Currently the cards shown in the tools column of the Content Translation editor use a fake 3d shadow style that was deprecated.
Cards should be updated in the following aspects:
- Remove the border and the fake shadow at the bottom.
- Use a 1px shadow with 1px blur based on 15% opacity black color.
- Adjust the spacing inside and outside the cards.
I created a code pen illustrating the intended style and mockups below with the spacing specification and the final expected result:
Adjusting the grey color used as background is also needed but it was filled as a separate ticket (T158401)
