Here is a very simple trick that can help you highlight a sentence or two in your Craigslist ad by making the text bold or putting it in italics. All you will need to do is add some very simple HTML coding before and after the text you want highlighted. These HTML codes need to be inserted when you create your description on your Craigslist ad.
Bold and Italics HTML Examples
Please see the examples below. The first screen cap shows the codes you will need to put around the text in your item description. The second screen cap shows the results when the ad is live on Craigslist.
