Can I create a wavy underline as this :

I can only get a solid border :

.err {
  border-bottom:1px solid red;
  display: inline-block;
}

<div>A boy whose name was Peter was <div class="err">woking</div> down the street</div>

Answer 1

Without background image:

.err {
  display: inline-block;
  position: relative;
}
.err:before {
  content: "~~~~~~~~~~~~";
  font-size: 0.6em;
  font-weight: 700;
  font-family: Times New Roman, Serif;
  color: red;
  width: 100%;
  position: absolute;
  top: 12px;
  left: -1px;
  overflow: hidden;
}

<div>A boy whose name was Peter was
  <div class="err">woking</div> down the street</div>

With Background image :

.err {
    display: inline-block;
    position:relative;
    background: url(http://i.imgur.com/HlfA2is.gif) bottom repeat-x;
}

<div>A boy whose name was Peter was <div class="err">woking</div> down the street</div>

Answer 2

Below is an example of one of the ways that you can achieve that without an image. Adjust as needed.

.err {
  border-bottom:2px dotted red;
  display: inline-block;
  position: relative;

}

.err:after {
  content: '';
  width: 100%;
  border-bottom:2px dotted red;
  position: absolute;
  font-size: 16px;
  top: 15px; /* Must be font-size minus one (16px - 1px) */
  left: -2px;
  display: block;
  height: 4px;

  
  }

<div>A boy whose name was Peter was <div class="err">woking</div> down the street</div>

Answer 3

You could use the CSS text-decoration-style property.

-webkit-text-decoration-style: wavy;
-moz-text-decoration-style: wavy;
text-decoration-style: wavy;

However, this is limited to Firefox and Safari. You may need to consider using a image instead.

Answer 4

You can use a :after pseudo-element on the link and set a repeat-x background of a wave image. You can also use the border-image CSS3 property, but this is not fully supported for old browsers
