Transparent & Overlay Hover

Transparent and overlay hover effects allow you to display image titles, descriptions, and buttons over thumbnails with a semi-transparent background.

This effect improves readability while keeping the image visible underneath.

Robo Gallery supports overlay styling in both:

  • Classic Gallery
  • Fusion Gallery

Classic Gallery – Transparent Hover Setup

Go to:

THUMBS → Hover Options

Make sure:

Hover Mode → Options

Step 1 — Set Background Overlay Color

Adjust:

Bg Color

Example:

rgba(0, 0, 0, 0.5)

This creates a dark transparent overlay.

Classic Hover Options

The last value in rgba() controls transparency:

  • 0 = fully transparent
  • 1 = solid color
  • 0.4–0.7 = recommended overlay range

Step 2 — Customize Hover Colors

Under Text colors and Highlight options, configure:

  • Hover Title Color
  • Hover Description Color
  • Hover Background Color
  • Highlight Title
  • Highlight Description

Classic Hover Colors


Creating a Light Overlay

Example:

rgba(255, 255, 255, 0.6)

This produces a soft white overlay.

Best used with dark text colors.

THUMBS → Hover Effect

When to Use Overlay Hover

  • Portfolio galleries
  • Product showcases
  • Travel galleries
  • Editorial layouts

Overlay hover keeps the layout clean while providing contextual information on interaction.
