If it's an article from a website, first, take a screenshot of the relevant part of the article. Then, depending on the social media platform where you want to share it as a story, like Snapchat or Instagram, you can go to the story creation section and add the screenshot. But always be aware of copyright laws and get permission if necessary.
Another option could be to create a short summary of the article in your own words and then add that as text in your story. You can also mention the source of the article. This way, you are sharing the essence of the article without directly using its visual content. However, make sure you still adhere to any rules or regulations regarding sharing information from other sources.
Some news apps or content platforms may have a built - in sharing feature. For example, if the article is from a news app that is integrated with social media, there might be a share button that gives you options to share directly to your story on certain platforms. But this is not very common. In most cases, you'll need to use the screenshot method and be cautious about respecting the original author's rights.
