To format your product description and add additional languages, go to Products and Settings > Products and Pages > (Product) > Description and Image > Edit. Locate the field called Description.
Basic HTML tags are supported for formatting the presentation of your text. Some common examples you may want to use:
<p>Paragraph</p><b>Bold</b><i>Italic</i><span style="color:red;">Red Text</span><br/><br/><br/>Line Breaks<a href="http://www.google.com" target="_blank">Link which opens in a new window</a>
Sometimes you will run into a problem where the HTML tags show up literally on the page itself. The problem here is almost always that the HTML is not properly formed. All tags need to be closed <tag>xxx</tag> or <tag/>.
In HTML, there are certain characters or letters that need to be replaced with a special code or the formatting of the page won't work properly. Some common common problems with the codes to replace them:
