Set Your Own CSS Class to Any Custom Fields in Your WooCommerce Store

There are two types of custom fields: product and checkout fields. You can personalize both of them. All you need is to assign your own custom field class from your CSS file. In this guide, I'll show you how to make it.

In general, there is no easy way to personalize checkout or product fields. If you want to assign a CSS custom field class to any field, you need a plugin.

In this guide, you'll learn how to change the look of the fields. Look at the default Upload field:

You can change its look to this:

That's just an example. You will set your own styling.

There are two great plugins for custom fields:

• Flexible Checkout Fields
• Flexible Product Fields

These plugins let you configure fields and create custom fields, too. You can check out our tutorial: Create Custom Fields in WooCommerce →

Download one or both of them using links above to continue with this guide.

Assign a CSS custom field class to any field

Let's begin with the Flexible Checkout Fields plugin. Once you install and activate it, go to WooCommerce → Checkout Fields. You will find Edit Section in there:

Now, select a field by simply clicking its name. You will see 4 tabs. Choose the Appearance. You may set your own CSS class there:

Next, let's see how it works for Flexible Product Fields. There are no product fields by default in WooCommerce. You need to create some and then you can style them.

Go to Products → Product Fields:

Then create a group of fields and a field inside. If you need more help, check out our WooCommerce Extra Product Options Guide →

You will find a CSS Class option inside a field's configuration screen.

You've just learned how to set your own styling for both checkout and product fields.

Example

Let's say we want to style radio button field.

We need to create a CSS class. I created the example-class. As you may see below, I also wrote some code for fieldset, legend and label elements:

This code lets me transform this field:

Into such a beauty like this:

OK. Maybe it's not the most beautiful radio button out there but I like it :)

Anyway, you get the idea. The plugin assigns your CSS custom field class to the field's div:

If you want to customize elements inside this div, you need to call them like this:

for a legend element:

That's because this element is nestled inside the div and a fieldset element:
