In Webflow, you manage aspect ratios primarily by wrapping images/elements in a container, setting the container’s width to 100% and position to relative, then positioning the image absolutely within it; you control the ratio using percentage-based values. padding-top (e.g., 100% for square, 56.25% for 16:9) on the container.
Newer methods also include using Webflow’s built-in “Aspect Ratio” property to set predefined or custom ratios (1:1, 16:9, 4:3, etc.) directly on elements, or applying custom CSS via Embeds for advanced control.
Key Takeaway: The padding method creates an aspect ratio box, while the built-in property offers direct control, both ensuring elements scale proportionally across different screen sizes.
