At yesterday's I / O 2019 developer conference, Google unveiled a new technology called Portals, which aims to offer a new way to load and navigate web pages.
According to Google, the Portals feature will work with the help of a new HTML tag called <portal>. This tag will work similarly to the classic tags <iframe >, and allow web developers to embed remote content into their pages.
The difference between a Portal and an iframe tag is that Google's new Portals technology is an upgrade of iframes. Google says Portal tags will allow users to browse through the content they embed - something that iframes do not allow for reasons security.
In addition, Portals will be able to change the base URL, which means that they will be more useful as a navigation system than content integration, which is the most common way iframes are used today.
Google engineers hope that the new Portals technology will be used extensively on the web and will become the standard way for websites to exchange links.
For example, the company's engineers hope that when a user browses a news site, when they reach the end of a story, the relevant links to other stories can be incorporated as Portals. So with one click the user will be able to change seamlessly to a new page.
The advantage of Portals over classic links is that content through Portals can be uploaded in advance without waiting for the user to upload.
The feature was first announced at the Chrome Dev Summit last November, but starts today. Portals are supported in the latest version of Chrome Canary for Android, Mac, Windows, Linux and Chrome OS.
To enable it, you need to open the Chrome internal address: chrome: // flags / # enable-portals.
Currently the feature is only available in Chrome Canary, and if you want to see with a demo, you can do so from here.
