-The [`anchorize`] and [`urlize`] functions are similar: 
-
-[`anchorize`]: /functions/urls/anchorize
-[`urlize`]: /functions/urls/urlize
-
-- Use the `anchorize` function to generate an HTML `id` attribute value
-- Use the `urlize` function to sanitize a string for usage in a URL
-
-For example:
-
-```go-html-template
-{{ $s := "A B C" }}
-{{ $s | anchorize }} → a-b-c
-{{ $s | urlize }} → a-b-c
-
-{{ $s := "a b   c" }}
-{{ $s | anchorize }} → a-b---c
-{{ $s | urlize }} → a-b-c
-
-{{ $s := "< a, b, & c >" }}
-{{ $s | anchorize }} → -a-b--c-
-{{ $s | urlize }} → a-b-c
-
-{{ $s := "main.go" }}
-{{ $s | anchorize }} → maingo
-{{ $s | urlize }} → main.go
-
-{{ $s := "Hugö" }}
-{{ $s | anchorize }} → hugö
-{{ $s | urlize }} → hug%C3%B6
