How to Use the Custom Progress Bar Constructor (Configure)
The Constructor helps you quickly create a Custom Progress Bar For YouTube: choose a background, colors, and slider animation, generate a style for YouTube Theme, and apply it via YouTube Customize in the extension.
Open the Constructor
Go to the Constructor page - this is where you create and edit YouTube progress-bar styles.
Upload an Image for the Background
Click the field and select an image, drag & drop a file, or paste a URL. One image at a time is supported. A high-quality background helps craft a striking YouTube Theme.
Configure the Slider
- Size & position: adjust width and margins so the bar stands out without distracting from playback.
- Height: set a comfortable thickness for the progress line.
- Color/gradient: choose a solid color or paste your own gradient in
linear-gradient(...)format - a key to a recognizable YouTube Theme. - Animation: optionally add a subtle effect for the active progress state.
- Reset to return default parameters anytime.
Save & Add to the Extension
Click Save & Add to apply the style in the extension. Your Custom Progress Bar For YouTube will appear in the extension menu and can be enabled in one click. To go back a step, click Cancel.
Tips for an Ideal YouTube Theme
- Contrast: ensure readability in both light and dark YouTube themes.
- Minimal animations: heavy effects may reduce FPS on low-end devices - test on real videos.
- Gradients: use smooth color transitions to emphasize brand style.
- Image quality: prefer high-resolution backgrounds to avoid blur.
