I see a lot of people complaining that they cannot preview their articles, so they have to edit it after it's released.
There is a way to preview it, it's not the best, but it works until Steemit's preview button appears. I think they will do it soon because of the features they are working on.
If you start a new article, click the Edit button.
Start writing your article now, and if you want to preview your article, click on the original HTML button.
First you will see the original HTML text, below you will see a preview of your article. Examples include your picture or clip.
When you're writing a longer article, you have to scroll down to see the preview.
To go back to your article, click the edit button again.
It's a bit roundabout, but it's no more frustrating than editing your post after posting.
