Here is some code to shoehorn Paul Irish’s conditional statements for Internet Explorer into Hannon Hill’s Cascade Server using PHP’s ob_start() function. This is a mashup from a few people on the Cascade help forum. Really, it’s a TinyMCE (Cascade’s WYSIWYG editor) hack to get conditional code, i.e. comments, around the HTML tag. I know it’s a very specific use case, but if you are trying to make your web site responsive using HTML5 Boilerplate in Cascade you’ll want this. (Irony: WordPress’s WYSIWYG editor won’t save the code correctly so I took a screen shot.)
UPDATE
Hannon Hill added a set of special tags in version 7.4 of Cascade that allow code – even “illegal” code – to sit in a page unrendered. You’ll find it in their knowledge base under Code Sections. Below is a revised version of the Boilerplate conditional statements using the new “protect-top” tag.
