Paste the style code to Custom Css:

  width: 215px; height: 124px;
}
@-webkit-keyframes headerBGanimationZip {
  0%{ height: 124px; width: 215px; }
  50%{ height: 80px; width: 215px; }
  100%{ height: 80px; width: 100%; }
}
@-moz-keyframes headerBGanimationZip {
  0%{ height: 124px; width: 215px; }
  50%{ height: 80px; width: 215px; }

Hi, the css does’t work in custom css, so I put the css into child theme’s custom.css: https://www.dropbox.com/s/pznz8j9u4nv8nto/QQ20150325-3.jpg?dl=0
