I’m experimenting with a small landing page built on Bootstrap 4 for a fashion side project where I share outfits from an <a href="https://thevintagearena.com/">internet thrift store</a> and simple wardrobe basics. Right now I’m using a basic container/row/column layout with images, short descriptions, and buttons, and I’d like advice on best practices for making it responsive and lightweight—especially tips on structuring cards or grids for products, optimizing images, and keeping the CSS clean while still leaving room to grow the page later.
