Is line highlighting supported?

[johnnymetz]

In other themes, I can highlight a specific line of code (using two backticks below instead of three for display purposes):

```python {hl_lines=[2]}
def hello(name):
    print(f"Hello {name}!")
``

Which renders something like this:

However, using this theme I don't see any highlight on line 2:

Is this a bug or is this not supported?

Remove this rule to restore line highlighting functionality:

hugo-PaperMod/assets/css/common/post-single.css

Lines 196 to 198 in 4e9b047

	.post-content .highlight span {
	background: 0 0 !important;
	}

This works perfectly. Here are images with and without line numbers:

Created a PR to fix this here: #575

Now, in master, I got this problem.😥

[JoJoJotarou]

I found a solution. In mine old config.yml:

markup:
    highlight:
        # anchorLineNos: true
        codeFences: true
        guessSyntax: true
        lineNos: true

this

```html
```

is same as this.

```html {linenos=table}
```

Means the codeblock is rendered as <table> by default.

By https://gohugo.io/functions/highlight/#options

Instead of specifying both lineNos and lineNumbersInTable, you can use the following shorthand notation:

lineNos=inline
equivalent to lineNos=true and lineNumbersInTable=false
lineNos=table
equivalent to lineNos=true and lineNumbersInTable=true

So add lineNumbersInTable=false in config.yml to tell Hugo not use <table> rendering codeblock.

markup:
    highlight:
        lineNumbersInTable: false

now, this

```html
```

is same as this.

```html {linenos=inline}
```

I am sorry that there may be a little bit inconsistent with the theme, I hope to help who have the same problem, so I will not delete the reply, thk.🎇
