Rounded skewed top shape in css

I need to make a div that looks like this:

skewed top with rounded corners

With text in the middle in css. I tried looking at transforms and other 3d stuff, but I couldn't figure it out, especially without ruining the text.

Solution

  • You can use a skewed Y pseudo element as a background of the element. This won't affect the content :

    div {
  position: relative;
  display: inline-block;
  padding: 20px 50px;
  overflow: hidden;
}
div:before {
  content: '';
  position: absolute;
  top: 0; left: 0;
  width: 100%; height: 100%;
  background: #FFD505;
  -webkit-transform-origin: 0 0;
  -ms-transform-origin: 0 0;
  transform-origin: 0 0;
  -webkit-transform: skewY(5deg);
  -ms-transform: skewY(5deg);
  transform: skewY(5deg);
  z-index: -1;
  border-radius: 10px 10px 0 0;
}
    <div>Some text</div>

    • The div has overflow:hidden so that the overflowing parts of the pseudo-element are hidden.
    • The pseudo element has a negative z-index so it stacks behind the content of the div
    • The transform-origin is set to 0 0 so that top left of the skewed pseudo element doesn't move.
