Javascript Style Presentation

What does style in Javascript allows us to do?

    It allows Javascript to directly manipulate CSS properties right in JavaScript using the style property. Resulting in a style change in HTML.
    As content gets more complex you want it to run first. That's why you want to use JavaScript style.
    Styles you can change in Javascript-Margins(bottom,left,right,top),background color, Font(family,style,variant,weight), line height, text align(justify,center,left,right), text decoration(underline,overline),text tranform(capital,upper,lower), and verticle alignment(baseline)
