# Header Styling
***
## Icon Size
Sets the size of every icon in the mobile header — menu toggle, search, cart, and account — from one place.
Text label sizes are set separately on each block. This setting affects icons only.
***
## Color Scheme
Sets the background, text, and icon colors for the mobile header, separately from the desktop header. The header doesn't take its colors from the page, so always pick a color scheme here.
***
## Transparent Header
When the header floats over a section as a transparent overlay, it uses a separate color scheme so text and icons stay readable against the section behind it. See [Transparent Header](/helix/header-group/mobile-header/transparent-header.md) for which sections can trigger it.
