Possible disadvantages of Webflow Flexbox UI Builder

    For those completely new to flexbox or web design, there might be an initial learning curve to fully understand all of the features and capabilities of the builder.
  • Limited to Webflow Environment
    The tool is part of the Webflow ecosystem, meaning designers are tied to Webflow's platforms for both design and hosting, which may limit flexibility for those who prefer other environments.
  • Dependency on Internet
    Since it's an online tool, a stable internet connection is necessary, which can be a disadvantage in environments with unreliable connectivity.
  • Subscription Costs
    While Webflow offers a free tier, advanced features—including those related to flexbox—may require a subscription, potentially increasing costs for design teams or freelancers.
  • Mobile Responsiveness Adjustments
    Although the Flexbox allows for responsive design, complex layouts sometimes need additional tweaks in Webflow's designer to ensure that they work seamlessly across all devices.

    We also need to talk about Source Order vs. Tab Order—they’re more different than you’d expect 👀. Source Order is the sequence of nxodes inside their parent in the DOM. Tab Order is the sequence of focusable nodes navigated using the Tab key. If a focusable element lacks tabindex, it follows a depth-first traversal of Source Order (visualized conceptually as a traversal path). Want to visualize Source Order?... - Source: dev.to / 22 days ago
