I would love the ability to create this little sidebar element on ALL sides of a blockquote element. Is there a Tips&Tricks somewhere here that explains how this would be done?
I think the padding and overflow traits help to create this partial border; what inline styling can be applied to shift the border to the other sides?
That effect is achieved by adjusting the border and background colors of a blockquote. The same effect can be achieved with any element. A basic blockquote has a left padding of 15px (which accounts for the spacing you are seeing) and a solid left border of 5px.
Let's say that we want to make a paragraph that looks something like the screenshots you supplied.
Give it 15px of padding on all sides using the Margins & Padding for Current tool in the Customize the Style section of the tools
Giving you something like this:
Set a 5px solid border for all sides in your color of choice using the Borders for Current Element tool.
Give it a background color using the Colors for Current Element tool
Giving you a finished product that looks something like this:
Hopefully that helps and have a wonderful day.
