We are using Interface Pro on http://www.family-historian.co.uk/store
There is a table controlled with a little extra css as follows.
table.buynow tr td:first-child { width: 20%; }
.alt { background: #F5FBF9;}
.alt {background: #F1F3EB; }
The table renders fine in Chrome and Firefox, but on IE 11 it drops the text in the second and third cells down, I have been unable to spot the problem and wondered if you could help to identify the issue.
