Customize a theme
Click Appearance then click Customizer to customize the current theme installed on your store
Check the Advanced box to make changes to more colors.
Customizer allows you to change the main font, colors, layout (choose full or boxed), main background graphic, and the cart image.
If you are familiar with css you can also use the custom css box to enter your own.
*Customizer works with the Second theme and the Default theme. It may work for certain elements of other pre-designed themes but is not guaranteed. If you would like to make changes to the backgrounds, fonts or colors of any theme Customizer does not work with please see: Customizing pre-designed themes
When you are happy with your changes in Customizer click the save button at the top of the page near Advanced.
Click the X to exit Customizer.
