What is fluid-responsive?

As the browser viewport changes size, the design scales with it.

How is this different from vw and vh scaling?

Using vw or vh units is one way to make your content fluid responsive. The problems with this method are:

  • You have to set sizes on every element you want to be fluid responsive.
  • Things could quickly become too small or too large because of a linear scaling.
  • Accessibility suffers because both vw and vh units cannot be affected by browser zooming.
  • It can be challenging to manage and maintain your Webflow project, especially for other developers and clients.

Root-font based scaling is more powerful!

What is root-font based scaling and why is it better?

Client-first system uses rem units for all its sizes, and rem unit is based on only one thing - html root font size.

By modifying this size we are effectively making our rems "larger" or "smaller" visually. Our visual fluid-responsive builder runs on an extensive set of calculations that modify root font size according to your preferences. Adding the generated css code makes your build follow new size scaling rules. All in rems!


  • Continue using Client-first as normal. This new fluid responsive strategy is an optional add-on to Client-first. Add it, or don't add it, to any project.
  • Browsers can zoom normally.
  • Browser font size settings that are modified by end-users will be respected.
  • Maintaining a Webflow project in rems is easier than a project with fixed vw- or vh- based sizing.
