wp-content/themes/customtheme/index.php

<style>
.jumbotron {
  /* Permalink - use to edit and share this gradient: http://colorzilla.com/gradient-editor/#1e5799+0,2a8ee0+31,207cca+100,7db9e8+100 */
  background: #1e5799; /* Old browsers */
  background: -moz-linear-gradient(left,  #1e5799 0%, #2a8ee0 31%, #207cca 100%, #7db9e8 100%); /* FF3.6-15 */
