Box Shadow Generator

The Box Shadow Generator is a free online tool designed to create custom CSS box-shadow properties with real time visual feedback. It is perfect for web developers and UI designers who want to add depth and dimension to their web elements.

How the Box Shadow Generator works

  1. 1

    Add Your Content

    Start by adjusting the sliders for horizontal offset, vertical offset, blur radius, and spread radius. You can also pick your desired shadow color and choose between inset or outset shadows.

  2. 2

    Format Your Data

    As you tweak the settings, the tool instantly calculates the exact CSS syntax required for your design. It updates the live preview panel so you can see how the shadow interacts with your element in real time.

  3. 3

    Get Your Results

    Once you are happy with the visual result, grab the generated CSS code from the output box. Simply copy and paste the box-shadow property directly into your stylesheet.
