I am creating a website and I need some box style like this. Although, their speed has not been fixed for its dynamic content, I used to use the -webkit-border-image and -moz-image-border and completely Unfortunately, IE is bad bad guy and I want to display it properly.

I thought that with box-shadow and -webkit-gradient and -moz-linear-gradient with CSS3 But IE does not work again

I should know some CSS techniques so that I have a gradient box and shadow << Class> "post-text" itemprop = "text">
