Scripting Inline Styles

The most straightforward way to script CSS is to alter the style attribute of individual document elements. Like most HTML attributes, style is also a property of the Element object, and you can manipulate it in JavaScript. The style property is unusual, however: its value is not a string, but a CSSStyleDeclaration object. The JavaScript properties of this style object represent the CSS properties specified by the HTML style attribute. To make the text of an element e big, bold, and blue, for example, you can use the following code to set the JavaScript properties that correspond to the font-size font-weight and color style properties: = "24pt"; = "bold"; = "blue";
