Board Thread:Support Requests - Designing Your Wikia/@comment-25397951-20141124044801/@comment-23989026-20141124155919

To use an existing template, you need to copy the coding. Visit the template page, click EDIT and copy. Create a page of the same name on your wikiA (eg:Template:CharPortalAAA) and paste the code. Before PUBLISH, click PREVIEW. If you see "red ink" it means that the template includes additional styling template(s). So you would need to create these templates on your wikiA following the above method.

To give you an example, I have added Template:CharPortalAAA on the-fearless-signature. To test it is working correctly, I have used it on the main page. The blue header is #7878FF. So that is the default border/background color. But I have added a background-color option letting you change the color (see w:c:the-fearless-signature:Template:CharPortalAAA)
