Step 4: Go to en_GB.html file and use HTML and CSS in your file to style and describe the information as you want.
<style type="text/css"> .yourBodyContainer { } </style> <div class="yourBodyContainer"> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis metus augue, vestibulum eu massa nec, condimentum ornare tellus. Nunc diam ligula, posuere eu neque a, mattis bibendum ante. </div>
