Syntax error on Search Placeholder

Site URL: http://diversify.film

I really want to change the placeholder text in my SP 7.1 website, but I keep getting an error. Is my code wrong? How can I change the placeholder text?

<script>
<div class="sqs-search-ui-text-input sqs-search-ui-button-wrapper color-dark" data-preview="true" data-collection="">
    <div class="spinner-wrapper"></div>
    <input type="search" class="search-input hover-effect" value="" placeholder="Search">
    <div class="yui3-widget sqs-widget sqs-search-preview">
        <div class="sqs-search-preview-content"></div>
    </div>
</div>
  </script>
