How to apply !important using .css()?

Question

I am having trouble applying a style that is !important. I’ve tried:

$(\"#elem\").css(\"width\", \"100px

An alternative approach is dynamically creating and updating CSS class in JavaScript. To do that, we can use style element and need to employ the ID for the style element so that we can update the CSS class

function writeStyles(styleName, cssText) {
    var styleElement = document.getElementById(styleName);
    if (styleElement) document.getElementsByTagName('head')[0].removeChild(
        styleElement);
    styleElement = document.createElement('style');
    styleElement.type = 'text/css';
    styleElement.id = styleName;
    styleElement.innerHTML = cssText;
    document.getElementsByTagName('head')[0].appendChild(styleElement);
}

...

  var cssText = '.testDIV{ height:' + height + 'px !important; }';
  writeStyles('styles_js', cssText)
