The Custom Header settings
The Theme offers the flexibility to customize the appearance of the header section at the top of each Post/Page. You can set a background image with opacity or no opacity, use a solid color, and get creative with the blending of those two.
At the bottom of every post and/or page you create you will see a panel titled “Custom Header Settings”. Here’s where you can customize this section:
Custom title: This is the main message in big bold type (Be Bold + Enjoy Life).
Custom Sub title: What you will enter here will appear as a subtitle under the main message.
Background image: This is the image that will appear as a background for this section. If you select multiple images, then they will appear as a slider. You can set the speed of the transitions under Cluster > Theme Options > Site Settings.
Background Opacity: This sets an optional opacity for the background image. If you do not want it to have any opacity, set this to 100.
Background color: This sets a background color for the section. If you have used an image with opacity, then this will be handy, as it will affect the color tone. Otherwise this will not have any effect. Leaving it blank will use the default background color which can be customized at the Theme options. So, adding a value to any of these fields will override the default values.
The default values are defined under Cluster > Theme Options. There you can define the settings on a global scope under Site Settings tab. Whatever you set there will be used as default for the header appearance throughout the site.
Remember that you can customize the appearance and titles for every single page/post at the individual page/post page.
