Hello OWSC,
We’ve used the shortcodes for blockquote.
You can follow;
1. Go to your Page with the blockquote and then;
2. Go to text tab and use the shortcode as follows;
<blockquote class="orange">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus varius liberus. <cite>Parker Lorem</cite></blockquote>
Note: The color options available are grey, aqua, brown, tan, red, orange, green,etc. You can change the class accordingly.
Let us know!
