Does Designing in Sigma Reduce Coding Costs

[Kingalan1]

A design service is using Figma to create modified form. Once the design is complete, Sigma will export CSS files. If we provide these CSS files to a coder, will this greatly reduce the required time to implement the. design on our website?  Our website is designed. with a modified real estate theme.  We are using exactly the same fields and functionality of the previous form.

We are seeking to reduce coding time and subsequent costs.

Thanks,
