You can add a background image to your buttons in order to give them a specific look.
Example of Button with background:
To enable the use of background on your button all you need to do is click on the "Visible" check box and select the background image you want to apply to your web button through the "Choose" button. It will then automatically be set as background on your web button. Finally, you can also define its position as tile, stretched or centered accordingly.
If you do not want to insert an image but instead want to add a color as background, do not enable the "Visible" check box and just select from the "Background Color" section the color you want from the color picker in order to apply it accordingly. Automatically the color you select will be set as background.
