title: What are the ways to change the banner/carousel on frequently updated sites
body: <p>Suppose there is a carousel of latest deals on my website. I need to update the images in the carousel frequently(say every second day) due to new offers. One way I can do this is by fetching the details of the offers(banner_img_url, product link, title, etc.) using an ajax request in JSON format and then create the elements dynamically. </p>
  
  <p>I am wondering what are the other ways to update this portion of the page in any other probably better way. I have just heard of server side tempelating also but don't have good idea.</p>
  
  <p>Any suggestions will be helpful.</p>
