Question

我正在寻找 HTML 或 ASCII 字符，这是一个向上或向下的三角形，以便我可以将其用作切换开关。

我找到了↑（↑）和↓（↓） - 但是那些词干很窄。我正在寻找HTML箭头“head”。

Answer 1

Unicode箭头：

▲ - U + 25B2 BLACK UP-POINTING TRIANGLE
▼ - U + 25BC BLACK DOWN-POINTING TRIANGLE
▴ - U + 25B4小黑点三角
▾ - U + 25BE小黑点三角

对于▲和▼，如果不能直接包含Unicode字符，请分别使用▲和▼。（使用UTF-8！）。

请注意，较小版本的字体支持效果不佳。最好使用较小字体的大版本。

更多Unicode箭头位于：

最后，这些箭头不是ASCII，包括↑和↓：它们是Unicode。

Answer 2

适用于HTML实体
◄= ◄
►= ►
▼= ▼
▲= ▲

Answer 3

选项1：UNICODE COLUMN SORT ARROWS

我发现这个对于单个字符列分类器非常方便。 （看起来很好的升级）。

⇕ =⇕

Unicode table column sort arrows

重要提示 （使用Unicode符号时）

Unicode支持因所选符号，浏览器和字体系列而异。如果您发现所选符号在某些浏览器中不起作用，请尝试使用其他字体系列。 Microsoft建议使用"Segoe UI Symbol"但是将字体包含在您的网站中是明智的，因为在他们的计算机上没有多少人使用它。

在其他浏览器中打开此页面，查看使用默认字体呈现的符号。

更多Unicode箭头。

您可以直接从下面的页面复制它们，也可以使用代码。

每行箭头从左到右编号：

0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F

只需在上面的结束分号前插入相应的数字/字母。

Answer 4

抱歉，他们只使用Unicode。：（

大的：

U+25B2（黑色向上三角形▲）
U+25BC（黑色向下三角形▼）
U+25C0（黑色左指三角◀）
U+25B6（黑色右指三角形▶）

大白的：

U+25B3（白色指向三角形△）
U+25BD（白色向下三角▽）
U+25C1（白色左指三角◁）
U+25B7（白色右指三角▷）

还有一些小三角形：

U+25B4（黑色指向小三角形▴）
U+25C2（黑色左指小三角◂）
U+25BE（黑色向下的小三角形▾）
U+25B8（黑色右指小三角▸）

还有一些白色的：

U+25C3（白色左指小三角◃）
U+25BF（白色向下的小三角形▿）
U+25B9（白色右指小三角▹）
U+25B5（白色指向小三角形▵）

还有一些“尖”的三角形。您可以在维基百科上阅读更多内容：
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，则只需使用^和v即可使用图像文件。（~~就像移动版中的谷歌地图~~这指的是古代移动谷歌地图）

正如其他人也建议的那样，你也可以创建带有HTML的三角形，无论是CSS边框还是SVG形状，甚至是JavaScript画布。

CSS

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>

的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();
}

Answer 5

由于您使用这些箭头进行切换开关，您可能需要考虑使用以下样式而不是unicode字符创建带有html元素的箭头。

.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;
}

Answer 6

这些Unicode字符怎么样？

˅

分别为

˄和˅。

Answer 7

有几种正确的方法可以显示向下的三角形。

方法1：使用十进制HTML实体

HTML：

&#9660;

方法2：使用十六进制HTML实体

HTML：

&#x25BC;

方法3：直接使用字符

HTML：

▼

方法4：使用CSS

HTML：

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

CSS：

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

这三种方法中的每一种都应具有相同的输出。对于其他符号，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 Unicode-table.com 等参考网站查找UNICODE支持的图标以及与之对应的代码。例如，您可以在 http://unicode-table.com/en/25BC/ 处找到向下指向三角形的值。

请注意，这些方法仅适用于每个浏览器中默认可用的图标。对于像☃，❄，★，☂，☭，⎗或symbols这样的符号，这种情况的可能性要小得多。虽然可以为其他UNICODE符号提供跨浏览器支持，但程序有点复杂。

如果您想知道如何添加对不太常见的UNICODE字符的支持，请参阅 Create webfont with Unicode Supplementary Multilingual Plane symbols 以获取有关如何执行此操作的详细信息。

背景图片

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本编码将图像嵌入CSS文件中，例如，如下所述。 @ weasel5i2和@Obsidian。我建议使用SVG而不是GIF，但是，对于性能和符号的清晰度来说，这样做会更好。

以下代码是 enter image description here 图标的base64 for和SVG版本：

/* 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的背景图像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，请考虑以下差异：

SVG图片

他们可以有多种颜色
他们可以嵌入自己的CSS和/或由HTML文档设置样式
它们可以作为单独的文件加载，嵌入在CSS中并嵌入HTML
每个符号由XML代码或base64代码表示。您不能直接在代码编辑器中使用该字符或使用HTML实体
当HTML代码嵌入HTML中时，同一符号的多次使用意味着符号的重复。将文件嵌入CSS或将其作为单独文件加载时不需要复制
您无法使用color，font-size，line-height，background-color或其他与字体相关的样式规则来更改图标的显示，但您可以引用不同的组件单独的图标作为形状。
您需要一些SVG和/或base64编码知识
旧版IE中有限或不支持

图标字体

图标只能有一种填充色，一种背景色等
图标可以嵌入CSS或HTML中。在HTML中，您可以直接使用该字符，也可以使用HTML实体来表示它。
可以在不使用webfont的情况下显示某些符号。大多数符号都不能。
同一符号的多次使用意味着当您的角色嵌入HTML时，符号会重复。将文件嵌入CSS时不需要复制。
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图标的显示
您不需要特殊的技术知识
支持所有主流浏览器，包括旧版本的IE

就个人而言，我建议仅在需要多种颜色时才使用背景图像，而这些颜色不能通过color，background-color和其他颜色相关的CSS实现字体规则。

使用SVG图像的主要好处是，您可以为符号的不同组件提供自己的样式。如果将SVG XML代码嵌入HTML文档中，这与HTML样式非常相似。但是，这将导致使用HTML标记和SVG标记的网页，这可能会显着降低网页的可读性。如果符号在多个页面上重复，它还会增加额外膨胀，并且您需要考虑旧版本的IE对SVG没有或有限支持。

Answer 8

“非ASCII（不是↑/↓）”需要资格。

虽然这些字符未在American Standard Code for Information Interchange中定义为字形，但它们的代码WERE通常用于为ASCII代码24和25（十六进制18和19，CANcel和EM：媒介结束）提供图形表示。 Code page 437（由IBM称为扩展ASCII，包括数字代码128到255）定义了这些字形作为ASCII代码的使用，这些惯例的普遍存在渗透到整个行业，正如它们作为标准部署所看到的那样，如HP，尤其是打印机和IBM，特别是从原始PC开始的微型计算机。

正如当时对CAN和EM的ASCII代码的使用相对过时一样，证明它们用作字形是合理的，因此当时使用UNICODE约定时使用代码作为字形已经过时了

应该强调的是，IBM在扩展ASCII中对ASCII进行的扩展，不仅包括数字代码128到255的更大数字集，还扩展了一些数字控制代码的使用，在ASCII范围0到0 32，仅从媒体传输控制协议到包含字形。通常假设错误地说，前0到128没有“扩展”，并且IBM在此范围内使用传统ASCII的字形。此错误也在之前的参考文献中进行过。这个错误变得如此普遍，以至于通过口语方式重新定义了ASCII。

Answer 9

我知道我迟到了，但你也可以通过简单的CSS实现这个目标：

<强> HTML：

（它可以是任何HTML元素，如果你使用像<span>这样的内联元素，请确保使用display:block;使其成为块/内联块元素或display:inline-block）：

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

和

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

<强> 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); 
  }

您也可以使用:before和:after伪元素来完成它，这实际上是一种更好的方法，因为您可以避免创建额外的标记。但这取决于你如何完成它。

Answer 10

空三角形的HTML实体
◁= ◁
▷= ▷
▽= ▽
△= △

Answer 11

▲▼ 这些分别是U + 25B2（&#x25B2）和U + 25BC（&#x25BC）

Answer 12

这里有很多人建议使用三角形，但有时你需要一个雪佛龙。

我们有一个案例，我们的按钮显示一个V形，并希望用户手册以一种非技术用户也能识别的方式参考按钮。所以我们需要一个雪佛龙标志。

我们最后使用了。。它被称为垂直直角支架的演示形式，其代码为U + FE40。

Answer 13

我认为提问者可能指的是其中一个（见附图） - 我在自己搜索同样的事情时发现了这个StackOverflow问题。

不幸的是，这个字形似乎并不是作为一个独特的字符实体存在于任何地方。维基百科通过使用内联javascript和img content =＆＃34; data：image / gif ...＆＃34;来完成下面的工作。实现这个象征。

顺便说一句，这里是base64：

Answer 14

通常，最好是在他的语境中看到一个角色。

以下是完整的Unicode字符列表，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，浏览器版本也在不断发展。

这个列表是通过html实体unicode表的十进制迭代获得的，可能需要几秒钟，但在很多情况下对我来说非常有用。

＆＃13;

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() 


//  From https://codepen.io/Nico_KraZhtest/pen/mWzXqy

＆＃13;

与小书签相同的代码段：

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()}();

这是一个纯文本提取箭头，其中一些是 unicode 10.0 。 http://unicode.org/versions/Unicode10.0.0/

Unicode 10.0增加了8,518个字符，总共136,690个字符。

Answer 15

This one似乎暗示030和031是上下三角形。

（正如bobince指出的那样，这似乎不是ASCII标准）

Answer 16

我使用▼和▲，但它们可能不适合你。我使用alt 11551作为第一个，11550作为第二个。如果ascii与您的系统不同，您可以随时复制粘贴它们。

Answer 17

我认为这里推荐的最受欢迎的符号（▼和▲）看起来太粗体，因此在用户ADJenks推荐的网站codepoints.net上，我发现这些符号更符合我的口味： ?（U + 1F780）?（U + 1F781）?（U + 1F782）?（U + 1F783）

Answer 18

我要用于此的网站是codepoints.net

在这里搜索单词“ arrowhead”和“ triangle”：https://codepoints.net/search?q=arrowhead+triangle

它与一些带有茎的“三角形箭头”匹配，但是只有4个小页面可以略过，而且每个字符都有很多不错的细节。

还有一个“其他符号和箭头”的代码块，该网站在此处列出了它们：https://codepoints.net/miscellaneous_symbols_and_arrows
