Multiple borders methods with CSS

I know that many times we are in need to have a box or a side bar where we need multiple borders. And because the box could be rendered dynamically we just can’t afford to have a background and limit the width or height to be fixed.

In this demo I used width and height fixed so they can stay in the same line but that doesn’t mean that it can’t have dynamically width or height.

CSS :before and :after Pseudo-elements

As you already know from the launch of CSS2.1 they implemented the :before and :after pseudo-elements. I know not many people use it but I find it quite helpful.

The :before selector inserts content before the selected element(s).
The :after selector inserts content after the selected element(s).

Browser Compatibility:
IE8 support both pseudo-elements
