Given a site configuration that contains this menu entry:
{{< code-toggle file="hugo" >}}
[[menu.main]]
name = "IRC"
url = "irc://irc.freenode.net/#golang"
{{< /code-toggle >}}
Attempting to use the `url` value directly in an attribute:
```go-html-template
{{ range site.Menus.main }}
<a href="{{ .URL }}">{{ .Name }}</a>
{{ end }}
```
Will produce:
```html
<a href="#ZgotmplZ">IRC</a>
```
`ZgotmplZ` is a special value, inserted by Go's [template/html] package, that indicates that unsafe content reached a CSS or URL context.
To override the safety check, use the `safeHTMLAttr` function:
```go-html-template
{{ range site.Menus.main }}
<a {{ printf "href=%q" .URL | safeHTMLAttr }}>{{ .Name }}</a>
{{ end }}
```
