Especially when it comes to version differences across Internet Explorer.
Thanks to Trent in the OTN forum, I have this nifty tip if you find some rendering issues in IE10 using APEX that aren't present in 'normal' pages.
Ensure your page template has the meta http-equiv illustrated here
<!--[if (gt IE 9)|!(IE)]> <!--> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> <!--<![endif]-->Instead of
<!--[if (gt IE 9)|!(IE)]><!--> <!--<![endif]-->I found this improved rendering of (amongst now doubt other issues)
- sliders rendered properly;
- login form fields had expected width;
- and the list template "Featured List with Subtext" rendered consistently.
