Hi Thomas,

Use below CSS code to change the font size as well as to disable call to action button:

For primary text:

.widget_promotional_bar .promotional-text {
    font-size: 32px;
    line-height: 39px;
}

For secondary text:

.widget_promotional_bar .promotional-text span {
    font-size: 16px;
    line-height: 23px;
}

For to disable button:

.widget_promotional_bar .call-to-action {
    display: none;
}

Increase/Decrease above digit value to change the font size as well as line height.

Thank you!
