Help needed for Image Size IE8

HTML & CSS
1

Hello

I’m trying to set the image size with the following HTML code

img.slide
{
display: block;
margin-left:auto;
margin-right:auto;
height: 60%;
}

It works in Google Chrome but not in IE8, the image size remains the normal size.

Please can someone let me know what I am missing?

Regards.

% heights are often an unattainable goal, unless perhaps there is a fixed height on the container. Do you have an example you could link to?
