How to customize the WooCommerce checkout page & fields with CSS

There are two types of fields in WooCommerce: product and checkout fields. And you can personalize both of them! In this article, you'll learn how to assign a custom field class and use CSS to style the WooCommerce checkout page. I will be customizing WooCommerce checkout page fields with CSS with the free design plugin as well.

In general, there is no easy way to personalize checkout or product fields in WooCommerce. So you need to use default fields & their classes. But if you want to assign a CSS custom field class to any checkout or product field, you need a plugin.

➡️In this guide, you'll learn how to change the look of the WooCommerce checkout page & product fields. Look at the default Upload field:

Free plugins to personalize fields in WooCommerce

So, let's start with these two FREE plugins that will help you adjust the fields and the design of checkout and product pages in WooCommerce!

Flexible Checkout Fields

Flexible Product Fields

Customizing the WooCommerce checkout page with CSS

Let's begin with Flexible Checkout Fields.

1. Assign a CSS custom field class to any field

   Once you install and activate the plugin, go to WooCommerce → Checkout Fields.

2. Open the Checkout Section to edit the fields

   

   Now, select a field by simply clicking its name. You will see 6 tabs.

3. Choose the Appearance tab

   You may set your CSS class here:

   

4. Add custom CSS for the WooCommerce checkout page

   So, you have now this new CSS class that you can use for the field to personalize the WooCommerce checkout page design. Scroll down to an example ↓

Use custom CSS for the new product fields

👉🏼 Next, let's see how it works for Flexible Product Fields. By default, there are no product fields in WooCommerce. So, first you need to create additional product fields so that you can style them.

1. Install and activate the plugin

   First, get the free plugin to start customizing the product fields in WooCommerce.

2. Configure the fields

   Then, go to Products → Product Fields:

   

3. Add new fields

   Now, let's create a group of fields with a field inside.

   

   This is how it looks like on the product page:

   

4. 💡 If you need more help with that, check out our WooCommerce Extra Product Options Guide →

5. Set the CSS class for the field

   Here, you will find a CSS Class option inside a field's configuration screen.

   

6. Personalize the product page with the theme customizer

   Finally, open the Appearance tab → Customize to add custom CSS rules (like in the example below).

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

Add CSS rules in your theme (for the WooCommerce checkout page)

To add custom CSS go to the Appearance menu → Customize.

Use the Additional CSS section to add custom styling to your WordPress theme.

Example

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

➡️ We need a CSS class. I've added one called 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:
