Themify is a framework every designer should be using. If you are serious about translating your design ideas to a fully functioning website with an interface that is totally intuitive for designers, then you just cannot look past Themify. It's helped me translate design ideas into websites for clients in no time, offering more than straight photoshop files, rather an entire website.
There are two main reasons I chose Themify for my website. First, is it is highly customizable and mobile friendly, with the Themify builder I can practically make anything. Second, their support team always answers my questions quick (less than 24 hours).
