如何增加字母间距以下拉选项？

Question

I would like to add letter spacing to the drop down options. Only the highlighted text seems to be working fine not the options.

Here is my code:

.uDDL select
{
    -webkit-appearance: none;
    -moz-appearance: none;
    font-family: 'HelveticaNeue LT 47 LightCn', 'HelveticaLightCondensed', Sans-         Serif;
    top: 11px;
    right: 15%;
    border: 0px;
    outline: 0px;
    font-size: 22px;
    letter-spacing: 1px;
    position: absolute;
    cursor: pointer;
    display: inline-block;
    height: 29px;
    width: 296px;
    background: transparent;
    padding-left: 39px;
}
.DDL select::-ms-expand {
    display: none;
}
.uDDL option 
{
    font-family: HelveticaLightCondensed;
    font-weight: bold;
    letter-spacing: 1px;
    background: white;
    text-align: center;
}

You are most likely not calling the elements correctly so try to check your css combination again. Also if you want more help, post your CSS and HTML code along with anything that you have tried.
