    Styling flat radio button and form tabs widgets

    Asked by clewis861 on November 05, 2015 at 12:34 AM
    Is this the case for all widgets?  I can't get the font size to change in any of the widgets I use (Flat Radio Button, Form Tabs, etc)?

    You can add custom CSS inside the widget in order to style it based on your preference.

    In order to change the font size of the label in the flat radio button is you need to apply this custom CSS code. Here's how:

    1. Select the widget and then click the "Wizard" icon.

    2. Go to Custom CSS tab.

    3. Put this CSS code on the box.

    label {

    font-size: 20px !important;


    4. Click the finish button when you're done.


    You can also add custom CSS in the Form tabs widget. Just select the widget and then click the "Wizard" icon. If you scroll down, you'll see the box where you can add CSS.

    Hope this helps. Let us know if you need further assistance. Thank you.
