# Defining a custom style
```Lua

function undercustom_start(color)
nml.raw.push("inline", "<span style=\"border-bottom: 1px dashed " .. color .. "\">")
end
function undercustom_end()
nml.raw.push("inline", "</span>")
end

nml.custom_style.define_paired("Undercustom Green", "[|", "|]", "undercustom_start(\"Green\")", "undercustom_end()")

Results in the following:
* ``Plain Text,~Dashed underline~`` → ~Dashed underline~
* ``Plain Text,[|Dashed underline|]`` → [|Dashed underline|]
# Limitations
* Custom styles cannot be removed and will be defined through the entire document
* Custom styles defined from lua must have their `start` and `end` functions in the `main` lua kernel.
