Custom CSS classes
Amplify General class names for Widgets
Root component class for all widgets
.picky-widget
Add global picky-widget class before each CSS rule, for example:
/* Set red color for cart title */
.picky-widget .picky-cart__title { color: red; }
/* Set 1.5rem font-size for cart line-item */
.picky-widget .picky-cart-item__title { font-size: 1.5rem; }
You can modify colors, fonts, sizes, margins, padding, and other styling elements.
Can I revert to the default styling?
Yes, removing your custom CSS will revert the styling back to its default.
How do I preview the changes made by custom CSS?
When you open the Custom CSS tab, a preview screen appears on the right side. After inserting CSS styles, you can see their effects in the preview.
To perform a more thorough check, we recommend publishing the changes and reviewing the display on the live storefront.
What happens if I add incorrect CSS?
Incorrect CSS might break some styles or have no effect at all; however, removing or correcting the code should restore the original appearance.
Is there a limit to how much CSS I can add?
There’s generally no strict limit, but overly complex or large CSS files may slow down your store’s performance.
