The bridge factory can be based on the abstract factory class if it
wasn't static. This allows for higher abstraction and makes future
extensions possible. Also, not all parts of RSS-Bridge need to work
on the same instance of the bridge factory.

Notice:
Grid layouts are not supported in very old browser versions:
https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Grid_Layout/CSS_Grid_and_Progressive_Enhancement
This is why @supports checks for browser support (not supported in IE)
https://developer.mozilla.org/en-US/docs/Web/CSS/@supports#Browser_compatibility
In case grid layout is not supported, the displayed form is usable
but not very pretty due to <br> being removed by this commit for
cosmetic reasons (breaks grid layout).
Unfortunately it doesn't seem possible to insert line breaks manually
via '::after { content: '\A' }' in cases where grid layout isn't
supported.
* Add padding to card parameters
Adds padding to parameters to improve readability. For bridges without
parameters (count($parameters) === 0), the parameter 'div' is no longer
created.
* Add colon ':' after label via CSS
* Capitalize first letter of label for readability
* Fix checkbox isn't aligned left
Sets the size of the checkbox to 20x20 px for good measure.
* Harmonize formatting
* Add new style to number and select boxes

* Add fallback solution for browsers without grid support
