You'll need to inspect the HTML and find this snippet, then you can use CSS to customize the elements in there:

[data-field="testdate"] {
    color: rgb(74, 74, 74) !important;
    font-size: 20px;
    background-color: rgb(243, 243, 243);
}

If you let me know what exactly you'd like to be changed, I can provide a little more specific CSS.
