Fylo data storage component using SASS, Grid and Flexbox

Designing the "185 GB LEFT" message pop-up was pretty challenging, but fun! I had to make two separate pseudo elements (::before and ::after) for the message, one for the bolded "185" text and other for the non bolded "GB LEFT". Apparently you cannot have different font weights on a single content in a pseudo element, you would need both before and after. Is there any (better) way to create this message in the code?
