Can some code block theme options be added in the next release?

Why would I make such a request? Because I looked at many other hugo themes and did not integrate this piece of content, but I found that there is such an option in hexo’s butterfly theme.

For convenience and for beginners, it is recommended that some code style configurations be added to the blowfish theme. I hope this suggestion can be adopted by blowfish authors. thanks @nunocoracao

Currently, I display a mac theme style code block by adding the following code to assets/css/custom.css

.prose .chroma:before {
background: #fc625d;
border-radius: 50%;
box-shadow: 20px 0 #fdbc40, 40px 0 #35cd4b;
content: " ";
height: 12px;
left: 12px;
margin-top: -20px;
position: absolute;
width: 12px;
z-index: 1;
}

.prose .chroma {
padding-top: 30px;
}
