Are you a fan of the tag-only posts? In new Tumblr, you’re not allowed to create a post unless you enter something in the title or text field.
But there is a way around it! Hit SHIFT + ENTER once or twice. Or just hit the ENTER key two or three times.
What did you just do, you ask? You added in HTML code for a line break, otherwise known as <br> when you did the SHIFT+ENTER or paragraph breaks with ENTER. Tumblr recognizes this as content, ergo allows you to post a blank post with only tags as actual content again.
You can also do this by hitting the spacebar a few times as well.
Enjoy your tag-only posts!
