This patch centres the ‘Got it’ button on the vertical axes for desktop, and on the horizontal axes for mobile.

There are some lint warnings:

/home/tn/workspace/eclipse/openvsx/openvsx/webui/src/components/banner.tsx
  42:55  warning  Trailing spaces not allowed  no-trailing-spaces
  43:46  warning  Trailing spaces not allowed  no-trailing-spaces

other than the lint warning, the change looks good and it centers the Got It button correctly vertically / horizontally depending on the screen size.

I'll take a look what's going on, I would expect this kind of things to be automatically fixed 😅

thanks!

prettier is not yet configured, but we should certainly do that.

these linting issues were autofixable so adding lint-staged + husky for running eslint --fix should do the trick
