Use the shortcode [blur][/blur] to blur text.
For example: 
[blur]This text will be blurred[/blur]
Optionally, you can set the blur to be removed when the user clicks or hovers on it.
Here are the shortcode examples for that:
[blur toggle=click]This text will be blurred until it’s clicked on[/blur]
[blur toggle=hover]This text will be blurred until it’s hovered over[/blur]
Be default, the blurred text color will be black. You can specify a different color like this:
[blur color=orange]This text will be orange, even when blurred.[/blur]
[blur color=#00FF00]This text will be green, even when blurred.[/blur]

Blur Text

Blur Text with a shortcode.  Unblur with a click or hover.  Specify a blur color.
