Justify right

Yep, just use the float property, https://developer.mozilla.org/en-US/docs/Web/CSS/float, you might have to attach !important to override the default css.

Thanks.

However…
adding css for float ( float: right; ) in the simple-banner-text on config page results in the text adjusting right, but clears out the SB background color. Same with float: left;

Ah gotcha. May want try try text-align instead https://developer.mozilla.org/en-US/docs/Web/CSS/text-align
