Change the Font for Dropdown Lists of Online Customer Forms

In order to change the font size of text inside dropdown lists, users can specify CSS within the Online Customer Form and have the following set in it:

.inputreq{
font-size: 20pt !important;
}

This ensures that any other CSS specified for this class are overriden (those that are specified in Setup > Site Builder > Themes). This sample will generate fonts of size 20pt for the text inside dropdown lists.
