https://i.stack.imgur.com/scn6l.png

I need to create a list with katakana, so I created a class .lisDestaq with list-style-type:katakana, but when I load the class in div it doesn't work.

.lisDestaq{
color:#2255AA;
list-style-type:katakana;
}

then on html

<div class="lisDestaq">
    <ul>
        <li> Death Note </li>
    </ul>

but the katakana doesn't show up I can just put in css ul{list-style-type:katakana;} and it works, but I want to set it into the class, can somebody help me? why isn't working?
