If you want to do that on one page, then you just need to use Wikitext and/or a bit of HTML to get that effect.

If you want to be able to put it on many pages, that's done with a template. The brief answer is that you:


 * Create a page called Template:Name (with "name" being whatever you want to write to use the template).
 * Add the text and/or images you want to use on multiple pages.
 * Use Wikitext or a bit of HTML to give it the look you want.
 * Add it to articles by typing

There's much more you can do with templates beyond this. Have a look at Help:Templates for more.
