Style

None / Plain / Gradient / Image

Define the style of the background.
- None : default background. Keep the css settings of the current Joomla template.
- Plain : the background is filled with one unique color.
- Gradient : the background is filled with a gradient between two colors.
- Image : the background is filled with an image.

 

Plain background

Color : the background is filled with the color setting.
Hover color : the color of the background will change if you move your mouse over the background. Leave the hover color empty if you want to keep the default color. When you define a hover color for the header of a panel, the color will change when the mouse goes hover any place in the panel.
Opacity : in percentage. You can choose a semi-transparent color, of full colored. From 0% (full transparent) to 100% (full color).
 

Tip : when you add a hover color, choose a color very close to the normal color to avoid excessive effect.

 

Gradient background

Direction : of the gradient fill between the two colors. 
Color - End color : the background is filled starting from the color with a progressive change to the end color..
Hover color - End hover color : the colors of the background will change if you move your mouse over the background. Leave the hover colors empty if you want to keep the default colors. When you define hover colors for the header of a panel, the color will change when the mouse goes hover any place in the panel.
Opacity : in percentage. You can choose a semi-transparent color, of full colored. From 0% (full transparent) to 100% (full color).

Tip : choosing two very close colors in a vertical gradient can give a little depth and relief in a discreet way.
