# Client-First

In plain words

Client-First is a naming convention and class structure created by Webflow for organizing CSS classes in a consistent, scalable way. It underlies many custom systems, including Yungle's own Lumos convention, and its purpose is to keep large Webflow projects maintainable as they grow.

Example

In Client-First a hero heading might use the classes heading-style-h1 and padding-section-large, so anyone who knows the convention can read the structure at a glance.

    ## How Much Does Webflow Web Design Cost?

    Professional Webflow design typically ranges from $6,000 to $20,000+ for a custom marketing site, depending on page count, CMS complexity, and how much strategic work (messaging, UX, SEO) is included. Webflow's own hosting costs are minimal — usually $20-40/month — so most of your budget goes to the design and build itself, not ongoing platform fees. That's different from WordPress, where plugin costs and maintenance add up over time even after a cheaper initial build.
