Cascading Style Sheets (CSS) specify how certain properties of an element content are rendered. Inheritance rules allow a style attribute to be specified for one parent element instead of specifying it for each element in the hierarchy.
A style attribute can be defined in the following elements: <wml>, <card>, <p>, <anchor>, <img>, <option>, <a>, <input>, <br>, <optgroup>, and <template>.
If not defined specifically, a style attribute value is applied to the element which contains this attribute and all its child elements.
