Frequently Asked Questions

What types of overlays can I create?

You can create solid color overlays with a single color, or gradient overlays that transition between two colors. Both types support custom opacity levels and various CSS blend modes for different visual effects.

How do blend modes affect the overlay?

Blend modes determine how the overlay color interacts with the background image. 'Normal' simply places the color on top, while modes like 'multiply', 'overlay', and 'screen' create different color mixing effects for more creative results.

Can I upload my own images for testing?

Yes! You can upload your own images to see exactly how the overlay will look on your specific content. This helps you fine-tune the colors and opacity for the best visual result.

How do I implement the generated CSS?

The generated CSS uses a pseudo-element (::before) to create the overlay. Simply copy the CSS and apply the 'overlay-container' class to your image container. The overlay will automatically position itself over the background image.

Are there preset overlays I can use?

Yes! We provide several professional presets including dark, light, colored, and gradient overlays. These presets are optimized for common use cases like hero sections and image cards.

Will the overlays work on mobile devices?

The generated CSS is fully responsive and works across all modern browsers and devices. The overlays will maintain their appearance on desktop, tablet, and mobile screens.
