One of the most important rules in profitable web design is: don’t go backward. If you care at all about building custom or semi-custom websites, design sets break that rule immediately. Because they’re so opinionated, design sets require you to constantly un-style and re-style elements. You spend as much time going backward as you do going forward.
On top of that, design sets are usually thrown together as quickly as possible with terrible HTML structure, zero care for accessibility (A11y) compliance, inconsistent and random styling values (usually in pixel values – yuck!), and a lack of custom classes (no scalability or maintainability).
Frames fixes all this – it’s built for people who care about customizability, scalability, and quality craftsmanship with the added benefit of cutting workflow time in half.
