Unicode10.0.0/

Unicode 10.0增加了8,518个字符，总计136,690个字符。

嘿，你是否注意到普通的html <details> 元素有一个下拉箭头？有时这就是我们所需要的。

<details> <summary>Morning</summary> <p>Hello world!</p> </details> <details> <summary>Evening</summary> <p>How sweat?</p> </details>

这看起来很有帮助。你知道如何判断某些浏览器是否支持Unicode 10吗？我查看了https://caniuse.com/#search=unicode%2010，但似乎没有说明。 - Ryan

很难说。对于像Chromium这样的Linux免费浏览器，它并不是开箱即用的，但我们可以安装额外的字体。最完整的可能是emojione：https://github.com/emojione/emojione - NVRM

"Not ASCII (neither's ↑/↓)" 需要说明。

虽然这些字符在美国信息交换标准代码中没有定义为字形，但它们的编码通常用于为ASCII代码24和25（十六进制18和19，CANcel和EM：Medium结束）提供图形表示。代码页437（由IBM称为扩展ASCII，包括数字代码128到255）将这些字形定义为ASCII代码，并且这些约定的普及渗透了整个行业，正如它们被领先公司（如惠普，特别是打印机，和IBM，特别是从原始PC开始的微型计算机）部署为标准所示。

正如在当时使用ASCII代码进行CAN和EM相对过时，可以证明它们作为字形的使用，随着时间的推移，通过当前使用的UNICODE约定，代码的使用作为字形已经过时。

需要翻译的内容：强调IBM在扩展ASCII中所做的扩展不仅包括数字代码128到255的更大数字集，还将ASCII范围0到32的一些数字控制代码的使用从媒体传输控制协议扩展到字形。通常错误地认为第0到128个字符没有"扩展"，IBM正是在这个范围内使用传统ASCII的字形。这个错误也出现在之前的参考资料中。这个错误变得如此普遍，以至于它在潜意识中被重新定义了ASCII。

我知道我来晚了，但你也可以使用纯CSS来实现这个：

(它可以是任何HTML元素，如果你正在使用内联元素例如<span>，请确保将其转换为块级元素或内联块元素，使用display:block;或display:inline-block)：

<div class="up"></div>

和

<div class="down"></div>

CSS：

.up {
   height:0;
   width:0;
   border-top:100px solid black;
   border-left:100px solid transparent;
   transform:rotate(-45deg);   
  }

.down {
   height:0;
   width:0;
   border-bottom:100px solid black;
   border-right:100px solid transparent;
   transform:rotate(-45deg); 
  }

你还可以使用:before和:after伪元素来实现它，这实际上是更好的方法，因为你避免了创建额外的标记。但如何实现取决于你。

这里是一个在CodePen中演示了许多箭头可能性的演示。

- Ricardo Zea

虽然在纯CSS中能够实现这一点很不错，但是存在一些问题，例如Firefox或IE中缺乏阴影支持，在浪费了数小时之后，我又回到了Unicode箭头。 - direct00

@direct00 你没有理解重点。如果你知道你正在以某种方式设计你的箭头，你会立刻知道哪种方法最适合你的需求。如果你浪费了时间，那不是我的解决方案的问题，而是你自己的问题。也不需要那种态度。祝你好运。 - Ricardo Zea

Unicode箭头指示：

▲ - U+25B2 黑色上三角形
▼ - U+25BC 黑色下三角形
▴ - U+25B4 小型黑色上三角形
▾ - U+25BE 小型黑色下三角形

如果无法直接使用Unicode字符（请使用UTF-8！），则对于▲和▼，请分别使用▲和▼。

请注意，小型版本的字体支持不太好。最好在较小的字号中使用大型版本。

最后，这些箭头不是ASCII字符，包括↑和↓：它们是Unicode字符。
