The Style object is part of the Webflow Designer API. It represents a style that can be applied to Webflow elements on the canvas.

It provides numerous methods for managing CSS properties across different breakpoints and pseudo-states. From creating new styles to setting and retrieving properties, the Style Object is your primary tool for managing the look and feel of your Webflow designs."

📘

Using CSS Properties

Please use use the long-form alias of a css property when managing styles. For example, the property row-gap has a long-form alias of grid-row-gap which you can find the the MDN CSS Properties reference.

Creating Style Objects

To create a Style, use the createStyle method of the webflow object. This method takes the name of the new style as an argument and returns a new Style object.

let myStyle = webflow.createStyle('myNewStyle');
// myStyle is now a Style object with the class name 'myNewStyle'

Once a Style is created, it can be used to manage CSS properties for elements on the Webflow canvas. Note that the createStyle method will always create a new style, even if a style with the same name already exists. If you want to modify an existing style, you should retrieve it using the appropriate method from the API rather than creating a new one.

myStyle.destroy();

Breakpoints and Pseudo-States

The BreakpointAndPseudo type is used to specify breakpoints and pseudo-states for the getProperties, setProperties, getProperty, and setProperty methods. It is an object that can have breakpoint and pseudo properties.

Valid values for breakpoint are:

• 'xxl',
• 'xl',
• 'large',
• 'main',
• 'medium',
• 'small',
• and 'tiny'.

Valid values for pseudo are

• 'noPseudo',
• 'nth-child(odd)',
• 'nth-child(even)',
• 'first-child',
• 'last-child',
• 'hover',
• 'active',
• 'pressed',
• 'visited',
• 'focus',
• 'focus-visible',
• 'focus-within',
• 'placeholder',
• 'empty',
• 'before',
• and 'after'.

These options allow you to specify styles that will apply under different conditions, such as different viewport sizes (breakpoints) or different states of an element (pseudo-states).

For example, you could use the setProperty method to set the color of a text element to red when it is hovered over on medium-sized screens:

myStyle.setProperty('color', 'red', { breakpoint: 'medium', pseudo: 'hover' });

Likewise, you could use the getProperties method to get all the properties that apply to an element when it is the first child of its parent on small screens:

let properties = myStyle.getProperties({ breakpoint: 'small', pseudo: 'first-child' });
// Do something with properties

This flexibility allows you to create responsive designs that adapt to different screen sizes and interactive designs that respond to user actions.
