CSS：是否可以使元素看起来像正弦/余弦函数？

Question

On my page I want elements that will serve as horizontal "breaks" in the same way as hr elements, but I would like them to be shaped like a sine function.

Is that possible? If so, how?

Here's a fiddle for you to complete: http://jsfiddle.net/pdov7u85/

HTML:

<p>Here's some red text</p>
<!--some element with id someElement will go here-->
 <p>Here's some blue text, which should be divided from the red text with a wavy line</p>

CSS:

p:nth-of-type(1)
{
    color: red;
}

#someElement
{

}

p:nth-of-type(2)
{
    color: blue;
}

Answer 1

Challenge accepted.

 .sine { text-align: center; } .sine_span { display: inline-block; margin:0; padding:0; height: 20px; width: 40px; border: 1px solid black; } .sine_span_first { border-bottom: none; border-radius: 20px 20px 0 0; transform: translate(-20px, 0) scale(2,1); } .sine_span_second { border-top: none; border-radius: 0 0 20px 20px; transform: translate(20px, 20px) scale(2,1); } .sine_span_first_2 { transform: translate(0, 20px) scale(1,2); } .sine_span_second_2 { transform: translate(0, 60px) scale(1,2); } 

 Flat curve <div class="sine"> <span class="sine_span sine_span_first"></span><span class="sine_span sine_span_second"></span> </div> <br /> Sharp curve <div class="sine"> <span class="sine_span sine_span_first sine_span_first_2"></span><span class="sine_span sine_span_second sine_span_second_2"></span> </div> 

Btw, shouldn't you use some gif image for this?

Answer 2

You could draw that sine function in javascript:

var canvas = document.getElementById("canvas");
if (canvas == null || !canvas.getContext) {
    return;
}
var ctx = canvas.getContext("2d");
ctx.beginPath();
ctx.lineWidth = 1;
ctx.strokeStyle = "rgb(11,153,11)";

for (var i = 0; i <= 1000; i++) {

    var x = i * 5;
    var y = Math.sin(5 * x + 1);
    ctx.lineTo(0.5 + x, 25 - y * 24);
}
ctx.stroke();

Or you could just use an SVG image like Paulie_D suggested.

Answer 3

As @Paulie_D said don't over think it.

Be semantic and use a HR, give it a height and a background image.

hr{ 
    border:none; 
    height:82px; 
    background:url('http://i60.tinypic.com/df8y75.png'); 
    background-size:50%;
  }

eg.

note: background-size is not supported in older versions of IE but I only used it for convenience.
