哪些字符可用于上 / 下三角形(无茎的箭头)以 HTML 显示?

我正在寻找一个HTMLASCII字符,该字符是向上或向下的三角形,因此可以将其用作切换开关。

我发现↑( ↑ )和↓( ↓ )- 但它们的茎很窄。我只是在寻找 HTML 箭头 “head”。

答案

Unicode 箭头:

  • ▲-U + 25B2 黑色向上指向三角形
  • ▼-U + 25BC 黑色向下指向三角形
  • ▴-U + 25B4 黑色向上指向三角形
  • ▾-U + 25BE 小黑向下指向三角形

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

请注意,较小版本的字体支持不是很好。最好以较小的字体使用大版本。

更多 Unicode 箭头位于:

最后,这些箭头不是 ASCII,包括↑和↓:它们是 Unicode。

对于 HTML 实体
◄= ◄
►= ►
▼= ▼
▲= ▲

选项 1:UNICODE 列排序箭头

我发现这对于单个字符列排序器非常方便。 (看起来不错,高档)

⇕ =⇕

Unicode表列排序箭头

重要说明 (使用 Unicode 符号时)

Unicode 支持取决于选择的符号,浏览器和字体系列。如果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,因为很少有人在计算机上使用它。

在其他浏览器中打开此页面,以查看使用默认字体呈现的符号。


一些 Unicode 箭头。

您可以直接在下面的页面上复制它们,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

只需按照上述在分号前面插入相应的数字 / 字母。

选项 2:纯 CSS 字样

我最近写了一篇文章,内容涉及仅使用 CSS (无需图像)有效地创建人字形

如何简单地更改:

  • 回转
  • 厚度
  • 颜色
  • 尺寸

在 JSFIDDLE 上点击演示


在此处输入图片说明


CSS (有效的跨浏览器支持)

.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 图像图标

上/下 上 / 下

上

仅使用几行 CSS,我们就可以将图像编码为 base64。

优点

  • 无需以图像或字体的形式包含其他资源。
  • 支持完整的 Alpha 透明度。
  • 全面的跨浏览器支持。
  • 小图像 / 图标可以存储在数据库中。

缺点

  • 更新 / 编辑可能会变得很麻烦。
  • 由于生成了过多的代码标记,因此不适合大图像。

的 CSS

.sorting,
.sorting_asc,
.sorting_desc{
    padding:4px 21px 4px 4px;
    cursor:pointer;
}
.sorting{

}

抱歉,它们仅使用 Unicode。 :(

大的:

  • U+25B2 (黑色向上三角形▲)
  • U+25BC (黑色的向下指向三角形▼)
  • U+25C0 (黑色左三角形◀)
  • U+25B6 (黑色右三角形▶)

大白的:

  • U+25B3 (白色向上三角形△)
  • U+25BD (白色向下三角形▽)
  • U+25C1 (白色左三角形 triangle)
  • U+25B7 (白色右三角形▷)

还有一些更小的三角形:

  • U+25B4 (黑色朝上小三角形▴)
  • U+25C2 (黑色左小三角◂)
  • U+25BE (黑色向下的小三角形 triangle)
  • U+25B8 (黑色右小三角形▸)

还有一些白色的:

  • U+25C3 (白色向左的小三角形◃)
  • U+25BF (白色朝下的小三角形▿)
  • U+25B9 (白色右指向小三角形▹)
  • U+25B5 (白色朝上小三角形▵)

还有一些 “尖的” 三角形。您可以在 Wikipedia 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。如果仍要使用 ASCII,则可以仅使用^v使用图像文件。 ( 就像移动版本的 Google 地图一样,它指的是古老的移动版 Google 地图)


正如其他人所建议的那样,您还可以使用 HTML 创建三角形,这些 CSS 可以是 CSS 边框或 SVG 形状,甚至可以是 JavaScript 画布。

的 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();
}

演示版

由于您将这些箭头用于切换开关,因此您可能需要考虑使用以下样式(而不是 Unicode 字符)使用 html 元素创建这些箭头。

.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;
}

http://jsfiddle.net/FrsGR/

间距修饰符字母块中有文字箭头:

U+02C2  ˂   &#706;  Modifier Letter Left  Arrowhead
U+02C3  ˃   &#707;  Modifier Letter Right Arrowhead
U+02C4  ˄   &#708;  Modifier Letter Up    Arrowhead
U+02C5  ˅   &#709;  Modifier Letter Down  Arrowhead

有几种显示向下三角形的正确方法。

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。有些甚至还有第四个选项,允许您使用基于字符串的引用(例如&hearts;显示♥)。

您可以使用Unicode-table.com 之类的参考网站来查找 UNICODE 支持的图标以及它们对应的代码。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,这些方法仅对于每个浏览器中默认可用的图标就足够了。对于 symbols,❄,★,☂,☭,⎗或⎘之类的符号,这种情况的可能性要小得多。尽管可以为其他 UNICODE 符号提供跨浏览器的支持,但过程却有些复杂。

如果您想知道如何添加对不太常见的 UNICODE 字符的支持,请参阅使用 Unicode 补充多语言平面符号创建 webfont,以获取有关如何执行此操作的更多信息。


背景图片

完全不同的策略是使用背景图像代替字体。为了获得最佳性能,最好通过基本编码将图像嵌入 CSS 文件中,如 eg 中所述。 @ weasel5i2 和 @Obsidian。我建议使用 SVG 而不是 GIF,但是这样做对性能和符号清晰度都更好。

以下代码是的 base64 和的 SVG 版本在此处输入图片说明图标:

/* size: 0.9kb */

何时使用背景图片或字体

在许多用例中,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。要决定选择哪一个,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,可以嵌入 CSS 并可以嵌入 HTML
  • 每个符号都由 XML 代码或 base64 代码表示。您不能直接在代码编辑器中使用字符或使用 HTML 实体
  • 当将 XML 代码嵌入 HTML 时,多次使用同一符号表示该符号重复。将文件嵌入 CSS 或将其作为单独的文件加载时,不需要重复
  • 您不能使用colorfont-sizeline-heightbackground-color或其他与字体相关的样式规则来更改图标的显示,但是可以将图标的不同组成部分分别引用为形状。
  • 您需要一些 SVG 和 / 或 base64 编码的知识
  • IE 的旧版本有限或不支持

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。
  • 可以将图标嵌入 CSS 或 HTML 中。在 HTML 中,您可以直接使用字符或使用 HTML 实体来表示它。
  • 不使用网络字体就可以显示某些符号。大多数符号不能。
  • 当您的字符嵌入 HTML 时,多次使用同一符号意味着该符号重复。将文件嵌入 CSS 时不需要复制。
  • 您可以使用colorfont-sizeline-heightbackground-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
  • 所有主要浏览器(包括旧版本的 IE)的支持

就个人而言,我建议仅在需要多种颜色并且无法通过colorbackground-color和其他与颜色相关的 CSS 字体规则来实现这些颜色时,才使用 background-images。

使用 SVG 图像的主要好处是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,则这与样式 HTML 非常相似。但是,这将导致同时使用 HTML 标签和 SVG 标签的网页,这可能会大大降低网页的可读性。如果该符号在多个页面上重复出现,并且您需要考虑到 IE 的旧版本不支持 SVG 或对 SVG 的支持有限,它还会增加额外的膨胀。

“非 ASCII(都不是↑/↓)” 需要限定。

虽然这些字符在美国信息交换标准代码中并未定义为字形,但它们的代码通常用于为 ASCII 代码 24 和 25(十六进制 18 和 19,CANcel 和 EM:媒介末尾)提供图形表示。 代码页 437 (IBM 称为扩展 ASCII,包括数字代码 128 至 255)定义了这些字形作为 ASCII 代码的用法,并且这些约定的普遍性已渗透到整个行业,从诸如 HP,特别是对于打印机和 IBM,特别是对于以原始 PC 开头的微型计算机。

正如当时在 CAN 和 EM 上使用 ASCII 码相对已经过时,证明它们用作字形是合理的,时间的流逝也使得当前使用 UNICODE 约定不再使用字码作为字形。


应当强调的是,IBM 在扩展 ASCII 中对 ASCII 进行的扩展,不仅包括数字代码 128 至 255 的较大数字集,而且还扩展了某些数字控制代码的使用,范围为 ASCII 范围 0 至 32,从只是媒体传输控制协议要包含字形。通常会错误地假定前 0 到 128 没有被 “扩展”,并且 IBM 在该范围内使用了常规 ASCII 的字形。在以前的参考文献之一中也发生了此错误。这个错误变得如此普遍,以至于口头地重新定义了 ASCII 码。

我知道我迟到了,但是您也可以使用简单的 CSS 完成此操作:

HTML:

(它可以是任何 HTML 元素,例如,如果您使用内联元素,例如<span> ,请确保将其设置为具有display:block;display:inline-block的 block / inline-block 元素)

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

<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); 
  }

您也可以使用:before:after伪元素来完成此操作,这实际上是一种更好的方法,因为避免了创建额外的标记。但这取决于您如何完成它。

这是CodePen 中演示,具有许多箭头功能。

这里很多人建议使用三角形,但有时您需要人字形。

我们曾经遇到过这样一个情况,我们的按钮显示人字形,并希望用户手册以非技术用户也可以识别的方式引用该按钮。所以我们需要一个人字形标志。

最后我们使用﹀。它被称为 “垂直直角支架演示表”,其代码为 U + FE40。
