Css Shape Creation Curved Wave

Question

This is what i have got so far After after checking out tutorial

Answer 1

Here is a final demo on the folded corners http://nicolasgallagher.com/pure-css-folded-corner-effect/demo/

and the following code is how you can create them:

    .note {
  position: relative;
  width: 30%;
  padding: 1em 1.5em;
  margin: 2em auto;
  color: #fff;
  background: #97C02F;
  overflow: hidden;
}

.note:before {
  content: "";
  position: absolute;
  top: 0;
  right: 0;
  border-width: 0 16px 16px 0;
  border-style: solid;
  border-color: #fff #fff #658E15 #658E15;
  background: #658E15;
  -webkit-box-shadow: 0 1px 1px rgba(0,0,0,0.3), -1px 1px 1px rgba(0,0,0,0.2);
  -moz-box-shadow: 0 1px 1px rgba(0,0,0,0.3), -1px 1px 1px rgba(0,0,0,0.2);
  box-shadow: 0 1px 1px rgba(0,0,0,0.3), -1px 1px 1px rgba(0,0,0,0.2);
  /* Firefox 3.0 damage limitation */
  display: block; width: 0;
}

.note.rounded {
  -moz-border-radius: 5px 0 5px 5px;
  border-radius: 5px 0 5px 5px;
}

.note.rounded:before {
  border-width: 8px;
  border-color: #fff #fff transparent transparent;
  -moz-border-radius: 0 0 0 5px;
  border-radius: 0 0 0 5px;
}

To create a curved wave effect you can use this code

    <div id="wave"/>
<div/>


#wave {
  position: relative;
  height: 70px;
  width: 600px;
  background: #e0efe3;
}

#wave:before {
    content: "";
    display: block;
    position: absolute;
    border-radius: 100% 50%;
    width: 340px;
    height: 80px;
    background-color: white;
    right: -5px;
    top: 40px;
}

#wave:after {
    content: "";
    display: block;
    position: absolute;
    border-radius: 100% 50%;
    width: 300px;
    height: 70px;
    background-color: #e0efe3;
    left: 0;
    top: 27px;
}

to achieve the curve youll need to inverse where it starts. Follow the same demo just reverse you values.
