Base tag

Base tag

The base tag, represented by <base>, specifies the base URL for all relative links within the HTML code of a specific page or document. 

The base tag must be within the <head> of the code. It doesn’t need a closing tag but does need an href or target attribute. If there’s a target attribute, it will be the default attribute for all hyperlinks within the HTML. 

Here’s a syntax example: <base href="https://www.webflow.com"> 

The base element allows for a default target attribute for all links within the HTML page code. 

Target attribute values include:

  • _self opens the link in the current window
  • _blank — opens the link in a new window
  • _parent opens the link in the parent window if using a frame. Otherwise, it uses the current window.
  • _top opens the link in the topmost browsing content. If there’s no parent browser, it uses the current window.

Here’s another syntax example with target attributes: 

<base href="https://www.webflow.com" target="_blank">

This target attribute would open the link in a new, blank browser window or tab (depending on browser settings).
