## Line Numbers, Highlight Lines

### Line Number (table) and Highlight Lines

`linenos=table` will give copy-and-paste friendly code blocks.

    ```c {linenos=table, hl_lines=[1,"3-4",8], linenostart=199}
    // codes ...
    ```

```c {linenos=table, hl_lines=[1,"3-4",8], linenostart=199}
int main() {
    int a = 1;
    if (a == 999)
        // This is a very long comment to test the `overflow` attribute defined in CSS. The `overflow` property in CSS deals with the content when it overflows the block-level container. It can take the following values: `visible` (default), `hidden`, `scroll`, `auto`, and `clip`.
        // If `visible` is specified, the content is not clipped and can render outside the container. If `hidden` is specified, the content is clipped and the rest of the content will be invisible. If `scroll` is specified, the browser should provide a scrolling mechanism for the user to access the clipped content.
    }
    return 0;
}
```

### Line Number (true) and Highlight Lines

    ```c {linenos=true, hl_lines=[1,"3-4",8], linenostart=1}
    // codes ...
    ```

```c {linenos=true, hl_lines=[1,"3-4",8], linenostart=1}
int main() {
    int a = 1;
    if (a == 999)
                // This is a very long comment to test the `overflow` attribute defined in CSS. The `overflow` property in CSS deals with the content when it overflows the block-level container. It can take the following values: `visible` (default), `hidden`, `scroll`, `auto`, and `clip`.
        // If `visible` is specified, the content is not clipped and can render outside the container. If `hidden` is specified, the content is clipped and the rest of the content will be invisible. If `scroll` is specified, the browser should provide a scrolling mechanism for the user to access the clipped content.
    }
    return 0;
}
```

### Line Number (inline) and Highlight Lines

    ```c {linenos=inline, hl_lines=[1,"3-4",8], linenostart=1}
    // codes ...
    ```

```c {linenos=inline, hl_lines=[1,"3-4",8], linenostart=1}
int main() {
    int a = 1;
    if (a == 999)
                // This is a very long comment to test the `overflow` attribute defined in CSS. The `overflow` property in CSS deals with the content when it overflows the block-level container. It can take the following values: `visible` (default), `hidden`, `scroll`, `auto`, and `clip`.
        // If `visible` is specified, the content is not clipped and can render outside the container. If `hidden` is specified, the content is clipped and the rest of the content will be invisible. If `scroll` is specified, the browser should provide a scrolling mechanism for the user to access the clipped content.
    }
    return 0;
}
```

### Line Number (false) and Highlight Lines

`linenos=false` will turn off line numbers if it’s configured to be on in site configuration.

    ```c {linenos=false, hl_lines=[1,"3-4",8]}
    // codes ...
    ```

```c {linenos=false, hl_lines=[1,"3-4",8]}
int main() {
    int a = 1;
    if (a == 999)
                // This is a very long comment to test the `overflow` attribute defined in CSS. The `overflow` property in CSS deals with the content when it overflows the block-level container. It can take the following values: `visible` (default), `hidden`, `scroll`, `auto`, and `clip`.
        // If `visible` is specified, the content is not clipped and can render outside the container. If `hidden` is specified, the content is clipped and the rest of the content will be invisible. If `scroll` is specified, the browser should provide a scrolling mechanism for the user to access the clipped content.
    }
    return 0;
}
```
