html - Creating a Tab shape with CSS or SVG

Question

Does anyone have an idea how to make this tab like shape :

Answer 1

Here is an alternate approach using CSS3 transforms for achieving the required shape. Like the SVG answer, this method can also be used when the background (behind the shape) is not a solid color.

The snippet has two samples and

• One uses transform: skew(45deg) and overflow: hidden on the parent to hide the skewed area on the left side.
• Other uses a rotateX transform with a bit of perspective to produce the skewed/angled side. The transform-origin setting means that only one side is angled.

div.a {
  position: relative;
  height: 70px;
  width: 250px;
  margin-top: 20px;
  padding: 24px 4px 0px;
  overflow: hidden;
}
div.a:before {
  position: absolute;
  content: '';
  top: 20px;
  left: 0px;
  width: 100%;
  height: 50px;
  background: #c94935;
  z-index: -1;
}
div.a:after {
  position: absolute;
  content: '';
  top: 0px;
  left: -20px;
  width: 60%;
  -webkit-transform: skew(45deg);
  -moz-transform: skew(45deg);
  transform: skew(45deg);
  height: 20px;
  background: #c94935;
  z-index: -1;
}
div.b {
  position: relative;
  height: 50px;
  width: 250px;
  padding: 4px 4px 0px;
  margin-top: 40px;
  background: #c94935;
}
div.b:before {
  position: absolute;
  content: '';
  top: -20px;
  left: 0px;
  width: 50%;
  height: 20px;
  -webkit-transform-origin: left top;
  -moz-transform-origin: left top;
  transform-origin: left top;
  -webkit-transform: perspective(10px) rotateX(5deg);
  -moz-transform: perspective(10px) rotateX(5deg);
  transform: perspective(10px) rotateX(5deg);
  background: #c94935;
