Implementing triangles
Example 1:
#test1{ height:20px; width:20px; border-color:#FF9600 #3366ff #12ad2a #f0ed7a; border-style:solid; border-width:20px;} Example 2:
Based on the above, when the height and width are set to 0, a border slash will appear.
#test2 { height:0; width:0; overflow: hidden; /* 这里设置overflow, font-size, line-height */ font-size: 0; /*是因为, 虽然宽高度为0, 但在IE6下会具有默认的 */ line-height: 0; /* 字体大小和行高, 导致盒子呈现被撑开的长矩形 */ border-color:#FF9600 #3366ff #12ad2a #f0eb7a; border-style:solid; border-width:20px;} Example 3:
In Example 2, you can see that there are 4 triangles. If 4 colors, keep only one color, and set the remaining 3 colors to be transparent or the same as the background color, then form a triangle.
#test3 { height:0; width:0; overflow: hidden; font-size: 0; line-height: 0; border-color:#FF9600 transparent transparent transparent; border-style:solid; border-width:20px;} Example 4:
In Example 3, under IE6, you need to set the remaining three sides If the border-style is dashed, a transparent effect can be achieved.
#test4 { height:0; width:0; overflow: hidden; font-size: 0; line-height: 0; border-color:#FF9600 transparent transparent transparent; border-style:solid dashed dashed dashed; border-width:20px;} Example 5:
The hypotenuses of the small triangles drawn above all rely on the sides of the original box, and there is another form of small triangle, The hypotenuse is on the diagonal of the box.
#test5 { height:0; width:0; overflow: hidden; font-size: 0; line-height: 0; border-color:#FF9600 #3366ff transparent transparent; border-style:solid solid dashed dashed; border-width:40px 40px 0 0 ;} Keeping one of the colors will give you a triangle with the hypotenuse on the diagonal.
Achieve rounded corners effect
Can achieve approximate rounded corners, which is actually displayed by a very small trapezoid.
