The new Vegan Tuck Box site was created with a ‘responsive’ design, meaning there is no separate mobile site – just a single website that, when viewed in on a small screen, adjusts itself to make it mobile-friendly.
A benefit of having a responsive website (rather than a separate mobile site) is that there is only one website to maintain, which is especially convenient if yours is a eCommerce site or has a lot of frequently-changing content.
