# JavaScript - get CSS style

Sometimes i want to use JavaScript get dom CSS style.

Use DOM.currentStyle and window.getComputedStyle(DOM)

For IE use DOM.currentStyle

Other use window.getComputedStyle(DOM)

var dom = document.getElementById("target"),
    style = dom.currentStyle || window.getComputedStyle(dom);
console.log(style.marginTop);

refer - Window.getComputedStyle() - Web APIs | MDN

refer - currentStyle object (Internet Explorer)
