Use the End-User Cascading Style Sheet in Answer Previews
You can use the cascading style sheet (CSS) from your customer portal when previewing answers, to get a better idea of how they will look to the end user. To do this, you must modify the standard answer workspace.
Note: The Service Console uses custom
                code and settings to render previews. Therefore, the appearance of an answer in a
                preview will not look exactly as it will on your customer portal.
- Copy the standard answer workspace, then open the copy for editing.
 - Click the Design tab.
 - On the Content tab in the workspace, click the Answer Type Container control.
 - On the Design tab, select the Apply End User CSS check box.
 - Save the modified workspace.
 
What to do next
Edit the profiles of staff members to use the modified workspace. See Add or Edit a Profile.
