Applies a style to the element by adding a CSS declaration.
The first parameter, property, is a string. If the name of a style property is passed, as in myElement.style('color'), the method returns the current value as a string or null if it hasn't been set. If a property:style string is passed, as in myElement.style('color:deeppink'), the method sets the style property to value.
The second parameter, value, is optional. It sets the property's value. value can be a string, as in myElement.style('color', 'deeppink'), or a p5.Color object, as in myElement.style('color', myColor).
