Obtaining the Applied Font When Undefined in CSS
In web development, it may be necessary to access the actual font used to render an element when CSS does not explicitly specify it. This can occur in cases where the text is inherited from default styles or hidden within the system or browser's default settings.
To retrieve this information, you can utilize the getComputedStyle function:
function css(element, property) { return window.getComputedStyle(element, null).getPropertyValue(property); }
This function takes two parameters: an element and a CSS property. For example, to determine the font size of an object, you would use:
css(object, 'font-size') // returns '16px' for instance
It's important to note that this method is not supported by IE8.
