我正在寻找一个HTML或ASCII字符，这是一个三角形指向向上或向下，以便我可以使用它作为拨动开关。
我找到了↑(↑)和↓(↓) -但它们的词干很窄。我只是寻找HTML箭头“头”。
当前回答
这里很多人建议用三角形，但有时你需要一个雪佛龙。
我们有一个例子，我们的按钮显示了一个雪佛龙，并希望用户手册以一种非技术用户也能识别的方式引用按钮。所以我们需要一个雪佛龙标志。
最后我们使用了﹀。它被称为直角括号表示表，代码为U+FE40。
其他回答
这个似乎暗示030和031是上下三角形。
(正如bobince指出的，这似乎不是ASCII标准)

我知道我迟到了，但你也可以用普通的CSS来完成这个:
HTML:
(它可以是任何HTML元素，如果你正在使用一个内联元素，例如<span>，确保你使它成为一个block/内联块元素display:block;或显示:inline-block):
<div class=“up”></div>
and
<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);
}
您还可以使用: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。但这取决于你想如何完成它。

这是CodePen中的一个演示，有许多箭头的可能性。
选项1:unicode列排序箭头
I found this one very handy for a single character column sorter.(放大后看起来不错)
⇕ = ⇕

选项2:纯CSS v字形
您可以只使用CSS有效地创建v形标志
(不需要图片)。
这很容易操作:
旋转 厚度 颜色 大小
点击查看jsfiddle上的演示
CSS (高效的跨浏览器支持)
.chevron { 位置:相对; 显示:块; 高度:50 px;/*高度应该是双边框*/ ｝ .chevron::, {后.chevron:: 位置:绝对的; 显示:块; 内容:“”; 边框:25px实体透明;/ * * /调整大小 ｝ /*用左/右/下替换下面所有的' top '以旋转*/ {前.chevron:: 上图:0; border-top-color: # b00;* / / *雪佛龙颜色 ｝ {后.chevron:: 前:-10像素;/ * * /调整厚度 border-top-color: # fff;/*匹配背景颜色*/ ｝ 雪佛龙<我类= " " > < / i >
选项3:CSS base64图像图标
UP - DOWN
下来
UP
只需使用几行CSS，我们就可以将图像编码为base64。
点击查看jsfiddle上的演示
PROS
不需要以图像或字体的形式包含额外的资源。 支持完全alpha透明。 全面的跨浏览器支持。 小图像/图标可以存储在数据库中。
CONS
更新/编辑可能会成为一个麻烦。 不适合大图像，因为生成了过多的代码标记。

Unicode箭头头:
▲- u + 25b2黑色向上三角形 ▼- u + 25bc黑色下指向三角形 ▴- u + 25b4黑色小向上三角形 ` ` ` ` ` ` ` ` ` ` ` ` ` ` u + 25be黑色向下三角形
对于▲和▼使用▲和& # x25BC;如果不能直接包含Unicode字符(使用UTF-8!)
注意，对较小版本的字体支持不是很好。最好使用小字体的大版本。

最后，这些箭头不是ASCII，包括↑和↓:它们是Unicode。
