Background Setting

Background Color
You may set the background color of you popup. In the case when external content (an external web page as content) you will not be allowed to setup the background color. In that case the background color will be specified by the web page itself. Use the 'Pick' button or simply click on the colored field to open a color picker dialog for easy color selection.

Transparent Background Color
Check this checkbox if you like the background color of you popup to be transparent. In that case the background color set with the Background Color fields will be ignored. If you want to make a popup with a non-rectangular shape then you may use the help of this feature. Once you have checked this check box the background color will be transparent and you could make use of the background image to make your popup for example with a round shape (see setting the background image below). Also you will need to switch off the titlebar, shadow and border.

Background Transparency
You may use the slider or enter a number between 0 and 100 (%) to set the background transparency. If you have checked the Transparent Background Color checkbox, then the background color will always be 100% transparent and you will be setting only the background image transparency. If the Transparent Background Color checkbox is NOT checked then you will be setting the transparency of both the background color and background image.

Background Image settings
You may specify a URL for a background image (either an absolute or a relative URL). The image will appear as background of your popup. In the areas of the image where there are transparent pixels (GIF images for example) you will see the Background Color you have specified. Thus making the background color Transparent only the image will be seen and if the image has for example a round form, and you have switched off the titlebar, border and shadow, then the popup will receive the shape of the background image.
