Changing your Bio Page theme
Pick a preset - it sets your whole look in one click.
Pick a theme preset from the Design tab to set your page's background, colors, and type all at once. Presets are grouped into three categories - Light, Dark, and Animated - see Light and dark themes.
Switching presets is non-destructive to your content - only the look changes; your blocks and their content stay exactly as you built them. Fine-tune further with custom colors and fonts afterward.
