Responsive Loyalty Website for a Retailer
This Bootstrap-based responsive landing page took me less than eight hours to build.
The designer added me to his Zeplin project (Sketch) where I downloaded assets and styles. This is a part of a larger website that will be available in the following month.

For this landing I used HTML5, CSS3 (transitions), jQuery, and Bootstrap.

It is built using SEO techniques, AMP tags for a quick preview, and Open Graph for Facebook, Twitter, WhatsApp, and Telegram card displays.
