Use the theme editor to customize the header's components and display cart icon in the header, display search icon in the header, use the alternate header, and upload a logo with inverted color.
Display cart icon in the header
Toggling the Show cart icon option displays an icon of a cart (or basket) that will take visitors directly to their shopping cart (or basket) when selected.
Display search icon in the header
Enable the Show search icon option to display an icon of a magnifying glass—the universal "Search" symbol—that will open a search box when clicked.
Use the alternate header
If your header's colors and full-bleed slideshow images are conflicting, use the Color override dropdown menu to adjust header colors and set them to either white or black (depending on your content). This option will override the custom header colors only for the home page and product pages, ensuring your header and slideshow contrast one another.
Upload a logo with inverted color
Using the alternate works best when you upload an alternate logo for those pages. You can do that by clicking Select image in the Alternate logo image box. For instance, if you have a black logo, create a white version of it and it will appear better on darker backgrounds.
