<!-- Rails automatically strips tags when outputting strings with html on them -->
<%= '<div>You are not alone</div>' %>

<!-- However, you may want to escape the HTML so that you can display the tags in the output -->
<%= h '<div>This will display with escaped html tags</div>' %>

<!-- There are some instances where you would want text with tags to be actually rendered -->
<%= raw '<div>I will be a div</div><br /><span>I will be under div</div>' %>
