Styling

The component makes use of the .hidden class (This is not included!) which in terms of styling should add:


.hidden {
   display: none !important;
}

The following CSS can be used for styling the button.


// Show more button, used for lists and teasers.
a.show-more-button {
  display: block;
  text-align: center;
  text-transform: uppercase;
  font-family: "gibsonRegular", "Arial", sans-serif;
  font-size: 16px;
  border-radius: 2px;
  line-height: 30px;
  color: white;
  background-color: black;
  cursor: pointer;
  margin-bottom: 10px;
  @media (min-width: 768px) {
    margin-bottom: 20px;
  }
  .boxed & {
    margin-top: 10px;
    margin-bottom: 0;
    @media (min-width: 768px) {
      margin-top: 20px;
    }
  }
}
