I see you pasted the css in your stylesheet.

You’ve put it inside a media query. Put it outside the media query and the changes should take effect.

Change this:

.rpbt_container{
	float: right;
	padding: 1em 1em;
	background-color: #E3E3E3;
}

}

to this:

}

.rpbt_container{
	float: right;
	padding: 1em 1em;
	background-color: #E3E3E3;
}

Ha! Beauty. Nice work!!!

Maybe add a width: 50%; in .rpbt_container css rule.

Try resizing your browser window and see what happens. There’s lots more to do for visitors with a smaller screen size (media queries).

The css is very basic for what I think you want. Read the css tutorial I linked above to learn how you could style the related posts further. Create a new topic in the forums if you have trouble with the css.

Thanks again. I’ll play with the css a little. I really appreciate your effort. Fast and courteous support!
