Live View rendering vs Design View for CSS Grid layouts

Adobe Dreamweaver provides two distinct rendering environments: the legacy Design View and the Chromium-based Live View. While Live View is designed to mirror modern browser behavior, Design View utilizes an older engine that may not support current CSS3 specifications.

When developing complex responsive layouts using CSS Grid or Flexbox, there is a discrepancy in how elements are positioned and displayed between these two modes. This creates uncertainty when using visual editing tools that may behave differently depending on the active view.

• Does Design View support modern CSS Grid specifications for visual alignment?
• What is the expected behavior when manipulating DOM elements in Live View compared to the static layout blocks in Design View?
