The DOM has three CSS-related methods that apply to the style object that maybe you've never seen before. They are: setProperty(), removeProperty(), and getPropertyValue(). As is always true of the style object, the use of these methods is pretty limited because these only deal with inline styles, not styles set in a style element or in an external stylesheet.
The methods are pretty self-explanatory, and you'll notice they bear some resemblance to jQuery's CSS-specific features. Let's see examples of each one in use.
To set or remove the value on a property as an inline style, we use setProperty() and removeProperty():
As you can see, to define the property, we just include it as the first argument to the setProperrty() method, which needs to be called on the style object, not on an element directly. The value is the second argument. Removing a property requires only a single argument, the property we want to remove.
Note that the way we reference the properties here is different from how we reference them when using them directly on the style object. On the style object, we have to remove the hyphen and camel-case the property name, whereas here we use the standard CSS name for it.
Finally, there's the getPropertyValue() method, which might be a little more useful than the others. This one allows you to get the current value of a specific property that's set as an inline style:
Because this method reads the property's value, we're logging the result. Similar to the other methods, we just pass the CSS property name as the lone argument.
Here's a full JS Bin example that lets you apply these methods by clicking the buttons on the page, allowing you to see the results applied to the elements visibly. These methods are supported in all browsers, including IE9+. Here's more info on Microsoft's IE Dev Center pages:
