Benefits of CSS Box Shadow
CSS box-shadow is a powerful tool for creating depth and visual hierarchy in web design. Unlike images, shadows are generated by the browser, making them lightweight and scalable. They automatically adapt to element size, support animation, and can be changed dynamically via JavaScript. Using box-shadow improves site performance compared to using graphic shadows.
CSS Box Shadow FAQ
Blur controls shadow softness - higher values create softer shadows. Spread changes shadow size - positive values increase, negative values decrease the shadow size relative to the element.
Technically there is no limit, but for optimal performance it is recommended to use no more than 3-4 shadows per element.
Inset shadow is an inner shadow that appears inside the element, creating an embossed or recessed effect.
Box-shadow can impact performance with a large number of shadowed elements or during animation. It is recommended to use moderately and optimize for complex scenarios.
