Can the applied styling be based on a property?

[Tiago Machado]

I'll try to explain it better with an example.
Some files have the property "icon" with an emoji. Could this emoji be appended to the links using this plugin?

Could this be done with CSS maybe?

[Emile van Krieken]

Yes, this can be done with css. See the examples in the README.
Something like this should work:

.data-link-icon-before[data-link-icon]::before{
    content: attr(data-link-icon)
}
