title: relURL
description: Returns a relative URL.
categories: [functions]
menu:

parent: functions
keywords: [urls]
signature: ["relURL INPUT"]
---
With multilingual configurations, use the [`relLangURL`] function instead. The URL returned by this function depends on:
- Whether the input begins with a slash
- The `baseURL` in site configuration
### Input does not begin with a slash
If the input does not begin with a slash, the resulting URL will be correct regardless of the `baseURL`.
With `baseURL = https://example.org/`
```go-html-template
{{ relURL "" }} → /
{{ relURL "articles" }} → /articles
{{ relURL "style.css" }} → /style.css
```
With `baseURL = https://example.org/docs/`
```go-html-template
{{ relURL "" }} → /docs/
{{ relURL "articles" }} → /docs/articles
{{ relURL "style.css" }} → /docs/style.css
```
### Input begins with a slash
If the input begins with a slash, the resulting URL will be incorrect when the `baseURL` includes a subdirectory. With a leading slash, the function returns a URL relative to the protocol+host section of the `baseURL`.
With `baseURL = https://example.org/`
```go-html-template
{{ relURL "/" }} → /
{{ relURL "/articles" }} → /articles
{{ relURL "style.css" }} → /style.css
```
With `baseURL = https://example.org/docs/`
```go-html-template
{{ relURL "/" }} → /
{{ relURL "/articles" }} → /articles
{{ relURL "/style.css" }} → /style.css
```
{{% note %}}
The last three examples are not desirable in most situations. As a best practice, never include a leading slash when using this function.
