When building a media gallery that combines both images and videos in a Masonry grid, you need to pay special attention to how each media type is displayed. Mixing images and embedded videos can introduce layout challenges because images and videos often have different aspect ratios and loading behaviors. To maintain a visually pleasing and consistent grid, ensure that all media elements—regardless of type—are styled with similar dimensions, spacing, and margins. Use CSS to set maximum widths, responsive heights, and object-fit properties so that both images and videos align neatly within the Masonry columns. It’s also important to account for the asynchronous loading of videos and images, as this can affect the Masonry layout calculations. By treating all media elements with consistent styling and considering their unique loading characteristics, you can achieve a seamless, Pinterest-style gallery that feels cohesive and professional.
