CSS adjustments to improve readability for bridge parameters (#763)

* Group common selectors
* Fix indentation using tabs
* Use same styles for number and text inputs
* Use grid layout for parameters

Introduces the grid layout for bridge parameters. All parameters are
arranged in a grid to improve readability. Read more on grid layouts

- https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Grid_Layout

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

References #797

* Add fallback solution for browsers without grid support
