css box shadow instead of border

Borders take up space in web browser html

When setting width/height in a component this can have unintended consequences: the size of the component is not as expected. The content area may be less.

A cool solution is to use box-shadow instead of border e.g. 1 px border `box-shadow: inset 0px 0px 0px 1px blue`

Had to fix a tricky bug related to react-select recently (our Dropdown component wraps react-select). Here's the how the bug manifested. Dropdown does not overlay dynamically added content below it Variations of this have been reported since 2017. But I tried all the suggestions in the comments and none worked for me. I also tried wrapping the Dropdown in a div and changing z-index to be higher as well as making absolute position but no success. Changing the elements order in the html source and then reordering using flexbox order does work but it breaks the tabbing flow and is not recommended from an accessibility standpoint. One issue is the Dropdown is in a container and is constrained by the containers z-index. No matter how I change the Dropdowns z-index, its container is stacked below the next in stacking order.
