Currently we are converting the md files in to html files using Jekyll.

I would like to highlight the some of the code snippet lines like below.

Could you please help me achieve this ?

Am using **jekyll 4.2.1**

Thanks in advance.

not sure it can be done - jekyll uses rouge for highlighting and it didn’t used to support this, I see now that if does:

> <https://github.com/rouge-ruby/rouge/pull/1426>
>
> \- add line highlighting option to HTMLLinewise formatter
> \- add dedicated format…ter to add line highlighting (only marks highlighted lines)

but I don’t think jekyll supports the new option in rouge.

In rouge it is here:  
[GitHub - rouge-ruby/rouge: A pure Ruby code highlighter that is compatible with Pygments](https://github.com/rouge-ruby/rouge#formatters) – `Rouge::Formatters::HTMLLineHighlighter.new(formatter, highlight_lines: [3, 5])`
