To create a hero section with four images forming a curved layout, consider using CSS properties that allow for creative positioning and shaping. Techniques such as CSS transforms and the clip-path property can help achieve asymmetrical designs. For instance, you can apply transformations to each image to adjust their size and position, creating a visual flow from larger to smaller images. Additionally, using the clip-path property allows you to define custom shapes for your images, enabling the creation of unique curves and angles. By combining these methods, you can design a dynamic and visually appealing hero section that guides the viewer's eye across the images in the desired curvature.
