[michalstruck]

@michalstruck I am getting the following error when I try to run yarn dev. This happens on portfolio page. This error doesn't happen on upstream/master branch.

ReferenceError: Box is not defined
  11 |     <div className="portfolio-page">
  12 |       <Header bgImg={homePageBg} title={title}>
> 13 |         <Box className="careers-container">
     |         ^

There is an error that needs to be fixed.
