Hi @Jennifer,
You can use following CSS code in <b>Appearance-> Customize-> Theme Options -> Custom CSS</b> box:
ul li {
list-style-type: "✝";
}
Note: Specifying Wingdings 2 font is contrary to the published specifications, has never been a documented feature of HTML, is not reliable, and should not be done. Wingdings 2 is not available on all computers, and so the intended characters may not appear on computers running non-Microsoft operating systems such as Mac OS 9, Mac OS X 10 or Linux. The intended characters are also unlikely to appear when using a standards-compliant browser such as Firefox, Google Chrome, Netscape 6+, Opera 6+, Safari 3+ or SeaMonkey (formerly Mozilla). The same problems are found with the Webdings, Wingdings and Wingdings 3 fonts – they should not be used in Web pages.
Regards,
Pratik
