FAQ Frequently Asked Questions

What do the different shadow values control?
Horizontal offset moves shadow left/right, vertical offset moves it up/down, blur radius controls softness, spread expands/contracts the shadow size, and color sets the shadow appearance. Inset creates inner shadows instead of outer.
Can I create multiple shadows on one element?
Yes, CSS supports multiple box shadows separated by commas. You can layer different shadows for complex effects like multiple light sources or combining outer and inner shadows for depth.
How do I create realistic shadow effects?
For realistic shadows, use subtle offsets (2-4px), moderate blur (4-8px), darker semi-transparent colors (rgba), and position shadows below and slightly offset from elements to simulate natural lighting.
Do box shadows affect layout or performance?
Box shadows do not affect element layout or positioning - they are purely visual. However, complex shadows with large blur values can impact rendering performance, especially on mobile devices or with many elements.
Can I copy the CSS code directly?
Yes, the tool generates complete CSS box-shadow properties that you can copy and paste directly into your stylesheets. The code works in all modern browsers without vendor prefixes.
