Badge style "for-the-badge" allowed?

[elliotwutingfeng]

I want to place a "mentioned in awesome" badge on my awesome project's readme, in the style of "for-the-badge", but there is currently no such option available (the existing flat version is smaller than "for-the-badge" badges and would look out of place in this repo https://github.com/elliotwutingfeng/go-fasttld).

Is it against the rules to use my own "for-the-badge" badge like this?

Feel free to use that. And also feel free to add it to https://github.com/sindresorhus/awesome/blob/main/awesome.md#awesome-mentioned-badge
