Question

I have a following css

#container
{
        border:1px solid black;
}
#container #header
{
    color:blue;
}

#container #footer
{
    color:red;
}

Can i write it as

#container
{
        border:1px solid black;
        #header
        {
            color:blue;
        }

        #footer
        {
            color:red;
        }
}

So the #header and #footer are still select as #container’s childs element.
Or i need to use some css framework like .LESS ?

Answer 1

Nope, CSS doesn’t support that. I agree, it would be useful. However, you’re right, it looks like LESS supports it.
