Is your feature request related to a problem? Please describe.
Currently, only Background Color can be set for components. To create more expressive applications, it would be wishful to have the possibility to add Background Images to Components.

Describe the solution you'd like
Add a Property to set Background Images for Components, at least for the following Components:

• Table
• Container's
• Image
• Form
• Signature

To do so, add the Style CSS property: "background-image", "background-position", "background-repeat" and "background-size".

Allowed values for background-image should be:

• URL
• conic-gradient
• linear-gradient
• radial-gradient
• repeating-conic-gradient
• repeating-linear-gradient
• repeating-radial-gradient
  -none

Describe alternatives you've considered
