What is the design system?

It is a collection of visual components that can be used in different combinations to build digital products. These components should have a properly defined guideline when you use it in your project.

You can think of a box of Lego and you can use small pieces to construct a larger system.

Sometimes when we do the PSD to Responsive HTML conversion jobs we get the design system assets along with the PSD files from the clients. Then our team can refer to that design specification and convert the PSD to pixel perfect HTML files.
