<!--
If you want to include any custom html just before </head>, put it in this file.
Or you can delete these file if you don't need it.
-->
<!-- for example, you could insert this custom css, which makes the bigimg not stretch:
<style>
.intro-header.big-img, .intro-header.big-img  .big-img-transition {
  -webkit-background-size: contain !important;
  -moz-background-size: contain !important;
  background-size: contain !important;
  -o-background-size: contain !important;
  background-color: lightgrey;
}
