I do not know how to access a specific CSS using javascript.
Let us say,
#menu { color: red; }
can be accessed by
document.getElementById('menu').style.color = "blue";
But I want to access
#menu li a { height: 10%; }
How do I access that using document.getElementById() ?
Thanks is advance
The .getElementById() function is about getting an element by a unique "id" string. If you need to get elements otherwise, there are other APIs to use: .getElementsByTagName(), .getElementsByClass(), .querySelectorAll(), etc. Browser support varies, and even .getElementById() is different between IE and other browsers.
