What characters can be used for up/down triangle (arrow without stem) for display in HTML?
我在找一个HTML或ASCII字符,它是一个向上或向下的三角形,这样我就可以把它用作切换开关。
我找到了↑(
Unicode箭头:
- ▲-U+25B2实心上指三角
- ▼-U+25BC黑色下指三角形
- ?-U+25B4小实心上指三角
- ?-U+25Be小黑下指三角
对于▲和▼如果不能直接包含Unicode字符,则分别使用
请注意,对较小版本的字体支持没有那么好。最好使用较小字体的大版本。
更多的Unicode箭头位于:
- http://en.wikipedia.org/wiki/arrow_28symbol%29 arrows_Unicode格式
- http://en.wikipedia.org/wiki/Geometric_形状
最后,这些箭头不是ASCII,包括↑和↓:它们是Unicode。

选项1:Unicode列排序箭头
我发现这一个对于单个字符的列分类非常方便。(按比例放大后看起来不错)。

赞成的意见
- 不需要以图像或字体的形式包含其他资源。
- 支持完全透明度。
- 全面的跨浏览器支持。
- 小图像/图标可以存储在数据库中。
欺骗
- 更新/编辑可能会变得很麻烦。
- 由于生成的代码标记过多,不适用于大型图像。

还有一些"尖角"三角形。你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。如果您仍然想使用ASCII,那么您可以使用一个图像文件,只需使用就像移动版的谷歌地图一样这是指古老的移动谷歌地图)
正如其他人所建议的,您也可以用HTML创建三角形,既可以使用CSS边框,也可以使用SVG形状,甚至可以使用JavaScript画布。
CSS1 2 3 4 5 6 7 8 | div{ width: 0px; height: 0px; border-top: 10px solid black; border-left: 8px solid transparent; border-right: 8px solid transparent; border-bottom: none; } |
静止无功发生器
1 2 3 | <svg width="16" height="10"> <polygon points="0,0 16,0 8,10"/> </svg> |
JavaScript
1 2 3 4 5 6 7 8 9 10 11 | 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
由于使用这些箭头作为切换开关,您可能需要考虑使用HTML元素创建这些箭头,使用以下样式而不是Unicode字符。
1 2 3 4 5 6 7 8 9 10 11 12 13 | .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; } |

这三种方法中的每一种都应该有相同的输出。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(如
您可以使用类似unicode-table.com的参考网站来查找unicode支持哪些图标以及它们对应的代码。例如,您可以在http://unicode table.com/en/25bc/找到下指三角形的值。好的。
请注意,这些方法仅适用于默认情况下在每个浏览器中可用的图标。对于像这样的符号??,,???还是?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,但过程有点复杂。好的。
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,以了解有关如何执行此操作的详细信息。好的。背景图像
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,最好通过基本编码将图像嵌入到CSS文件中,如@weasel5i2和@obsidian所述。不过,我建议使用SVG而不是GIF,这对性能和符号的清晰度都更好。好的。
以下代码是图标的base64 for和svg版本:好的。

何时使用背景图像或字体
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上是等效的。要决定选择哪个,请考虑以下差异:好的。
SVG图像好的。
- 它们可以有多种颜色
- 它们可以嵌入自己的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,嵌入在HTML中。
- 每个符号都由XML代码或base64代码表示。不能在代码编辑器中直接使用字符或使用HTML实体
- 当XML代码嵌入到HTML中时,多次使用同一符号意味着符号重复。在CSS中嵌入文件或将其作为单独文件加载时,不需要复制
- 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图标的显示,但可以单独引用图标的不同组件作为形状。 - 您需要了解SVG和/或base64编码
- 旧版本IE的支持有限或不支持
图标字体好的。
- 图标只能有一种填充色、一种背景色等。
- 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实体来表示它。
- 某些符号可以不使用WebFont显示。大多数符号不能。
- 当您的字符嵌入到HTML中时,多次使用同一符号意味着符号重复。在CSS中嵌入文件时不需要复制。
- 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。 - 你不需要特殊的技术知识
- 支持所有主要浏览器,包括旧版本的IE
就我个人而言,我建议仅当您需要多种颜色时才使用背景图像,而这些颜色无法通过
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。如果您将SVG XML代码嵌入到HTML文档中,这与HTML的样式非常相似。然而,这将导致网页同时使用HTML标记和SVG标记,从而显著降低网页的可读性。如果符号在多个页面上重复出现,并且需要考虑旧版本的IE对SVG的支持没有或有限,那么它还会增加额外的膨胀。好的。好啊。
"非ASCII(也不是↑/↓)"需要限定。
虽然这些字符在美国信息交换标准代码中没有被定义为标志符号,但它们的代码通常用于为ASCII代码24和25(Hex 18和19,Cancel和Em:媒体结束)提供图形表示。代码页437(IBM称为扩展的ASCII,包括数字代码128到255)定义了这些符号作为ASCII代码的使用,这些约定的普遍性渗透到业界,正如惠普(特别是打印机)和IBM(特别是以T开头的微型计算机)等领先公司将它们作为标准部署所看到的那样。他原来的PC.
正如对can和em使用ASCII代码在当时是相对过时的,证明它们作为glyphs的使用是合理的,时间的推移也使得代码作为glyphs的使用被当前使用的unicode约定所淘汰。
应该强调的是,IBM在扩展的ASCII中对ASCII的扩展不仅包括一个更大的数字集,用于数字代码128到255,而且还扩展了一些数字控制代码的使用,在ASCII范围0到32,从媒体传输控制协议扩展到包括字形。通常错误地假定,前0到128没有被"扩展",并且IBM正在为这个范围使用传统的ASCII符号。此错误也在以前的一个引用中发生。这个错误变得如此普遍,以至于它在口头上下意识地重新定义了ASCII。
我知道我迟到了,但你也可以用简单的CSS来完成:
HTML:
(它可以是任何HTML元素,例如,如果您使用像
和
CSS:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | .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); } |
