Removing ::before pseudo element from blog metadata?

In using the Rally template, if you display both primary and secondary blog metadata, it will show as follows:

I'd like to stack the metadata, however, when I adjust the CSS (with my limited knowledge/experience), I'm able to stack it with no issues, but it's carrying the ::before element attached to the secondary metadata (the tags), and no amount of content: none; or display: none; seem to shake it, so it's currently looking like this:

Any suggestions on how I should be laying my CSS out to resolve this? Thanks in advance!

use color: #fff or transparent or font-size: 0 or line-height: 0 or visibility: hidden...for pseudo

Thanks! Could you give me an example of how that line of code would read? I think there may also be an issue with how I'm setting up that sequence.

You don't share link to your site, so i'm not sure exactly code.

it can like this

pseudo-class {
   opacity: 0;
}
