Custom Styling

There are two ways to customize the appearance of VistaView:

1. Update CSS variables - Quick customization using existing variables
2. Create a custom CSS file - Full theme with custom styling

Method 1: Update CSS Variables

The simplest way to customize VistaView is by overriding CSS variables in your own stylesheet.

custom.css

:root {
  /* Colors */
  --vvw-bg-color: #1a1a2e;
  --vvw-text-color: #eee;
  --vvw-bg-opacity: 0.95;
  --vvw-bg-blur: 10px;

  /* UI Colors */
  --vvw-ui-outline-color: #333;
  --vvw-ui-bg-color: #16213e;
  --vvw-ui-text-color: #fff;
  --vvw-ui-hover-bg-color: #0f3460;
  --vvw-ui-active-bg-color: #e94560;

  /* UI Styling */
  --vvw-ui-border-radius: 12px;
  --vvw-ui-border-width: 1px;
}

Import after the base styles:

import 'vistaview/style.css';
import './custom.css';

See the CSS Variables reference for all available variables.

Method 2: Create a Custom Theme

For more control, create a complete custom theme file that includes both variable overrides and custom styling.

my-theme.css

/* Override variables */
:root {
  --vvw-bg-color: #1a1a2e;
  --vvw-text-color: #eee;
  --vvw-ui-bg-color: #16213e;
  --vvw-ui-hover-bg-color: #0f3460;
  --vvw-ui-border-radius: 12px;
}

/* Custom component styling */
.vvw-ui {
  &.vvw-prev,
  &.vvw-next {
    button {
      box-shadow: 0 2px 8px rgba(0, 0, 0, 0.3);

      &:hover {
        transform: scale(1.1);
      }
    }
  }
}

.vvw-bottom-bar,
.vvw-top-bar {
  button {
    transition: all 200ms ease;

    &:hover {
      box-shadow: 0 0 12px var(--vvw-ui-hover-bg-color);
    }
  }
}

Import after the base styles:

import 'vistaview/style.css';
import './my-theme.css';

Accessibility Features

Automatic Reduced Motion Support

VistaView detects the browser’s prefers-reduced-motion setting and automatically disables slide transitions. This happens at runtime - no CSS configuration needed.

High Contrast Mode

@media (prefers-contrast: high) {
  :root {
    --vvw-bg-color: #000;
    --vvw-text-color: #fff;
    --vvw-ui-bg-color: #000;
    --vvw-ui-text-color: #fff;
    --vvw-ui-hover-bg-color: #333;
    --vvw-ui-border-width: 2px;
  }
}
