How to Make Google Slides
Dark Mode
Open your Google Slides presentation.
Click on your profile picture in the top right and select Settings.
Look for Appearance and switch to Dark Mode (if available).
If Dark Mode is not available, install a Dark Mode extension for your browser.
Alternatively, change your theme by selecting a dark background for slides.
Click on Slide > Change background, choose a dark color, and apply it to all slides.
Adjust text and elements to contrast well with the dark background.
