CSS implementation of the triangle, on-line talk a lot, but I found that generally are triangular upward or downward, left to right these two directions seem to speak very little, I tried a bit, found that the original in IE very difficult to engage ~ ~ (Evil IE) ... The
CSS implementation of the triangle principle is: When the width of the element is 0, the border (border) is not 0 o'clock, four corners of the border overlapping 45 degrees angle evenly divided. It's a very awkward speech. Last Picture:
           . Triangle {                
                 border-color:red green Blue pink;
                Border-style: Solid
                Border-width: 20px 20px 20px 20px;
                width:0;
                height:0;
           }

<div class= "triangle"/>
</div>


So, what do we find when we leave a border?

. triangle {
border-color:red transparent transparent transparent;
Border-style:solid;
border-width:20px 20px 0px 20px;
width:0;
height:0;
}



How? Out of the Bar ~ ~

In the same way, we change to a left-to-right

Left:. Triangle {
Border-color:transparent red transparent transparent;
Border-style:solid;
border-width:20px 20px 20px 0px;
width:0;
height:0;
}

Right:. Triangle {
Border-color:transparent transparent transparent red;
Border-style:solid;
border-width:20px 0px 20px 20px;
width:0;
height:0;
}

The merit is caused!? Slow, what kind of browser do you use? If you use non-IE6 words, congratulations! Below we use IE6 (gnashing of teeth ing ... ），



Sweat ~ ~ ~

Originally, IE6 default to the background black ~ ~

Only with the use of IE proprietary East, to solve the bell need to ring people (~_~)

First of all, CSS hack, with the underscore "_"!

_border-top-color:white;
_border-bottom-color:white;
Then use chroma filter: _filter:chroma (color =white);

In fact, it is to filter off the edge!

also add font-size:0; line-height:0;

This completely removes the black background:

. triangle {
Border-color:transparent transparent transparent red;
Border-style:solid;
border-width:20px 0px 20px 20px;
font-size:0;
line-height:0;
width:0;
height:0;
_border-top-color:white;
_border-bottom-color:white;
_filter:chroma (color =white);
}


HTML+CSS:

JS Code
  2. <! DOCTYPE HTML public "-//W3C//DTD html 4.01//en" " http://www.w3.org/TR/html4/strict.dtd" >
  8. <meta http-equiv="Content-type" content= "text/html; Charset=utf-8 ">
  10. <title>css Triangle </title>
  12. <style>
  14. . tiparrow {
  16. / * Color on right, other transparent * /
  18. Border-color:transparent #e00 Transparent transparent;
  20. Border-style:solid;
  22. border-width:6px 6px 6px 0px;
  24. padding:0;
  26. width:0;
  28. height:0;
  30. / * IE6 height fix * /
  32. font-size:0;
  34. line-height:0;
  36. / * IE6 transparent fix * /
  38. _border-top-color: #dddddd;
  40. _border-bottom-color: #dddddd;
  42. _filter:chroma (color = #dddddd);
  44. }
  46. </style>
  50. <body>
  52. <div class="Tiparrow"/>
  54. </div>
  56. </body>

Know some students to directly see the effect, haha: look
